Creating a jpeg file from a colored plot [message #78127]

Hello all,

I have three victors and I want to plot them in a colored plot and
save them as jpeg image. The three vectors are v1, v2, v3.

I did the following:

Device, decomposed = 0

R = [0, 1, 1, 0, 0]
G = [0, 1, 0, 1, 0]
B = [0, 1, 0, 0, 1]

Tvlct, R * 255, G * 255, B * 255

Plot, v1, background = 255, color = 0
Oplot, v2, color = 2
Oplot, v3, color = 3

So, I got a colored plot with three lines, v1, v2, v3. After that, I
wanted to save the plot as jpeg file. Thus, I did the following:

im = tvrd()

Write_jpeg, ‘filename’, im

And the final result was a black and white jpeg image plot with the
black line only (v1). My question is that how can I save the plot as
colored jpeg image with all the plotted vectors.

Your help is appreciated,

MD
