Oddly aline doesn't change colors even after defining the color, but plot works great. Thanks!!

Hi Derek -
Define a gray color with equal values of R-G-B. For example:
ppl color,5,40,40,40
That will redefine pen color 5 (cyan) to be light gray.
But ALINE can be flaky. I would just use plot/over:
plot/vs/over/nolab/line=5 {7,10},{4,4} ! draw a line on a plot with defined-on-the-fly values
You could do this in a repeat loop to draw a grid.

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
