[9fans] Using plot(1)

[Chris McGee <newton688@gmail.com>]

Hi All,

I’m trying graph and plot out. I have some questions.

Is there a way to pipe the output of plot or do I need to pull that out of the screen/window buffer? Also, is there a way to plot on top of an existing image?

I tried making a simple plot routine to draw a red unit circle with x and y axes. The lines are drawing fine, but the circle is completely cut off except for a hint of the top-most and bottom-most edges. Here’s the routine that I’m using. Is there something obvious that I’m doing wrong?

co k

li -1.0 0.0 1.0 0.0
cl

Thanks,
Chris
