Component request: Heat map

[LoicUV]

Hello! As I need a heat map type of chart for a project, I was wondering if some work had already been done regarding this, and if not try to implement it.

We can discuss the requirements here.

Here's a concrete example of how it would look in my project:

If it's useful, I recently implemented a color heat map in my own library, feel free to borrow code:

https://github.com/spotify/reactochart/blob/0.2.1/src/ColorHeatmap.js

(it's still a rough draft, needs to handle categorical axes better)

Super useful. Thanks @dandelany

+1 for heatmap 😃

@boygirl Are there still plans to create this chart type? Thanks!

any news about that?

[boygirl]

Yes! this is the next big thing I'm planning to work on. It will build on the histogram feature we released recently

Notes: This component will be basically a 2d histogram, and this work will involve updates / improvements to VictortyHistogram. Work will also involve enhancement of the colorScale prop or the addition of a new colorBy prop to support heatmap coloring. Work is in progress, but interested parties should reach out with API opinions.

Any updates on this? I'd really like to use a heatmap.

@becca-bailey I see you guys have an initial implementation of heatmaps in victory charts but didn't get that over the finish line. We would like to have them included as part of the victory charts so we can use them. Is there a way we could help you guys to get this task finished?
