Multiple issues with transforms

I’ve been trying to add transforms to multiple trace types with varying degrees of success. Documentation doesn’t make it clear which trace types support transforms. All I know from discussion with @etpinard, is that anything that takes 2d arrays as input doesn’t support them. react-chart-editor as of now does not prepopulate target/targetsrc:

      "transforms": [
        {
          "type": "filter",
          "target": [],
          "targetsrc": null
        }
      ]

Results:

scatter3d:

• filter: many warnings: [.Offscreen-For-WebGL-0x7fef4b0d6800]RENDER WARNING: Render count or primcount is 0.

-> https://codepen.io/etpinard/pen/dgWJZg

scatter3d + marker:’line’

• filter: Uncaught (in promise) TypeError: Cannot read property 'slice' of undefined at LinePlot.proto.update

-> https://codepen.io/etpinard/pen/Edmobo

cone, streamtube, scattergeo, table, heatmap (with 1d array input), contour (with 1d array input)

• any transforms: as I add them to data, they never get added to fullData

choropleth, scatterternary, scatterpolar, pie:

• aggregate: Error while plotting: TypeError: Cannot set property 'type' of undefined at Object.plots.supplyTransformDefaults

pie:

• filter: Error: <path> attribute d: Expected number, "MNaN,NaNa189.5,18…".

-> https://codepen.io/etpinard/pen/wYdppB

2d contour histogram:

• filter: Error while plotting: TypeError: Cannot read property 'length' of undefined at makeCrossings (plotly-with-meta.js?ab3a:146042)

Edit: Add this one to the list:

• When defining a scatter with just Y defined, and than add an aggregate: Uncaught TypeError: Cannot set property 'type' of undefined at Object.plots.supplyTransformDefaults https://codepen.io/dmt0/pen/xJoWoY

This one got fixed in: #3093

As far as I can tell, @antoinerg 's https://github.com/plotly/plotly.js/pull/3158 removed the transforms attribute container from all traces that do not support transforms.

scatterpolar now looks like:
