[D] Regarding the issues related to the homepage in Superset version 5.0.0 [superset]
GitHub user igarashi-futaba created a discussion: Regarding the issues related to the homepage in Superset version 5.0.0
I have deployed Superset 5.0.0 locally. I want users to see dashboard previews instead of a dashboard list on the homepage after logging in. Can version 5.0 achieve this? How should I configure it?

Superset 5.0.0 does not support default hiding of charts in dashboards through configuration or chart settings. The hide/show toggle in the dashboard UI is a manual, user-driven action and isn't backed by any persistent setting or metadata. All charts are displayed by default when a dashboard loads, and there is no built-in way to have certain charts hidden initially—even if you set them as hidden in chart settings, this state isn't saved or applied on dashboard load. Implementing default hidden charts would require custom development in the dashboard layout or metadata logic, as it's not a feature in the current release.

You can adjust font size individually for some chart types in Superset 5.0. For example, BigNumber charts have controls for header, subtitle, subheader, and metric name font sizes—look for these options in the chart's control panel, where you can select from values like Tiny, Small, Normal, Large, and Huge. Word Cloud charts also let you set minimum and maximum font sizes directly in their control panel settings.
However, for ECharts (like bar or line charts), Superset does not currently support customizing axis label font size or color through the UI or chart configuration. These properties are set in the frontend code and are not exposed for user override; changing them would require modifying the source code or requesting a feature enhancement from your Superset admin or developers. There is no built-in workaround for axis label font size in ECharts charts at this time [reference](https://github.com/apache/superset/discussions/35775).
BigNumber chart font size controls example:
- `header_font_size`, `subtitle_font_size`, `subheader_font_size`, `metric_name_font_size` (selectable in the chart editor)
Word Cloud chart font size controls example:
- "Minimum Font Size" and "Maximum Font Size" (integer values in the control panel)
[reference](https://github.com/apache/superset/blob/master/superset-frontend/plugins/plugin-chart-word-cloud/src/plugin/controlPanel.ts)
[reference](https://github.com/apache/superset/blob/master/superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/sharedControls.ts)
If you need font size customization for a specific chart type, let me know which one and I can check for available options or workarounds.

[@dosu](https://go.dosu.dev/dosubot)I've successfully enabled the thumbnail feature toggle, but all dashboard preview images are blank. Where should I adjust the configuration? Additionally, can a default homepage dashboard be configured per user? This would redirect users directly to a specified dashboard upon login instead of the welcome homepage.

For blank dashboard thumbnails, make sure you have these feature flags enabled in your superset_config.py:
```python
FEATURE_FLAGS = {
"THUMBNAILS": True,
"THUMBNAILS_SQLA_LISTENERS": True,
"PLAYWRIGHT_REPORTS_AND_THUMBNAILS": True,
}
```
You also need to have Celery workers running and a cache backend (like Redis) configured and available. If these are missing or not running, thumbnails will stay blank. If your dashboards only have markdown (no charts), thumbnail generation can fail due to Playwright timeouts—this is a known issue. You can try adjusting screenshot-related config flags (like SCREENSHOT_TILED_ENABLED and thresholds), but they only take effect if PLAYWRIGHT_REPORTS_AND_THUMBNAILS is enabled. Check your worker logs for errors if thumbnails still don’t appear.
[Reference](https://github.com/apache/superset/issues/33132) | [Config details](https://github.com/apache/superset/blob/master/superset/config.py) | [Celery/cache requirement](https://github.com/apache/superset/blob/master/superset/models/dashboard.py)
Superset does not support per-user homepage dashboard redirects out of the box. There is a DASHBOARD_TEMPLATE_ID config that copies a template dashboard to new users and sets it as their welcome dashboard, but this only applies to new users and not as a redirect for existing users.

This error happens because your browser is too old and doesn't support the JavaScript `Set.prototype.difference` method, which Superset dashboards use starting in version 5.0.0. Charts work because they don't use this method. To fix it, upgrade your browser to Chrome 122 or newer (or another browser that supports this feature). Check if the affected network segments are using outdated browsers or have policies that force old versions—updating them will resolve the issue.

In Superset 5.0.0, I noticed that in dashboards or charts, you can hide or show a chart by clicking on the icon in the top right corner.

