I posted this curiosity at the end of another post:
In retrospect, I suspect it should be its own topic.
I have tried the well-known technique of turning off Preview on the HeatMap component and then feeding this into Custom Preview to try to better control and scale the legend. However, there are two issues:
scale affects the mesh, but not the spacing of the text, and
Custom Preview works in Shaded View in Rhino, but not in Rendered View.
I recommend using the PreviewLW componet from the Human plugin.
Indeed the CustomPreview dowsn’t show in Rendered views. I find the Human component(s) more consistent.
The image below shows the HourlyPlot outputs, but the Heatmap should not be much different.
