jqplotToImageStr - strange behavior

[FredVeuerstein]

Can you please help me?
jqplot makes a fine plot as shown in firstly attached image correct.png. Lable 'Volumenstrom..' and ticks on x-axis are correctly plottet.

Now, i want to save this graph as image.

Crome 67.0.3396.99 (Offizieller Build) (64-Bit) and IE 11.096 show a fine image as expected, each detail as in original, correct plot.

Firefox (Quantum 61.0 (64-Bit)) shows the secondly attached image

The lable 'Volumenstrom..' is disappeared, no labeling and no ticks are on the x-axis, the y-axis is stretched into a little 'nirwana'.

What's going wrong in FF or what am i doing wrong?

some codesnippets:

<script> var plot2; $(document).ready(function(){ var series1 = ; var series2 = ; var labels = ; var data =[series1, series2]; plot2 = $.jqplot ('p_kenn', data, { .... var imgData = $('#p_kenn').jqplotToImageStr({}); var imgElem = $('

').attr('src',imgData); $('#img_p_kenn').append(imgElem); ...

Hi @FredVeuerstein

Thanks for raising this bug, I have attempted to replicate the issue but I am having some trouble.

Can you please submit some for specific information, such as the options plugins used. A copy of the $.jqplot initialisation statement should be sufficient, although the more detail you can provide the better.

Hallo Daniel,
please accept my apologise for my late answer.
My father died, i had to move to another town. So i vergot my troubles with jqplot.

After hours of testing, the situation is now:
Your examples on your homepage is working well. i mentioned a small discrepancy, your examples are completly hosted inside php-files, in downloaded file, all examples are hosted in html-Files.
i downloaded latest version of jqplot (jquery.jqplot.1.0.9.d96a669.zip).
i expanded the zip-file in an empty directory. i didn't change any line inside.
i started line-charts.html in example-directory with doubleclick in filemanager.
Anything was going well.
Then i pointed to line-charts.html in my latest Firefox 64.0 Quantum, running offline an apache 2.4 inside XAMPP Version: 5.6.28.
The result, similary in all plot-images with ticked and labeled x-axis/y-axis is shown in the appended picture, same behaviour as above picture.

The strange behaviour is only to be seen in Firefox (also in one or two former versions), not in Chrome 71.0.3578.98 or IE 11.0.9600.18499
(only Windows-Firewall running, uBlock deactivated.)
i am running Windows 7 prof. SP1 64 and i am at a loss with that behaviour. Do you have an idea?
