jquery flot pie left outside border when printting to pdf

Question

I am using "wkhtmltopdf" in order to print an html report. This html contains a pie-chart jquery chart.

This html works perfectly fine.

In the other hand the printting seems to go alright buth when i check the ouput pdf the pie charts leaves some kind of circle around the chart. As you may see in the image.

Thanks a lot in advance.

Answer 1

I did not solved it but i got and improvemente by changing the donut chart for a pie chart.

And also by reducing the margins between the sections of the chart.

stroke: { color: '#fff', width: 0}
