Dear group,

I'm an ImageJ-beginner and want to write a macro that reads values from the Results window/table.
First I run the "Color Histogram" plugin. It creates a nice histogramm window and writes data to the Results window.
Then I try to read the mean red value but I always get the error message: "Results table empty in line 2".

This is the code I'm using:
  run("Color Histogram");
 mred = getResult("red",0);

The Results window shows this:
 -     red         green    blue
mean 235.51 240.76 219.23
st.dev 5.97 4.54 4.73

Any suggestions or hints?

Thanks in advance

Maart
