I am using flot to generate graphs in my application. The graphs are rendered correctly. The web page is then converted to a pdf using PDFKit. On conversion, the coordinates[X,Y] of the graph are displayed correctly While the graph itself is not rendered.
Problem seems to be with the canvas tag-
<canvas class="base" width="600" height="300"></canvas>
<canvas class="overlay" width="600" height="300" style="position: absolute; left: 0px; top: 0px;"></canvas>
Any clues on which direction to look to solve the problem will be very helpful.
PDFKit uses wkhtmltopdf to do the actual rendering right? So you might need to dig into PDFKit and make sure it's specifying the right options for wkhtmltopdf, specifically
--redirect-delay <time> might be useful.
