I’m wondering if someone can guide to an idea, the algorithm, an example of how to create Power BI’s symmetry shading for scatter charts (https://learn.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-scatter?tabs=powerbi-desktop#add-analytics-to-your-chart)

I would like to know if it is possible to to bind a sort order and sort field to a parameter.
Id like to allow users to select from the option lists which field and what sorting order they would like to sort the visual.
for example, I have a bar chart that show CY and PY value, so the users can sort CY Descending by using the option.

How can I fix the widths of visuals when concatenated with hconcat in Vega Lite such that they don’t move when filtering?

With text marks on stacked bar charts, is there a way to avoid duplicating the tooltip code so that the tool tip is the same when hovering over the text marks?

If I concatenate multiple visualisations, is it possible to change the spacing between them easily?

In Vega-lite it is possible to assign a parameter to the legend (see example video here). Is it also possible to assign parameters to the axis labels? I know this is possible in Vega with signals from a previous question.
