Hi Sebastian

This page has some good examples


In short I don't think you can mix none strftime variables and strftime variables so in your example

GPRINT:tmax:"max %0.2lf":"%H"

would need to be (using Perl)


Putting %0.2lf would result in "%0.2lf" being printed literally.

My graph definition (snipped)

GPRINT:tmax:"max %0.2lf":"%H"

I get: ERROR: I don't understand ':%H' in command: 'GPRINT:tmax:max
