Origin Version (Select Help-->About Origin): 7GSR2
Operating System: XP
Hi,
I am starting with programming LabTalk in Origin. So I am a true Rookie in this filed. After checking out this forum and looking into the LabTalk help I am wondering about a fact I am not able to understand.
Hereīs my problem:
I have a worksheet with 24 columns of wich the first one (A) is a date and the following ones (B to X) are data to be plotted. As each column contains about 60 000 values I decided to plot the data in several graphs. As the column A contains the date in 18 different time regions I generated 18 Graphs. After I had generated these 18 Graphs I saved this File. These 18 graphs contain only one column, e. g. column B. How can I replace this column B with column C and so one and place the graphs in a new folder within the origin project automatically?
The way I tried to solve the problem (of course I have no idea of how to copy the generated graphs in a new folder!) was
//assume that column b actually is plotted and column c should
//be plotted now in Graphs 1 to 18
Graph1!page.active = 1
layer -c;
layer -e %Z;
layer -i200 data1_c
//Go on to the next Graph. I donīt know how to do this in a
//loop for all Graphs
I think the first command should acitvate Layer 1 from Graph 1. But this doesnīt work! When Graph 4 is active, all the following commands work in Graph 4! Obviously there is something wrong! But I donīt know what!
Can anyone help me please? Thanks in advance

Hi again,
it seems like this works:
for
(jj=2;jj<=20;jj++)
{
for
(ii = 1;ii<=19;ii ++)
{
%A = Data1!wks.col$(jj).name$;
%A = Spalte_%A;
Data1!wks.col$(jj).label$ = %A;
pe_mkdir(%A);
pe_move(%A,"/Filename");
window -a Graph$(ii);
page.active = 1;
layer -c;
layer -e %Z;
layer -i200 %(Data1,jj);
layer.x.rescale = 1;
layer.y.rescaleMargin = 2;
layer -a;
window -d;
window -r Graph20 %A_$(ii);
%B = /Filename/%A;
pe_move(%A_$(ii),%B);
};
};
So long

By the way:
Is there any possibility to "increase" a character? I would like to automatically rename the columns from "column_B" to "column_X".
It should work like this:
for
(ii=2;ii<=24;ii++)
{
%A= column_/**Now here should be a term that makes it possible to convert the number ii (for instance "2") to the ii th (for instance "second") character of the alphabet (namely "B")/*
data1!wks.col$(ii).label$ = %A
}
Any ideas?
Thanks in advance

Hi Steffen,
Easiest to start with your last question.
>> It's not necessary to write the loop script in one line. Ending a line with semicolon and pressing Enter (or Ctrl+Enter) should not generate a command error. Line is executed when you press Enter without the semicolon.
>> As far as plotting columns D and later, consider replacing the wksName_colName dataset notation with %(wksName,colNumber). For example,...
for(jj=3;jj<10;jj++) {
layer -i200 %(Data1,jj);
};
>> You need help from Origin C to work with folders. The following Origin 7.5 functions (pe_mkdir and pe_move) work in 7.0 SR4. Add them to your workspace as described here...
http://www.nmrtools.com/labtalk/tryOC.html

void pe_mkdir(string subfolderName)
{

Folder subfld = fld.AddSubfolder(subfolderName);
if( !subfld.IsValid() )

}

void pe_move(string strItemName, string strPathName)
{
Folder fld = Project.ActiveFolder();
if( !fld.Move(strItemName, strPathName) )

}

Hi again,
I went through the problem again and found out the following command works:
for (ii = 1; ii <= 18; ii ++)
{
window -a Graph$(ii);
page.active = 1;
layer -c;
layer -e %Z;
layer -i200 DATA1_d;
}
With this command I only have to replace DATA1_d to e, f, and so on and then save the file. I thought about to autorescale the graph with the following command.
layer.x.rescale = 1;layer.y.rescaleMargin = 2;layer -a;
Without the for-loop this works fine. Within the loop it doesnīt work. Also the problem with shifting the graphs into another folder has not yet been solved.
Another question: When writing the for-loop in the script window it only works when writing it in a line. Trying to structurate the loop gives back the message #command error. Isnßt it possible to structurate the commands in order to have a better understanding of what is going on in the command?
So long
