Hello All,

I am sure this is a simple one. But i am struggling to increase the thickness of the line after doing a linear fit to my scatter graph.



As you can see the red line which is the linear fit is too thin which I would like to increase automatically through labtalk code. Also is it possible to move the table to a different Position using coordinates in labtalk?

Thanks a lot in advance.
-Akki

such coding! much wow!

Hi Akki,

I did so just for the precaution just in case when the current window doesn't have any table
object, and unless initializing the value, the old content from the last time might still remain.
Maybe I should declare the variable to make it "local (or session)" - string tname$=""; rather
than having such undeclared "project" scope.

I'm sorry for that I'm a lazy programmer (though actually I'm not a "programmer").

I hope the following snippet helps you to code:
////////////////////////////////////////////
//Run the following lines after fitting on the graph
range rr = [%H]1!2;  //2nd plot in current graph window
set rr -w 2000;  //set line thickness
tname$=""; //table name
doc -e G {
  ch5$=Left(%B,5)$;
  if(ch5$=="Table") { //if table is found
    tname$=%B;
    Break;
  }
}
%(tname$).width=2500;  //table width
%(tname$).height=1500; //table height
%(tname$).top=580;    //table top position in pixel
%(tname$).left=1150;  //table left position in pixel
////////////////////////////////////////////

Your code works perfectly! thanks a lot.. thats exactly what i wanted. A question just for my knowledge because I experience a lot of Problems handling strings. Is it necessary to initize a string variable to a empty string always? like in your code:

tname$=""; //table Name

or is there an Advantage to this?
