Hi
I am using the cgimage function to display my images. I draw the axis on top of my images, but I don't want the axis to be labelled. I used the following code
cgimage, Im1, /AXES, AXKeywords={XTicklen:1.0, YTickLen:1.0, axiscolor:'blue', xminor:1, yminor:1, xtickinterval:30, ytickinterval:30}, /SAVE,Position=pos[*,0]
I tried the XTICKFORMAT keyword but is not allowed to the cgimage function.
How can I turn axis labelling off? Can anyone please help with this?

I use [x,y,z]tickname to suppress labeling of axis. I never used them with CGimage function.
Set [x,y,z]tickname to a string array with same size as the number of ticks in that axis. Element of string array should be a SPACE Eg.
x=fltarr(256,256)
plot_image,x,xticklen=replicate(' ',6),yticklen=replicate(' ',6)

Sorry, there is a mistake. It should be
plot_image,x,xtickname=replicate(' ',6),ytickname=replicate(' ',6)

You can do it via the tickname keyword (like Valibhav said) or tickformat.
cgimage, Im1, /AXES, AXKeywords={XTickFormat:'(A1)'}
