heatmaps don't respect axis categoryarray

[hellochar]

Hey Plotly,

It looks like you can use axis.categoryarray to reorder the bars in a bar chart. I'm trying to do the same thing with heatmaps (that is, reorder the heatmap columns) but it only seems to change the tick labels, not actually move the data. See http://codepen.io/hellochar/pen/WGBEow . This is concerning since the data being displayed is not longer accurate to the data that was fed in.

Is there another way to specify the heatmap ordering, other than by modifying the x/y arrays manually?

Thank very much for the report.

any plans to fix it?

yes, that's what the type: bug label means.

Still need to write test and support multicategory

Looking good @antoinerg - thanks for taking this on!

@etpinard About multicategory axes, it seems like categoryorder isn't implemented for it (#3723 (comment)). I will not tackle this here.

Yes, that's correct. My bad!
