Is there a way to change the color of a line according to the numbers in a different column?
e.g.
A(x) B(y) C(y?, color!)
1 7 1
2 5 1
3 3 1
4 2 2
5 6 2
6 5 3
7 4 3
8 7 3
9 9 4
10 2 4
so that when I plot the line it will begin with color 1 (e.g. black) then continue in color 2 (e.g. red between x=4 and 6, then change to color 3 (e.g. green) between x=6 and 9 and eind with color 4(e.g. blue)
Best would be a way to have the colors follow the rainbow colors as in a contour plot

This works great.
now I would like to use a rainbow color list that stretches between min and max values of the color column list. I.e. in a way as you can do it with the z-values in a contour plot.
I see that I can select a rainbow color palette (system color list), but it is fixed to 13 color values.
is there a way to use a color palette that will stretch with a given step width or a given number of steps between the min and max value of a given color column list?
Also I would like to show a vcolor legend on the graph indicating color and corresponding color column entry.

Hello,
You can double click the plotted line and go to Line tab of Plot Details dialog. Click Color control and choose By Points tab.
You can choose Indexing: Col(C). Then Color List tab will show in Plot Details dialog for you to specify what color is for 1, what color is for 2, etc.
Or you can choose Colormapping: Col(C).
Then Colormap tab will show. Click Fill column header and choose Load Pallette. There are many built-in palette such as Rainbow.
You can press F1 in this dialog to see Help.
Thanks, Snow |
