Add Numbers to heatmap #22

Closed robinfallegger closed 7 months ago

robinfallegger commented 7 months ago

Thank you so much for this amazing package!

I am not sure if this might already be possible with the current version, but it would be amazing if instead of adding markers to a heatmap, we could display the actual values on top of the heatmap.

Thanks a lot!

Thanks for using Marsilea!

There are two ways to achieve this:

  1. Pass annot=True to Heatmap, this is the same as seaborn.
  2. There is a hidden plotter called TextMesh (not documented yet), you can use .add_layer() to add TextMesh on top of the heatmap, this will give you finer control over the style etc.

I'm trying to improve the documentation these days, feel free to ask questions or give suggestions!

@Mr-Milk Thanks so much ! The TextMesh solution worked perfectly.
