How to resolve "no plot window"

[fieryice12]

I am writing a macro to batch process multiple files in a folder. When I run
this code, I'm getting the error message "No plot window in line 6". What is
causing this and how can it be fixed? Thanks in advance.

function action(output, filename)
{
        open(input + filename);
        makeRectangle(75, 47, 40, 42);
        run("Plot Z-axis Profile", "profile=time");
        Plot.showValues();
        saveAs("Results", output + filename);
        close();
}

input = "C:/Users/Admin/Desktop/Input/";
output = "C:/Users/Admin/Desktop/Output/";

setBatchMode(true);
list = getFileList(input);
for (i = 0; i < list.length; i++)
{
        action(output, list[i]);
}
setBatchMode(false);

Hi,

It seems like an issue with batch mode. It works for me when I comment out
the setBatchMode(true).

Also, as an aside, you may want to change:

  saveAs("Results", output + filename);

To:

  saveAs("Results", output + filename + ".txt");

So that your results aren't saved into files that look like (but are not)
images.

Regards,
Curtis

That solution fixed the problem. The suggestion to append ".txt" is also
helpful to prevent the output from being generated as .tif files.

This is a batch mode bug that is fixed in the latest daily build (1.52p45). You also need to change the statement that saves the table to

    saveAs("Results", output + filename + ".csv”);

or you will not be able to open the table in ImageJ.
