[feature request]: 2D plots
Closed this issue · 3 comments
Following up on the comment made on https://stackoverflow.com/questions/50820894/filling-numpy-arrays-slower-than-for-loop-h-fill-vs-h-fill-numpy:
It would be good to replicate 2D plots that are common in HEP like the on http://histogrammar.org/docs/tutorials/python-matplotlib/
Vega-lite has a scatter plot as well as a heatmap (and table binned heatmap):
- https://vega.github.io/vega-lite/examples/point_2d.html
- https://vega.github.io/vega-lite/examples/rect_heatmap.html
- https://vega.github.io/vega-lite/examples/rect_binned_heatmap.html
The latter is probably closest to what we need.
I was just about to create a request for 2D plots ... :)
So let me second this one.
It's in the enhancements branch. Try it out and let me know if it's missing anything.
I haven't done the 2D export to ROOT yet, though.
Oh, the new method is Hist.heatmap() or Hist.heatmap("x", "y"). The documentation won't propagate through to readthedocs until I merge enhancements to master.
