overplot on the right panel in multipanel figure

[Matteo Ottaviani]

Hi,

I'm pasting below a simplified version of some code I have, where I do not seem to get the Overplot keyword to work correctly. Why is the text not being printed in the right panels, but only in the first plot although I instruct ortherwise? Many thanks in advance to anyone who might help out :)

Hi,

The TEXT function doesn't have an OVERPLOT keyword. Instead, you want to use TARGET to tell it what graphic you want it to appear on:

lambda = [385., 410., 470., 550., 670., 865.]

xleg = 350

p1 = PLOT(lambda,findgen(6), POSITION=[.1,.55,.45,.9], /NoData)

p1a = PLOT(lambda,findgen(6), /Overplot)

leg2 = TEXT(xleg, 0.5, 'a)', /Data, target=p1)

 

p2 = PLOT(lambda,findgen(6), POSITION=[.55,.55,.9,.9], /NoData, /Current)

p2a = PLOT(lambda,findgen(6), /Overplot)

leg2 = TEXT(xleg, 0.585, 'b)', /Data, target=p2)

 

p3 = PLOT(lambda,findgen(6), POSITION=[.1,.1,.45,.45], /NoData, /Current)

p3a = PLOT(lambda,findgen(6), /Overplot)

leg3 = TEXT(xleg, 4, 'item 1', color = 'red', /Data, target=p3)

leg3b = TEXT(xleg, 3, 'item2', color = 'blue', /Data, target=p3)

leg3c = TEXT(xleg, 1, 'c)', /Data, target=p3)

 

p4 = PLOT(lambda,findgen(6), POSITION=[.55,.1,.9,.45], /NoData, /Current)

p4a = PLOT(lambda,findgen(6), /Overplot)

leg4 = TEXT(xleg, 1, 'd)', /Data, target=p4)

Cheers,

p.s. The TEXT function should probably throw an error if you use overplot - I'm not sure why it doesn't...

AAhhh, the culprit! Thanks much, Chris!
