[GitHub] [superset] kamalkeshavani-aiinside opened a new issue #16271: [charts] Keep similar features across all charts

kamalkeshavani-aiinside opened a new issue #16271:
URL: https://github.com/apache/superset/issues/16271

**Is your feature request related to a problem? Please describe.**
Currently there are many charts with different kind of features. Ex.,
1. Line Chart can add a title for X-axis but Mixed Time-series cannot.
2. Bar chart can show values in chart, but line or area charts can not.
3. I can have different formatting in tooltip only in Time-series chart.

When our end user see one feature in a chart, they expect to be able to use the same feature in all other charts. But due to this limitation this is not possible right now.

**Describe the solution you'd like**
There should be guidelines for every chart type for all the types of controls/features available to the user for that chart based on its type.
Here are some I could think of, but clearly more should be added by contributors and maybe even community can add their suggestions.

**X-axis:**
1. Add title
2. Show bounds
3. Set bottom margin
4. Set tick layout
5. Reduce X ticks
6. Show/hide Major-minor gridlines
7. Set minor ticks and gridlines granularity
8. Value formatting

**Y-axis:**
1. Add title
2. Show bounds
3. Set bounds
4. Set left/right margin
5. Set tick layout
6. Reduce Y ticks
7. Show/hide Major-minor gridlines
8. Set minor ticks and gridlines granularity
9. Value formatting
10. Make logarithmic axis

**Tooltip:**
1. Set new formatting for all values, and default to formatting of each axis(This is helpful when we want to keep chart clean, but show more accuracy/decimal points in the tooltip)
2. Set Rich Tooltip
3. Chose to show null values in Rich Tooltip
4. Show total or % distribution in Rich tooltip if possible

**Line Chart:**
1. Show markers
2. Change marker size
3. Show values on points

**Bar Chart:**
1. Set Stack or Group
2. Set order of bars in stack or group: by metric order, by group by element value, by group by element alphabetical, by another metric
3. Show bar values on top/center
4. Show total bar values when stacked or individual bar values
5. Set minimum width of a bar
6. Set minimum distance between bars when grouped

**Area Chart:**
1. Change opacity of area
2. Show markers
3. Change marker size
4. Show values on points

**Additional context**
I guess that no re-work can be expected on legacy charts, but the least I can expect is to start following such guidelines for the new echarts.
And if making this possible is not very hard, I would really appreciate doing the changes(atleast the easy ones) in legacy charts as well, since they will be used for some more time(until advanced analytics are enabled for echarts).
