Customize Heatmap Hoover

Hi plotly team,

I have a heat map and the hoover always shows labels X,Y,Z. Is there some way to customize this labels and put my own? The problem is that I have a huge data set and I don’t want to make trace(s) only for hoover purpose.

Try setting the text attribute in the trace together with hoverinfo: 'text'.
