[D] Calendar Heatmap Not Emitting Cross-Filters to Table Chart [superset]
GitHub user Nagarajkalasagonda created a discussion: Calendar Heatmap Not Emitting Cross-Filters to Table Chart
### Bug description
**Description:**
I am experiencing an issue where my Calendar Heatmap chart in Apache Superset (version 4.0) is not emitting cross-filters when clicked, preventing a linked Table Chart on the same dashboard from updating.
The goal is to click a day cell in the Calendar Heatmap (which shows `COUNT_DISTINCT(change_request_id)` by `planned_start_time` at a daily grain) and have an adjacent Table Chart filter to show the raw records for that specific `planned_start_time`.
**Observed Behavior:**
When a cell in the Calendar Heatmap is clicked:
1. No filter is applied to the dashboard.
2. The linked Table Chart does not update.
3. The browser's developer console (F12) remains completely silent, showing no errors, warnings, or network requests related to filter emission or data fetching.
**Context / Environment:**
* **Apache Superset Version:** 4.0
* **Database:** : Starrocks - Iceberg
* **Dataset:** `demo_dn_ut2.mart_cm_...`
**Steps I Have Followed (and Verified):**
1. **Global Cross-Filtering Status:**
* Confirmed that `DASHBOARD_CROSS_FILTERS` feature flag is enabled in `superset_config.py`.
* Verified that cross-filtering works correctly on *other* dashboards with different chart types (e.g., Bar Chart -> Table Chart).
2. **Dataset Configuration (`demo_dn_ut2.mart_cm_...`):**
* **`planned_start_time` column:**
* Verified its data type in the dataset definition is `DATETIME` (or `DATE`/`TIMESTAMP`).
* Confirmed "Is temporal" checkbox is checked.
* Confirmed "Is filterable" checkbox is checked.
3. **Calendar Heatmap Chart Configuration (e.g., "Test change"):**
* **Chart Source:** `demo_dn_ut2.mart_cm_...`
* **Time Column:** `planned_start_time`
* **Query Domain:** `month`
* **Query Subdomain:** `day`
* **Metric:** `COUNT_DISTINCT(change_request_id)`
* The chart renders correctly and shows data as expected.
4. **Table Chart Configuration (e.g., "Test change Calender"):**
* **Chart Source:** `demo_dn_ut2.mart_cm_...` (same dataset as heatmap).
* **Query Mode:** `RAW RECORDS` selected.
* **Columns:** `change_request_id`, `planned_start_time`, `log_date`, etc., are listed as raw columns (no aggregation or grouping applied to `planned_start_time`).
* **Time Section:** No specific Time Column or Time Grain selected, or set to "No filter" / "Raw" to allow for granular filtering.
* **Removed** any persistent filters from the Table Chart's configuration.
* The Table Chart renders correctly and shows all raw data.
5. **Dashboard Configuration:**
* Both Calendar Heatmap and Table Chart are placed on the **same dashboard**.
* Dashboard is in **Edit mode**, and the global **`Cross-filtering`** toggle is **ON**.
* Inspected individual chart properties on the dashboard:
* Calendar Heatmap: Confirmed it's set to "Emit filters" or "Apply to all charts" (if such options are available).
* Table Chart: Confirmed it's set to "Respond to filters."
* Saved all dashboard changes.
6. **Troubleshooting Attempts:**
* Performed hard refreshes (Ctrl+Shift+R) of the browser.
* Monitored browser console (F12) during clicks: No errors or warnings appear. No network requests are initiated for filtering the Table Chart.
**Issue Still Facing:**
Despite all configurations appearing correct and cross-filtering working elsewhere, the Calendar Heatmap chart still does not emit filters when its cells are clicked, and the Table Chart remains unaffected. This suggests a potential limitation with the Calendar Heatmap visualization type itself regarding filter emission.
**Proposed Resolution (if applicable):**
(You can add this if you have a specific hypothesis, e.g., "Requesting confirmation if the Calendar Heatmap chart type in Superset 4.0 is indeed designed to emit cross-filters, or if there's a specific setting I'm missing.")

Indeed, this is one of a few charts that do not emit crossfilters. You're welcome to open a PR to address this, or we can move it to a Discussion if you want help from the community here.

We do not have a community kanban with target dates for smaller features/fixes... but I think that's the nature of open source.
One thing to confirm here is that you're using the newer (ECharts-based) Heatmap viz, and not the _legacy_ Heatmap. The ECharts one _could_ be improved to add cross-filter emission.
The other ECharts viz plugins already do emit these so you could look at their code to see how they do it and open a PR. We'd be more than happy to review it! If you need professional services to get this done on a certain schedule, you can DM me on [Superset Slack](http://bit.ly/join-superset-slack) to talk about that.

@rusackas Can we move it to community for discussion of this point. I have requirement which such as on particular date how many and which all changes are planned so that it will be helpful for me to plan better. So any other suggestion from community I am open with.