<!-- Answer -->
Permalinks generated via the dashboard share feature in Superset 5.0.0 are stable and deterministic—they remain valid and unchanged as long as the referenced dashboard exists and the permalink entry hasn't expired or been deleted. If the dashboard is deleted or its UUID changes, the permalink becomes invalid. By default, permalinks do not expire unless an expiration is set, but they represent a snapshot of the dashboard's state at the time of creation, not a dynamic view that updates with dashboard changes [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/commands/dashboard/permalink/create.py#L39-L85)].
Superset does not support assigning different permalinks as default homepages for different users out of the box. The only built-in per-user homepage redirect is via the `welcome_dashboard_id` attribute, which is set for new users if you use the `DASHBOARD_TEMPLATE_ID` config. For more advanced per-user homepage logic (like redirecting users to different permalinks), you would need to implement a custom IndexView using `FLASK_APP_MUTATOR` in your `superset_config.py` [[discussion](https://github.com/apache/superset/issues/34575)].
For horizontal bar charts with multiple Y-axis dimensions, Superset only supports sorting by aggregated metric values (like sum, min, max, avg) or by specifying `order_by_cols` in the chart controls. There is no built-in way to sort the Y-axis by the raw values of a single dimension in multi-dimensional charts. The "sort query by" control only affects metric-based sorting, not dimension sorting—this is a known limitation and feature request in the community [[discussion](https://github.com/apache/superset/issues/33105)].
If you need per-user homepage redirects or more advanced sorting, it will require custom code or feature development.

<!-- Answer -->
This error happens because your browser is too old and doesn't support the JavaScript `Set.prototype.difference` method, which Superset dashboards use starting in version 5.0.0. Charts work because they don't use this method. To fix it, upgrade your browser to Chrome 122 or newer (or another browser that supports this feature). Check if the affected network segments are using outdated browsers or have policies that force old versions—updating them will resolve the issue.

<!-- Answer -->
Auto-refresh stops working when you use /?standalone=2 because this mode hides the dashboard header, which is responsible for starting the auto-refresh timer in Superset's frontend. When the header is not rendered, the periodic refresh logic never runs, so charts don't update automatically. This isn't documented as a bug, but is a side effect of how the dashboard UI is structured in Superset 5.0.0 [reference](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L364-L717).
If you need auto-refresh in embedded/standalone mode, the most practical workaround is to use JavaScript in your embedding page to reload the iframe at your desired interval—for example:
```js
setInterval(() => {
const iframe = document.getElementById('superset-dashboard-iframe');
if (iframe) {
iframe.contentWindow.location.reload();
}
}, 5 * 60 * 1000); // every 5 minutes
```
There is no built-in config or parameter to enable native auto-refresh in standalone mode when the header is hidden [reference](https://github.com/apache/superset/discussions/34340).

<!-- Greeting -->
Hi @igarashi-futaba! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team.
<!-- Answer -->
Yes, Superset 5.0.0 supports dashboard previews (thumbnails) on the homepage, but this feature is controlled by a toggle switch labeled "Thumbnails" that appears on the homepage for each user. To enable this, you need to set the `THUMBNAILS` feature flag to `True` in your `superset_config.py` (add `FEATURE_FLAGS = {"THUMBNAILS": True}`) or set the environment variable `SUPERSET_FEATURE_THUMBNAILS=true` before starting Superset. Once enabled, new users will see the thumbnail view by default, but each user can toggle between the list and preview modes, and their choice is saved in their browser's local storage. There is no backend or global configuration to force all users to always see dashboard previews by default without modifying the frontend code.

[@dosu](https://go.dosu.dev/dosubot). In Superset 5.0, can I use an external application (e.g., a custom web page) to submit user credentials (username/password) and pass them to Superset? This would then redirect users to their pre-configured slug-based dashboard after authentication, ensuring each user sees a specific dashboard upon login.

GitHub user igarashi-futaba added a comment to the discussion: Regarding the issues related to the homepage in Superset version 5.0.0
I'm using Superset 5.0.0. Are the permalinks generated through the dashboard's share feature permanently valid and unchanging? Can I create different default homepages for different users by assigning them different permalinks? Additionally, I created a horizontal bar chart with 4 dimensions on the Y-axis. Is it possible to sort the Y-axis by one specific dimension? I've tried various sorting methods, but it seems to only support sorting by aggregated values of dimensions (like max, min, average, sum) rather than sorting directly by the values of a single dimension. The "sort query by" function in the chart menu also doesn't seem to sort correctly.[@dosu](https://go.dosu.dev/dosubot)

Superset 5.0 does not provide a public API endpoint for external applications to submit username/password credentials for login. The standard login flow is protected by CSRF and session management, so simply POSTing credentials from an external app will not work without handling CSRF tokens and cookies as a browser would. After a user logs in through the normal Superset login page, you can redirect them to a specific dashboard using the `next` parameter in the login URL (e.g., `/login/?next=/dashboard/<slug>/`)—this works for redirecting users after authentication, but not for bypassing the login form with external credential submission [source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/views/core.py#L122-L930).
If you want to automate login or integrate with an external authentication system, consider using SSO (OAuth, OpenID, SAML) or the guest token mechanism for embedding dashboards [source](https://github.com/apache/superset/blob/master/superset/security/api.py#L82-L197). For per-user dashboard redirects after login, you can customize the Superset home page using the `FLASK_APP_MUTATOR` config to set a custom IndexView that redirects users to their assigned dashboard [example](https://github.com/apache/superset/issues/34575).
Directly passing credentials from an external app to Superset for login is not supported out of the box and would require custom authentication logic or a proxy that fully emulates browser login, including CSRF handling.

