Hi, I am having a problem manipulating datasets. Whilst a plot window is active I am having problems manipulating dataset with '-=' command among others. It does not matter if the dataset is temporary or exists in a worksheet. If I make the worksheet active everything runs as it should. See example below.

If I run the following script it produces the following output.(I've include the type commands as pointers to what I am acting on/with). Here %w contains the name of the worksheet (in this case 'E01A2') & 'Bubble' is the name of the plot window.

del tempdataset;
mark1b=;
type "%%w = %w";
type "%%h = %h";
type "%%c = %c";
yoffsetval=;
tempdataset=%c;
%c[mark1b]=;
type "%%h = %h";
tempdataset[mark1b]=;
tempdataset -= yoffsetval;
tempdataset[mark1b]=;

type "----------------------------------";

type "%%w = %w";
type "%%h = %h";
type "%%c = %c";
yoffsetval=;
tempdataset=%c;
%c[mark1b]=;
win -a %w;
type "%%h = %h";
tempdataset[mark1b]=;
tempdataset -= yoffsetval;
tempdataset[mark1b]=;

MARK1B=303226
%w = E01A2
%h = Bubble
%c = E01A2_Accel
YOFFSETVAL=-755.1433253322
E01A2_Accel[MARK1B]=-703.13449725961
%h = Bubble
TEMPDATASET[MARK1B]=-703.13449725961
TEMPDATASET[MARK1B]=-703.13449725961
----------------------------------
%w = E01A2
%h = Bubble
%c = E01A2_Accel
YOFFSETVAL=-755.1433253322
E01A2_Accel[MARK1B]=-703.13449725961
%h = E01A2
TEMPDATASET[MARK1B]=-703.13449725961
TEMPDATASET[MARK1B]=52.008828072584

In the first instance I have a plot window active with the plot described by %c in this case the temporary dataset is not acted upon by the '-=' function.
However if I switch to the worksheet prior to the "-=" function it acts as expected.

Why?

If I remove the temporary dataset from the code and replace it with a real worksheet data column I still get the same thing.

MARK1B=303226
%w = E01A2
%h = Bubble
%c = E01A2_Accel
YOFFSETVAL=-755.1433253322
E01A2_Accel[MARK1B]=-703.13449725961
%h = Bubble
E01A2_BUBBLE@2[MARK1B]=-703.13449725961
E01A2_BUBBLE@2[MARK1B]=-703.13449725961
----------------------------------
%w = E01A2
%h = Bubble
%c = E01A2_Accel
YOFFSETVAL=-755.1433253322
E01A2_Accel[MARK1B]=-703.13449725961
%h = E01A2
E01A2_BUBBLE@2[MARK1B]=-703.13449725961
E01A2_BUBBLE@2[MARK1B]=52.008828072584

why do I need to have the worksheet active in order to manipulate the dataset?
Is it because I have too large a dataset > 500 000 points?

thanks Andrew
