Hey all, i am making a plot of pitch angle versus Eflux ( eV7sec/cm2/ster/ev) for the data obtained by Wind Spacecraft. it contains 9 plots ranging from high ev to low ev.I am using padplot_both.pro to get it:
my_padplot_both,pd,UNITS='flux',EBINS=[0L,8L]
I wanted to get it in colour, so i loaded the color table with loadact.pro following the above command:
UMN> loadct,39
% LOADCT: Loading table Rainbow + white
UMN> device,decomposed=0
But still I coulnt get the plot in colour. Where am I doing the mistake ?
Will be helpful. thanks in advance !

I also tried this UMN> my_padplot_both,pd,COLOR=13,UNITS='flux',EBINS=[0L,8L]
As COLOR is also a keyword for the routine. But no success.

I tried to define an integer array with the color keyword, but still not helpful.

It is not clear from your question whether you are reloading the image after running loadct
LOADCT will not change the colors of any images that are already displayed.

thank you for the reply ! yes i later learnt that. so the routine i use itself contain a keyword for color. the routine is:
UMN> my_padplot_both,pd,COLOR=13,UNITS='flux',EBINS=[0L,8L]
Here I need to define colour as an array of long/integers specifying the colors associated with each energy bin value. So I tried :
UMN> my_padplot_both,pd,COLOR=INTGEN(39),UNITS='flux',EBINS=[0L,8 L]
But still I couldnt get the rainbow colours. Is the array of integers I defined wrong ?
By the way UMN is the university of minnesota wind software library i am using it in IDL.
