Hello all,
When I open a plot using cgwindow and display text using cgsymbol on that plot, and then save to a pdf using the cgwindow drop down menu, some of the symbols change.
For example, cgsymbol('sigma') gives the correct sigma symbol on the pop-up cgwindow, but converts to an 'r' in the saved pdf. cgsymbol('sigma', /ps) gives the wrong symbol in the pop-up window, but the correct symbol in the pdf. I need the symbol to be correct on both as I am using both and cannot have a difference in readability.
Any solutions?(Using a mac, if it matters).
Small illustrative example:
cgwindow, 'cgplot', indgen(100), /xstyle
cgwindow, 'cgtext', 20, 70, cgSymbol('sigma'), /data, /addcmd
-->save to pdf, sigma becomes an 'r'.
cgwindow, 'cgplot', indgen(100), /xstyle
cgwindow, 'cgtext', 20, 70, cgSymbol('sigma', /ps), /data, /addcmd
--> displays a lower-case sigma in 'word-final position' instead of the standard lower-case sigma on the cgwindow, and in the pdf it is displayed as the intended sigma symbol.
Thanks,
AJ

This is a limitation of the way Coyote Graphics has to work to
"recreate" the command when things are redrawn. You can't actually call
a function from within the command you are trying to "recreate", since
there is no actual command stack.
To get what you want, you can write a routine like this:
pro main
cgplot, indgen(100), /xstyle
cgtext, 20, 70, cgSymbol('sigma'), /data
end
And call it like this:
IDL> cgWindow, 'main'
Cheers,
David
