In the Graph Controls window, you can adjust the x and y axis of a profile. You can also change the background color of the graph and select whether to lock the aspect ratio between the x and y axis.
The range varies according to the ground distance covered by the image and the length of the vector. The range default value depends on the image bit depth (for example, 8-bit, 16-bit, and so on).
Setting up a new range
Under X View Range and X View Range, respectively, the range of the graph is determined by the values of the Min. and Max. boxes. To set up a new range, type or select new values in the boxes, as necessary.
If you want to retain the original relationship of the x and y axis, under Options, select the Fix aspect ratio check box. To adjust the x and y axis independently, make sure the check box is clear.
Legend and color controls
By default, a legend of the applicable color channels is displayed in the Profile Graph window. If necessary, you can turn off the legend to increase the available display area of the graph. To remove the legend from the display, under Options, clear the Show legend check box.
To set the background color of the graph display, click the Background list, and then from the palette, click the color you want. To select from additional colors, click More.
