This article contains a sample Grapher script which shows how to create a graph with multiple line/scatter plots from adjacent Y columns. The Y column automatically increments to the next column in order to create the next plot. So, for example, if you had a data file with 4 columns, the first line/scatter plot would use column 1 for x and column 2 for y, the second plot would use column 1 for x and column 3 for y, and the third plot would use column 1 for x and column 4 for y.
To run this script:
- Copy the script below, download the attached CreatePlotwithDifferentY.bas file.
- In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Grapher 12\Scripter.
- Double click on Scripter.exe to launch Scripter.
- Press Ctrl+A to select all of the existing lines then press Delete.
- If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
- Click Script | Run to run the script.
