[ferret_users] aline colors

[Derek Tsui <i.am.mr.sleepyhead@xxxxxxxxx>]

Dear Ferret Users,

 

I am trying to draw grid lines using ppl aline, however I can't seem to control the line colors. I am trying to get a grey line color. I've looked at ppl pen and ppl color but was unable to find such color. Does anyone have any idea how I can draw grey grid lines?

 

Thanks,
Derek
