Save the entire chunk of code as 'grapharray.pro', compile it and call
it as an IDL function:
Output = Grapharray(Xvalues, Yvalues)
When the program returns (after you right-click in the window), your
array will be stored in the Output variable.
Also, this line:
Diffs = XDiffs + YDiffs
Should probably read:
Diffs = SQRT(XDiffs^2 + YDiffs^2)
Good luck,
Chris

So if a catalyst makes things happen faster, does that mean an analyst
is *meant* to make things happen slower??
That explains a few things ;-)

It's "catalyst", rather than "analyst", but that's
the basic idea. :-)

I just fixed it by downloading the latest version of David's entire
library from
http://www.dfanning.com/programs/coyoteprograms.zip
Into a folder on my !Path
I guess I also restored the analyst.sav file, but I'm not sure if
that's necessary if you have everything set up right:
CD, [Coyote Library Folder]
RESTORE, 'analyst.sav'
Regards,
Chris
PS Here's a simple version of what I use to do what I think you want.
It's not efficient, with all those Wait calls and unnecessary
concatenations, but it works:
Function GraphArray, X, Y
Window, /Free, Title = $
'Left click to store values, right click when done.'
WIndex = !Window
Loop:
Plot, X, Y
Cursor, xp, yp, /Data, /Down
; Right button or kill/change window to quit:
If !Mouse.Button Eq 4 Or !Window NE WIndex Then Begin
Print, 'Returning.'
If !Window Eq WIndex Then WDelete
If N_elements(Array) Eq 0 Then Return, 0
Return, Transpose(Array)
Endif
; Draw X where user clicked
OPlot, [0,xp], [0,yp], PSym=2
; Work out nearest point on graph line
XDiffs = Abs(X - xp)
YDiffs = Abs(Y - yp)
Diffs = XDiffs + YDiffs
Void = Min(Diffs, Index)
NX = X[Index]
NY = Y[Index]
NearPt = [ NX, NY ]
; Draw a diamond on actual datapoint stored to array.
OPlot, [0,NX], [0,NY], PSym=4
Wait, 1.5
; Store values
If N_Elements(Array) Eq 0 Then $
Array = Transpose(NearPt) Else $
Array = [Array, Transpose(NearPt)]
Goto, Loop
End

Are you sure you are using the latest catalyst.sav version?
I did, long ago, have a version out there there was missing
this Catalyst Library object. But the latest appears to have
it.
I should probably update this, as I have made lots of changes
lately, but I'm enjoying the beach this week. :-)
Cheers,
David

I was about to point Dave to David Fanning's ANNOTATEWINDOW, but I
can't get it to work, even after updating my Coyote library.
I get the following error:
% Attempt to call undefined procedure/function: 'COLORTOOL__DEFINE'.
% Error occurred at: ANNOTATEWINDOW 186
Searching David's site and the IDL helpfiles, I can't seem to find
mention of the ColorTool object class anywhere. What am I missing?
