Uh. I did look at the code (I DID download it), but finding no objects
in the main routine I got disappointed :-)
The simpliest thing that occurres to me to connect symbols with lines is
to plot the data twice with PSYM and without. However, I find it strage
that negative PSYMs are not honored by the program as it seems straight
forward through keyword inheritance.
In the view of these shourtcomings from The Expert, I dare to offer the
updated (recently updated, namely last friday) DISPLAY.
http://www.ainaco.com/idl/idl_library/display.pro
Additions:
1. Use of DISPLAY as main graphics child in a widget program improved;
plots replacement is enforced unless /OVER is used.
2. Text positioning and dragging with the mouse improved in both data
coords (scalable) and on-glass (static).
3. CONTOUR has been added but is of limited use becasue of lack of
labeling. Will add color bar soon to make Contour more useful (already
have a request for that).
4. Description updated with new keywords listed.
And yes, PSYM with or without lines works, in plot or overplot mode. And
DISPLAY does scale a plot if newly appended data extend past the
existing axes ranges (unless you set KEEP_SCALE keyword :-) And it is a
single file, not a folder full of them :-) Uh, did I mention linking of
several DISPLAY plots in different windows using a ROI feature? It is
shown at
http://www.ainaco.com/idl/idl_library/display.html
Good luck,
Pavel
P.S. Geez, it is getting almost too good to give away for free :-)
