In Plotly, can I have customized hover text in a heatmap?

Question

I noticed that in some graph types, there is a "t" argument that will allow customized hover text. This argument seems to be missing from the heat map API. Is there another way to implement it? I would like to have actual informative labels instead of "x:", "y:" and "z:".

Answer 1

The t key is not currently supported in plotly heatmaps, unfortunately.

The t key is now available for heatmap and contour trace types.

Here's an example of a heatmap with hover text: https://plot.ly/~etpinard/2096/heatmap-with-hover-text/
