Scatter plot with different marker ? #1706

Closed sczesla closed 4 months ago

sczesla commented 4 months ago

As far as I can see, only circle markers are possible in scatter plots.

Different markers may be useful to distinguish individual quantities.

My actual idea was to build a heat map out of "square pixels" using a scatter plot, which could also take advantage of the tooltip to show quantitative information. Is there already way to do this?

You can customize your marker by the dotPainter property, Please take a look at the Scatter Sample 2
