hey there,
i got a little problem. I try to rescale the yaxis of my data, so that for the following script it will be immediately plottet as logarithimic or as the square root. Unfortunately I cannot find the proper lab talk script for it.I can do it manually, however would prefer it to include it to the following script:
dlgfile gr:=Excel mu:=1;
loop(ii,1,fname.GetNumTokens(CRLF))
{
file$ = fname.GetToken(ii,CRLF)$;
// Customize Excel import options as needed
impExcel fname:=file$
lname:=1
desig:=<Unchanged>
options.names.FNameToBk:=0;
// Einheiten in Tabelle schreiben
col(3)[U]$="A";
col(2)[U]$="V";
plotxy (2,1) plot:=200;
}

thanks a lot in advance

Hi,

To change the axis scale type, you can use


//Set Y axis as log10
layer.y.type = 2;
//Set X axis as square root
layer.x.formula$=sqrt(x);
layer.x.invformula$ = x^2;
layer.x.type = 11;


Please visit our LabTalk document for further information of Layer.Axis.type.
http://www.originlab.com/doc/LabTalk/ref/Layer-Axis-obj

Please note that layer.x.formula$ and layer.x.invformula$ only support in Origin 9.1 and later version. Please try it in version 9.1. You can try our demo here:
