change color of part of a screen

[Jeff Barnes]

Hi Everybody,


I would like to change the background color of "part" of my screen.

In the following screen shot clip, I would like to change the background whenever the waveform dips below the red line. I need to still see the waveform. I can get the screen co-ordinates, I just need to know the color changing part.

Is this possible?

Thanks,

Jeff

Jeff,

If you don't use a dooted red line (use a continuous one) then you can use FloodFill()

Antonio,

Take a look at this second screen shot ... This is an idea of what I am trying to do.

Jeff,

Try drawing a box then use floodFill(). Use the same color pen for both.

Maybe you will have to redraw the gridlines and graph afterward.

Jeff,

Do you mean those vertical gray rectangles ?

[Jeff Barnes]

Antonio,

Yes, the grey areas are what I would like to add when needed.

Jeff,

You may paint them using Rectangle() before painting the lines
