Hi Richard

I have designed a instrument panel with semicircular progress.
Some users reports me the semicircular was not drawn correct with firefox. But on my pc i can't simulate it. On my pc it's ok.
But when i simulate in on browserling i can see the failure.
Look here: www.browserling.com/browse/win/7/ie/11/http%3A%2F%2Fwww.awekas.at%2Fde%2Finstrument.php%3Fid%3D11790
... and switch for firefox 53
Until Firefox 48 it works well - Firefox 49 and later did not work properly!
Can you please check it. Thanyk you.

Regards Othmar

Hi,

I assume that you're referring to the missing label. I don't get the issue in my FF browser, but FF did used to not render any text at all - so maybe it's connected to that.

You could try enabling accessible text and the chart will try to use DOM text instead of canvas text.

textAccessible: true,

Hi Richard

tectAccessible: true did not change anything. If i select the not shown text, the hidden text was displayed.

Any idea? This bug is only at the Semicircular. All other are ok.

Hi there,

Are you setting it on ALL of the RGraph objects (including the drawing API objects)? The URL appears to have mixed accessible text and canvas text.

Hi Richard

I can set it only for the graph panel. The Line graph below will not work properly if i change it to tectAccessible: true.
(This was a question some time ago - you tell me i have to set it to tectAccessible: false ;-) )

Hi there,

I don't know what it is then I'm afraid. It sounds like FF issue with rendering text on canvas.
