Origin Version: 7.5G SR6
Operating System: XP

I would like to get a number of x/y data pairs by selecting them in a graph by help of a script.
The problem is that the numbers I recieve have not much in common with the points I selected.
When using the datareader I finally found out that the displayed graph and the trace on which the datareader moves are different!!

How could this be?

One part of the solution I found by myself:
in my script:

getnumber (Sourcedata) %%q (sourcecolumn) %%l (number of peaks) peaks;
win -n plot temp;
layer -i %q_%l;
layer -a;
getpts peaks;

the layer -a command has not finished when Origin executes the getpts command. So getpts expects dueto some reason that the graph is still at the "not rescaled" position. By adding "sec -p 1" after "layer -a" this problem is solved.

BUT: As soon as I try do expand or resize the graph window I have the same problem!

I can see why a pause is necessary between 'layer -a' and the getpts command but I don't understand the rest. Are you saying that getpts fails after you manually resize the graph? I can't reproduce that.

My observation is that getpts fails when I enlarge/resize the graph before placing the datareader for the first time.
Once I choose one datapoint in the graph I can resize the graph without problems and all the datapoints are consistent with the values I expect.
I guess I just have to start with a graph window of sufficient size so that enlarging the graph before taking the first point is not necessary.
