Igor Pro 7 Macro: Batch Save All Graphs as PNGs

Mon, 08/04/2025 - 10:49 am

I’ve seen many different scripts shared for saving graphs from the Procedure window in Igor Pro, and I wanted to create a more streamlined and reusable version. So I refined them and packaged everything into a simple macro you can easily add to your Igor Pro setup.

This macro is mostly based on the procedure introduced by Tony Withers, with a few improvements and refinements for clarity and ease of use.

I developed and tested this on Igor Pro 7 for Windows, but it might work on other versions as well; feel free to try it and let me know!

What It Does:

This macro allows you to save all open graphs at once as .png files in a subfolder called Graphs located in the same directory as your .pxp file.

There are two functions you can use:

SaveAllGraphsN() — Saves graphs using their window names. (Will override files if names repeat.)
SaveAllGraphsT() — Saves graphs using their titles. (Will prompt for a new name if duplicate titles are found.)

Usage Instructions:

Open the Procedure Window in Igor Pro.
Paste the following code.
Compile it.
Or: To have the function in all of your projects, save the macro (.ipf) file and place it in:
This PC\Documents\WaveMetrics\Igor Pro 7 User Files\Igor Procedures

To quickly access that folder, go to Help > Show Igor Pro User Files inside Igor.

Once it’s installed, simply run one of the commands mentioned, in the Igor command line.

code:

// Procedure 1:
// Save graphs using their window "Name"
// WARNING: This will override files with the same name
 
function SaveAllGraphsN()
    int NGraphs, i
    string graphList, currWindow
 
    graphList = WinList("*", ";", "WIN:1")
    NGraphs = ItemsInList(graphList)
    PathInfo home
    NewPath/C/O/Q graphs, S_path + "graphs:"
 
    for (i = 0; i < NGraphs; i += 1)
        currWindow = StringFromList(i, graphList)
        GetWindow $currWindow, wtitle
        SavePICT/O/E=-5/P=graphs/WIN=$currWindow as currWindow + ".png"
    endfor
end
 
// Procedure 2:
// Save graphs using their "Title"
// WARNING: Make sure your titles don’t contain "/" or parentheses
// If you're sure there are no duplicate titles, you can add \O to the SavePICT line to override
 
function SaveAllGraphsT()
    int NGraphs, i
    string graphList, currWindow
 
    graphList = WinList("*", ";", "WIN:1")
    NGraphs = ItemsInList(graphList)
    PathInfo home
    NewPath/C/O/Q graphs, S_path + "graphs:"
 
    for (i = 0; i < NGraphs; i += 1)
        currWindow = StringFromList(i, graphList)
        GetWindow $currWindow, wtitle
        SavePICT/E=-5/P=graphs/WIN=$currWindow as CleanUpName(s_value, 1) + ".png"
    endfor
end

To have the function in all of your projects, save the macro (.ipf) file and place it in: This PC\Documents\WaveMetrics\Igor Pro (1.46 KB)

After consideration and with due respect to the IP7 thrust for the code snippet posted here, I've moved my code snippet to a different thread. I want to avoid any confusion should certain portions of what I posted be inclined to fail under IP7.

I appreciate the inspiration!
