Negative --yrange doesn't work #50

MarekKnapek commented 3 years ago

I would like to adjust yrange. When I try your sine example, I can do it for a positive numbers such as from 0.5 to 1.0 but when I try with negative numbers, such as from -0.5 to 1.0, your program fails. I'm on Windows 10 x64, using Python 3.9.4.

>graph sine.csv --yrange 0.5:1.0 -o sine.png

>graph sine.csv --yrange -0.5:1.0 -o sine.png

Please try using the equal sign syntax. --yrange=-0.5:1.0

Works great. Definitely should be mentioned in manual and in examples.
