Draw with pencil tool from a script to produce wiggly line?

I want to draw a line graph from a script.
I have an image area which I can write on using the mouse, but cannot move the pencil tool from a script and hence produce the graph line. I remember doing this in HyperCard.
Of course there may be another way of doing this ... suggestions welcomed
Thanks

Hi Geoff,
try this:
Code: Select all
on mouseUp
choose pencil tool
drag from "10,10" to "100,10"
end mouseUp
And replace the coordinates with yours.
Tested and works
Best

Thanks Klaus. I did try drag from .. to ... but couldn't get it to work earlier. Now it's OK.
You don't happen to know how to clear an image do you?

Ah, ha ... tried this and my background colour disappears!
and
set backgroundcolor of img "my image here" to "White"
doesn't do anything.
Hmmmm .... setting the 'second color' in the object inspector doesn't change anything either ... it's not obvious what I doing wrong ... or is it?

Hi Geoff,
well your question was how to clear an image, and that's what my line does completely emptying the image
Sorry, I don't think you can clear certain parts of your image.
Maybe you can try an "undo" right after the last editing?
I'm not sure, but its worth a try:

Ah yes, if you only need the backgroundcolor in your image...
