The automatic and manual radio buttons allow the user to select the update mode for the profile panel.In both the X and Y dimensions, the user will see three color coded profile lines on the plot representing the red, green, and blue bands if the displayed image is color. If the displayed image is black and white, there will be only one profile line.

- Y:
- The x-axis of the profile plot represents 1 to the number of displayed lines (a single column of image data). The y-axis represents the corresponding gray level value of each pixel (0 to 255).
- Z:
- The x-axis of the profile plot represents 1 to the number of image bands loaded. The y-axis again represents the corresponding gray level value of each pixel.
