Hi seafree,

I start with the Simple Line Chart sample code:

https://www.advsofteng.com/doc/cdperl.htm#simpleline.htm

I changed the data to include both positive and negative numbers:

my $data = [30, 28, 40, 55, -75, -68, 54, 60, 50, -62, -75, 65, 75, 91, 60, 55, 53, -35, -50, -66, 56, 48, 52, 65, 62];

I can successfully produced the attached chart. The chart looks OK to me.

If you think it does not work in your code, is possible to provide an example that I can run, so I can test it and trouble-shoot it?

Best Regards
Peter Kwan
