Mozilla plot point size on scattergl plots is not equal as in Chrome and as in SVG plots #1287
Description
I have been doing some trials on my own about scatter and scattergl 2D plots. This is what I found:
SVG plot:
-
Mozilla performs good and exactly the same as Chrome when inputing a list of sizes for the points being displayed. Length(Points) == Length(List of sizes)
-
Chrome performs good an exactly the same as Mozilla in SVG when inputing a list of sizes for the points being displayed. Length(Points) == Length(List of sizes)
WebGL plot:
-
Mozilla performs good but different as Chrome in WebGL and SVG and different as Mozilla in SVG as well.
-
Chrome performs good and same as Chrome in SVG and Mozilla in SVG but different as Mozilla in WebGL
To summarize, at some point the rendering of the scattergl plot in mozilla oversizes the points even if you input a specific point size. Chrome in SVG and WebGL perform the same
Would that be a bug? Would this be solved?
Thank you very much!!

Can you share a reproducible example?

Check out the point size differences between chrome and mozilla running this two codepends in both browsers:
scatter: https://codepen.io/anon/pen/pRjLwL
scattergl: https://codepen.io/anon/pen/dNYmVP
FYI I was using those browsers on UBUNTU 16.04
Chrome: 55.0.2883.87
Mozilla: 50.1.0

In chrome there is a very small difference on point size, but in mozilla there is a huge one with webGL...

Between SVG implementations there is no difference between browsers. So Chrome in WebGL perfomes almost exactly as in SVG, but Mozilla changes a lot... Too much for the app I am doing... and I can't force the useres to use chrome....

Any idea when this could be solved?

FWIW I can't confirm that I'm seeing this. For the
scatterglplot in mozilla 50.1.0 in OS X 10.11.4, I see:So there may be a component of OS or hardware dependency involved.

Thanks for checking @rreusser !

Mozilla 50.1.0 Ubuntu 16.04 SVG plot
Mozilla 50.1.0 Ubuntu 16.04 WebGL plot

@ifll yes, I can confirm the behavior in Ubuntu 16.04
ifll commentedon Jan 10, 2017
It seems to be Ubuntu Specific, as I have checked in windows and it worked...

We use monospace default system font for rendering symbols, it is likely that mozilla has whether different monospace font or uses different rendering approach.
@ifll can you show screenshots of chrome/mozilla webgl plot?

Currently I cannot dedicate some time on it, I need to face other stuff. Maybe during the week or on the next week I can find some time and try to provide them. Sorry for this and hope it is not an inconvinience....
