  1. Create a heatmap plot with about 500 x 500 elements
  2. Configure the plot with scrollZoom = true and zsmooth = 'fast'
  3. Use the mouse wheel to zoom in rapidly into the plot

Result:

  • the plot is not zoomed in and the console displays "Uncaught RangeError: Invalid array length"

The array being created is the pixel array in which to draw the interpolated heatmap at traces/heatmap/plot.js:238

The problem seems to be that imageWidth and imageHeight are used here and later in the function, perhaps instead of canvasW and canvasH.

                              1. Create a heatmap plot with about 500 x 500 elements
                              2. Configure the plot with scrollZoom = true and zsmooth = 'fast'
                              3. Use the mouse wheel to zoom in rapidly into the plot
                              Result:
                              • the plot is not zoomed in and the console displays "Uncaught RangeError: Invalid array length"
                              The array being created is the pixel array in which to draw the interpolated heatmap at traces/heatmap/plot.js:238
                              The problem seems to be that imageWidth and imageHeight are used here and later in the function, perhaps instead of canvasW and canvasH.
