Webviewer Night Mode

Hi, is it possible to change the webviewer component to night mode. I am trying to use the chartmaker extension, which plots a graph, but always in white back ground. So, I would like to know, if there is anyway to make it in nightmode.

The chartmaker extension is based on google charts (gviz) but there are no formatting elements for the chart background in the extension. You would need to build your own charts using gviz to get that functionality:


Thanks for your reply. Is there any example of someone doing this using gviz?
