I have a very similar temperature monitoring graph to this one:
https://calomel.org/rrdtool_health.png ..and technically I'm pleased
to it, but I would like to change the background image of the graph.
How to achieve this? Which techniques might be used in order to add
logos or different backgrounds to graphs?
