The valid value of opacity

[Erimus-Koo]

I have some questions about the opacity

• I set column "weight" as opacity, there are 2 values in this col, 1 and 255.
• A sample line in my df is {'name':'some name', 'month':'2022-02', 'weight':255}, name as Y and month as X, and weight means the opacity of the cell such as a heatmap.
• If this col is "dimension", then drag on opacity, it looks fine. But if set as "measure", it looks been calculated for the whole column.
• And even if I set the weight from 10 to 100, or 1 to 255, or 0.1 to 1, the opacities look the same, is it some normalization happened? Can I set a specific value for the opacity?

As a new feature, there might be a way to set the domain ([min, max]) of a certain channel or a quatitative field in the future. Details about interaction are under discussion now.
