We want to show live graphs from PRTG in our NOC screens but need them to have a different background color. How can I do this?
Can I set the graph background color of PNG graphs in PRTG?

There are two possibilities to control the color:
1. In order to set the color of all graphs created by PRTG please edit the system settings. Detailed instructions are in the manual of PRTG 8:
https://www.paessler.com/manuals/prtg8/system_website_settings.htm (search for "Background Color for Graphs")
2. If you are using PNGs files in your own web pages using PNG-URLs you can control the background color using the bgcolor parameter.
Sample URL:
http://10.0.0.157/chart.png?type=graph&[....]&bgcolor=%23ff0000The bgcolor parameter must contain a CSS style color code, e.g. #000000 for black, #ffffff for white and must be URL encoded (# is converted to %23)
Note: Option 2 is implemented in PRTG 8.1.2 and later
