Hello,
In a line plot, I need to plot a single line in different colors. For example, if X axis is from 1-1000, I want a plot such that line between 300-500 is red and the rest of it is green. Can anyone suggest a technique how to accomplish this ?
Thanks in advance. |

How about using (XYXY-)Vector Plot?
You need to create 3 columns. Second column copied from the first shifted one cell down, and you can set color# in the third column. Then, you can make a vector plot, with color indexed by the third column, and the size=0 for the arrow head.

The more general solution suggested by Hideo can be accomplished with this script:
// BEGIN SCRIPT
wks.col=3;
wks.insert(EndX EndY);
wks.col3.type=4;
wo -s 1 0 2 0;
DoMenu 57634;
wo -s;
wo -s 3 0 4 0;
DoMenu 57637;
get wcol(1) -e end;
wo -s;
wo -s 3 1 4 1;
DoMenu 36442;
wo -s;
wo -s 0 end 0 end;
DoMenu 36442;
wo -s;
wo -s 1 0 4 0;
wo -p 218 ColoredLineSegments;
// END SCRIPT
which assumes your worksheet with columns A(X), B(Y) and C(Y) is active and that you have saved a Template named ColoredLineSegments.
In your particular case, that C column should contain 2 where X is 300 to 500 and 3 elsewhere. This script does just that:
// BEGIN SCRIPT
col(C)=((col(A)<300)||(col(A)>500))?3:2;
// END SCRIPT
TO MAKE THE ColoredLineSegments TEMPLATE:
Setup a worksheet as A(X) B(Y) C(X) D(Y) E(Y)
Fill a few rows of A(X) with row numbers
Fill a few rows of C(X) with row numbers plus 1
Fill a few rows of B(Y) and D(Y) with any values
Fill a few rows of E(Y) with integers from 1 to 24
Select columns A(X) to D(Y) and plot as a Vector XYXY plot
Double-click on the plot to open Plot Details
Set the Arrowhead Length to 0
Click the Color button and choose Indexing : Col(E)
Click OK out of Plot Details and File : Save Template As and enter ColoredLineSegments as the template name.
