Image Histogram

The Image Histogram dialog box is displayed when you select ROI -> View -> ROI Histogram from the Measure menu. Or <Ctrl>+h. A region of interest (ROI) must be set in the active dataset for this option to be enabled.

Hold curve:

Freeze the current ROI. This will leave the current histogram for the ROI unaltered, and subsequent changes in the ROI will generate a new histogram next to the old one.

Clear curve:

Clear the ROI histogram last froze by Hold curve.

Options:

Open the histogram options dialog.

Copy figure:

Copy the entire ROI Histogram figure to the Windows Clipboard.

Copy data:

Copy the histogram data to the Windows Clipboard. This will copy the data as a ; delimited text file with two columns and number of rows equal to the number of bins set in the Number of bins option. The first column contains the mean pixel intensity for the bin and the second column contains the number of pixels in the bin.

Tips:

• By using the Copy figure and Copy data tools you can copy the histogram and its data and paste it directly into other Windows applications such as MS Word, Powerpoint, Excel etc.
