How do I change the presentation of histograms (color of lines, offset)?
To change color, click on the colored box in the legend that is next to the name of the sample you want to change and a palette will pop up. Pick the color you like from the palette. To change the line, click on the line next to the color box in the legend and choose from the popup menu. If you wish to change the color and line of a single histogram, first display the legend. Double-click on the histogram and under the Annotate tab, click the Show Legend box. For more information, click here. Note that version 4 changes all this–you can directly specify all colors for any graph.
