new markers (star, hexagon...) available in ScatterPlot but not in ColormappedScatterPlot

[fred4ets]

Hi there,

New ScatterPlot markers as star, hexagon, hexagon2, pentagon and so on are not available with ColormappedScatterPlot.

For instance, if you run Chaco demo example scatter.py in basic/, it works well if you change line
"marker='circle'" by "marker='star'".
But if you run basic/cmap_scatter.py with the same modification, it displays... nothing.

So my question is : could it be possible to implement these new markers in ColormappedScatterPlot please?

Thanks in advance,

Cheers,

Hi, thanks for the report. I have a suspicion as to where the issue may be.

Can you try setting render_method = 'bruteforce' on the colormapped scatterplot to see if that makes a difference in your case?

Hi Corran,

I tried your hint.
But there is no difference.

Thanks for the feedback - that means that the issue isn't what I thought it might be.

Hello @fred4ets, I've just opened #672 which I believe should fix the issue. I was able to use marker="star" on basic/cmap_scatter.py locally.
The problem seems to have been enable/chaco being out of sync on what markers work with what methods. The PR is not finished yet. Ideally it will include a regression test, and I think the solution is unideal. It could be made more robust by not hard coding the specific markers for which we can't call draw_marker_at_points. I will update it soon.
In any case, a fix should be made in the near future!

Thank you for reporting this issue!
