jupyter notebook for heatmap snippet, with three options

[opotowsky]

This snippet is for CNERG folk who want to plot 2D heatmaps given x, y, z experimental data. This uses triangulation to form a triangular grid and then applies matplotlib's tricontourf (or tripcolor) to get the surface plot with a colorbar

[opotowsky]

I'm not sure how to request to merge this branch into a branch in the CNERG repo that does not yet exist.

I'm not sure if we've finalized the layout of this repo, but instead of PR'ing to another branch, I would recommend PR'ing to master but with this code in its own directory.

When doing so, also:

• updated the README to describe it better
• the notebook fails when started as-is - I think the data needs the random generation rather than the arange

[gonuke]

Thanks for this addition @opotowsky. I think this approach is particularly useful when your data is on an irregular X/Y grid. There are probably simpler methods for a regular grid.

[opotowsky]

Do I need to worry about configuring anything with CircleCI?

[gonuke]

CircleCI is not ready yet. I am not sure if we have a policy on merging before we get that done, or if we want someone to tackle that first???

[kkiesling]

We need someone to tackle CI before we can (or should) merge anything. I think @bam241 was going to do this (#3)? (not to put more on your plate..) @ypark234 's PR is still waiting too (#1).

[opotowsky]

Great, thanks for catching me up!

[ypark234]

Thanks for follow-ups on this topic, @opotowsky !
Took longer than I thought to revisit #3 as it was not my top priority..
Hopefully #3 gets merged successfully soon and then we can think about what to do with CI on this PR.

[bam241]

@opotowsky could you rebase against main ?

it should trigger the CI.

[opotowsky]

Thanks @bam241 ...done!

[gonuke]

LGTM - thanks @opotowsky