For blank dashboard thumbnails, make sure you have these feature flags enabled in your superset_config.py:
```python
FEATURE_FLAGS = {
"THUMBNAILS": True,
"THUMBNAILS_SQLA_LISTENERS": True,
"PLAYWRIGHT_REPORTS_AND_THUMBNAILS": True,
}
```
You also need to have Celery workers running and a cache backend (like Redis) configured and available. If these are missing or not running, thumbnails will stay blank. If your dashboards only have markdown (no charts), thumbnail generation can fail due to Playwright timeouts—this is a known issue. You can try adjusting screenshot-related config flags (like SCREENSHOT_TILED_ENABLED and thresholds), but they only take effect if PLAYWRIGHT_REPORTS_AND_THUMBNAILS is enabled. Check your worker logs for errors if thumbnails still don’t appear.
[Reference](https://github.com/apache/superset/issues/33132) | [Config details](https://github.com/apache/superset/blob/master/superset/config.py) | [Celery/cache requirement](https://github.com/apache/superset/blob/master/superset/models/dashboard.py)
Superset does not support per-user homepage dashboard redirects out of the box. There is a DASHBOARD_TEMPLATE_ID config that copies a template dashboard to new users and sets it as their welcome dashboard, but this only applies to new users and not as a redirect for existing users.

<!-- Greeting -->
Hi @igarashi-futaba! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team.
<!-- Answer -->
Yes, Superset 5.0.0 supports dashboard previews (thumbnails) on the homepage, but this feature is controlled by a toggle switch labeled "Thumbnails" that appears on the homepage for each user. To enable this, you need to set the `THUMBNAILS` feature flag to `True` in your `superset_config.py` (add `FEATURE_FLAGS = {"THUMBNAILS": True}`) or set the environment variable `SUPERSET_FEATURE_THUMBNAILS=true` before starting Superset. Once enabled, new users will see the thumbnail view by default, but each user can toggle between the list and preview modes, and their choice is saved in their browser's local storage. There is no backend or global configuration to force all users to always see dashboard previews by default without modifying the frontend code.

Auto-refresh stops working when you use /?standalone=2 because this mode hides the dashboard header, which is responsible for starting the auto-refresh timer in Superset's frontend. When the header is not rendered, the periodic refresh logic never runs, so charts don't update automatically. This isn't documented as a bug, but is a side effect of how the dashboard UI is structured in Superset 5.0.0 [reference](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L364-L717).
If you need auto-refresh in embedded/standalone mode, the most practical workaround is to use JavaScript in your embedding page to reload the iframe at your desired interval—for example:
```js
setInterval(() => {
const iframe = document.getElementById('superset-dashboard-iframe');
if (iframe) {
iframe.contentWindow.location.reload();
}
}, 5 * 60 * 1000); // every 5 minutes
```
There is no built-in config or parameter to enable native auto-refresh in standalone mode when the header is hidden [reference](https://github.com/apache/superset/discussions/34340).

You can adjust font size individually for some chart types in Superset 5.0. For example, BigNumber charts have controls for header, subtitle, subheader, and metric name font sizes—look for these options in the chart's control panel, where you can select from values like Tiny, Small, Normal, Large, and Huge. Word Cloud charts also let you set minimum and maximum font sizes directly in their control panel settings.
However, for ECharts (like bar or line charts), Superset does not currently support customizing axis label font size or color through the UI or chart configuration. These properties are set in the frontend code and are not exposed for user override; changing them would require modifying the source code or requesting a feature enhancement from your Superset admin or developers. There is no built-in workaround for axis label font size in ECharts charts at this time [reference](https://github.com/apache/superset/discussions/35775).
BigNumber chart font size controls example:
- `header_font_size`, `subtitle_font_size`, `subheader_font_size`, `metric_name_font_size` (selectable in the chart editor)
Word Cloud chart font size controls example:
- "Minimum Font Size" and "Maximum Font Size" (integer values in the control panel)
[reference](https://github.com/apache/superset/blob/master/superset-frontend/plugins/plugin-chart-word-cloud/src/plugin/controlPanel.ts)
[reference](https://github.com/apache/superset/blob/master/superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/sharedControls.ts)
If you need font size customization for a specific chart type, let me know which one and I can check for available options or workarounds.

In Superset 5.0.0, I'm embedding a Superset dashboard into another webpage using an iframe via the "copy permalink to clipboard" method, and I've set up auto-refresh for this dashboard. When using the permalink directly, the auto-refresh works just like it does on Superset. However, when I append /?standalone=2 to the permalink to hide some UI elements, the auto-refresh stops working. What causes this issue?[@dosu](https://go.dosu.dev/dosubot)
