Hello Helder,
Thanks for your response but it doesn't work.
I use the following lines in the code:
--------------------------------------------------------
device, decomposed=1
LoadCT, 70
mg_horizon,indgen(4600),randomn(seed,12,4600),nbands=6, xstyle=1, ystyle=1
--------------------------------------------------------
I get the following error:
% LOADCT: Table number must be from 0 to 40
Note: You can download mg_horizon.pro from https://github.com/mgalloy/mglib/tree/master/src/vis/lineplo ts
Can anyone help me how I can use the colour table XLOADCT: 70 - CB-RdBu - (shown in http://www.exelisvis.de/docs/loadingdefaultcolortables.html)?
Thanking you once again,
With regards,
Madhavan
