Hi everybody,
I am new to LabTalk. I am trying to write a script that would plot XY-graphs adding one more point on every next plot and save them as images. I am going to use these images for animation of the plot as Y changes as function of X. I found few topics about it. As I understand the idea: I have to create a new whorksheet and copy my XY data there in a loop with addition of the next point. I adapted the script posted by bg-phys on 07/19/2006 at 11:36:11 AM (see below). Unfortunately it doesn't work. I appreciate any suggestions or comments. Thank you in advence!
Elena.
----------
win -a Data1; // Set Data1 as the active window.
/* Loop over all rows. */
loop(ii, 1, 1067) // just like for(ii=1; ii<nR; ii=ii+1)
{
%A=MyWks$(ii); // Sets string variable "%A" to "MyWks"
// with the value of ii appended to it. (i.e. MyWks1)
win -t wks origin %A; // Open a new worksheet called %A
win -a Data1; // Set Data1 as the active window.
kk=1;
%A_A[$(kk)]=col($(1))[$(ii)];
%A_B[$(kk)]=col($(2))[$(ii)];
kk++; // same as "kk=kk+1;" which is the same as "kk+=1;"
}
%B=MyPlot$(ii); // Specify output graph name and set it to variable "%B"
win -t plot scatter %B; // Open a new scatter plot window called %B
layer -i %A_B; // Plot dataset %A_B
layer.x.from=0; // Set X-axis to start at 0
layer.x.to=100; // Set X-axis to end at 100
layer.y.from=0.01; // Set Y-axis to start at 0.01
layer.y.to=0.04; // Set Y-axis to end at 0.04
sec -p 1; // Pause, this is necessary to wait for the graph is ready
image.filename$=C:\Work\animation\%B.gif;
image.export.pagepixel(gif,640,480,24,0); // Specify the output graph pixel resolution
win -cd %B; // Close the worksheet and delete all of its data.
win -cd %A; // Close the worksheet and delete all of its data. |

Hi,
I apologize for the spam. I solved my problems with the script. In case someone needs a script to plot an accumulative graph point by point, here it is:
win -a Data1;
nR=wks.nRows;
nC=wks.nCols;
%A=MyWks$(ii);
win -t wks origin %A;
kk=1;
loop(ii, 1, nR)
{
win -a Data1;
for(jj=1; jj<nC; jj=jj+2)
{
%A_A[$(kk)]=col($(jj))[$(ii)];
%A_B[$(kk)]=col($(jj+1))[$(ii)];
kk++;
}
%B=image0000$(ii); // Specify output graph name
win -t plot "C:\Program Files\OriginLab\LINE.otp" %B;
layer -i %A_b;
layer.x.from=-100;
layer.x.to=1300;
layer.y.from=0.017;
layer.y.to=0.038; // Set the layer scale
sec -p 1;
image.filename$=C:\Work\animation\%B.png;
image.ShowOptions=0;
image.export.pagepixel(png,1024,768,24,0);
win -cd %B;
}
win -cd %A;

Hi,
I found a typo in my previous script. Now it works:
win -a Data1;
nR=wks.nRows;
nC=wks.nCols;
loop(ii, 1, nR)
{
%A=MyWks$(ii);
win -t wks origin %A;
win -a Data1;
kk=1;
for(jj=1; jj<nC; jj=jj+2)
{
%A_A[$(kk)]=col($(jj))[$(ii)];
%A_B[$(kk)]=col($(jj+1))[$(ii)];
kk++;
}
%B=MyPlot$(ii); // Specify output graph name
win -t plot scatter %B;
layer -i %A_b;
layer.x.from=0;
layer.x.to=1;
layer.y.from=0;
layer.y.to=1;
sec -p 1;
image.filename$=d:\test\%B.gif;
image.export.pagepixel(gif,640,480,24,0);
win -cd %B;
win -cd %A;
}
I have another question though. Could anybody tell me how I can apply a desired template for graphs in my script? Thank you.
Elena. |
