I have Origin 7 and would like to connect points in a graph by identifying those points in the worksheet. Thus I can use a column in the worksheet to give points a particular symbol shape or size. Is it possible to have a column in the worksheet which identifies points that are to be connected by a straight line?
Thank You
Peter

Hi Peter,
I am not aware of a built-in option for connecting points by an indicator of a separate columns.
However I have 2 ideas you could try, if you are willing to deal with programming/scripting:
1. Write a script that uses the DRAW command to draw lines into your plot. The terminating points of that lines could be defined by an indicator in a column.
2. Group the points to be connected into blocks of adjacent rows and leave an empty row between the blocks. If your data is distributed randomly use a script to rearrange and introduce gaps. The script could evaluate your indicator column to perform that task.
Best regards,
Edgar

Edgar,
Thank you very much. I have done a little scripting in ORIGIN but not for a few years. Your idea for identifying lines sounds very good. I will try it. Thank you again.
Peter

Edgar,
I have used your suggestion and written a program that produces a line that connects two adjoining rows in a worksheet:
//Worksheet with 3 columns ( 1, 2, XX)
//Draw black line between point at row ii
// and point at row ii+1 if
// column XX[ii] = 4
// To run script outline and ENTER
loop(ii, 1,5){
if(data1_XX[ii]==4){
myVar1=%(data1,1,ii);
myVar2=%(data1,2,ii);
myVar3=%(data1,1,ii+1);
myVar4=%(data1,2,ii+1);
draw -w 4 -l {myVar1,myVar2,myVar3,myVar4}
}}
Thank you very much for your suggestion.
Peter
