I have try dpi:96, also 90, and also another value, with the same result.
I have put my log to verbose. With or without format_option, I have an
interesting Exception :
java.lang.NumberFormatException: empty String

(The full trace is long of 180 lignes, but we can see the call of ChartEngine
here).
Without format_option I have this trace just once.
With format_option, twice.
Thank for all.

First up, 35 dpi is … very low!
I am not so familiar with the chart code, do you have any kind of stack trace
or other information beyond not showing the charts? Can you try with dpi:96
(matching the usual WMS default) so we can see if it is the format_option being
applied at all, or just such an unusual number which is breaking the chart
support.

Hi,
I use the charts extension in my geoserver instance.
https://docs.geoserver.geo-solutions.it/edu/en/pretty_maps/charting.html
I use some variables substitutions in my OnlineResource.
If I make a GetMap request, no problem.
But if I make a GetMap request with the DPI format argument
(format_options=dpi:35), the result is broken. Not show the charts.
If there are no variables substitutions, no problem ; but I need my variables
substitutions.
Do you know any solution ?
Thank you
