auto bins and cumulative distribution histograms

[alexcjohnson]

We need a way to harmonize autobins across traces, and that it needs to know about cumulative. To make this example work I needed to manually extend the bin range for the red trace, otherwise its CDF ended too soon. Actually, CDFs never end, really... so perhaps the even better thing to do would be to look at the axis range and draw bins out to the edge, while still only using the real data for autoranging? We also need to make sure bin sizes and edges match, which is needed for non-cumulative histograms as well.

Is this now closed?

Update:

From the hist_cum_stacked which sets xbins: {start: 0.5, end: 10.5, size: 1} in both traces

then clearing xbins we get:

which computes shared bins (post #3044) of:

gd._fullLayout._histogramBinOpts.xyx = {
  end: 13.5,
  size: 2,
  start: -0.5
}

That is, the default auto xbins essentially have one bin too many. So I'd leave this issue open.

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
