I'm trying to draw a bar graph in Revolution using values from an
array. I use the following code, repeated for each bar, to draw the
graph:
create invisible graphic
set the style of it to rectangle
set the opaque of it to true
set the rectangle of it to startY,tDrawX,tDrawY,startX
set the foregroundColor of it to "#000000"
set the backgroundColor of it to "#9198A0"
set the lineSize of it to 1
show it
This all works very well, but the next time I come to draw the graph,
the old rectangles are still sitting there. How can I get rid of
them?
Have a loop at the start of your drawing routine that goes through and
deletes them all. If you have no other graphics, you can do:
repeat the number of graphics times
delete graphic 1
end repeat
If you have other graphics that shouldn't be deleted, then I suggest
you name your chart graphics as they are made, and do something like
this:
repeat with x = the number of graphics down to 1
if the short name of graphic x contains "Chart" then delete
graphic x
end repeat
HTH,
Sarah
Thanks very much for the very prompt reply Sarah :-) - I do have some
other graphics so I'll need to go the second route.
Thanks again,
Karen
