This dialog is displayed by double-clicking a spot, or from the Edit Spots dialog.
Description
Type a description, if desired. The description is not displayed except in this dialog.
Color
Click this button to choose a color for the spot. The standard color selection dialog is displayed.
Size
Spots can be of different sizes. The size field is a percentage of the histogram area. So, a value of 10 causes the spot to be 10% of the width and height of the histogram.
Relative positions
The spot keeps track of its position in each parameter of the listmode file. The positions are in percentage units, so a value of 50.0 positions the spot at the halfway point in the parameter. These values can be edited directly, or you can use the mouse to move the spot graphically.
