Extracting Plot Values

[Norbert Vischer-2]

Hi All,

we often want to reproduce an ImageJ plot in another program like Igor.
To extract the plot values,  we click "List" in the plot window. However, in the example below I only get columns "Y1" and "Y2", while "X1" and "X2" are missing. Secondly,  "Y2" only shows rounded integers.

macro "Simple Plot" {
        xValues1 = newArray(1,   2,   3,   4);
        yValues1 = newArray(1,   4,   9,   16);
 
        xValues2 = newArray(1.1,  2.1,   3.1,  4.1, 5.1);
        yValues2 = newArray(1.11, 2.22, 3.33, 4.44, 5.55);

        Plot.create("Simple Plot", "X", "Y");
        Plot.setLimits(0, 5, 0, 20);
        Plot.add("line", xValues1, yValues1);
        Plot.setColor("red");
        Plot.add("circles", xValues2, yValues2);
   }

These bugs are fixed in the 1.45q daily build.
