The histogram tool is designed to allow the program developer to plot and display data distributions anywhere within the software, without the need to have to write additional display software. Histograms are generated and filled using the "hbook" and "hfill" library functions (see Programmers Guilde).
The current histogram for display is manipulated by the 
and
buttons. Each will find the next available histogram in the specified
direction.
factor Generate a Tv for dsplay.
plot hist Display the current histogram if 1D. If a 2D scatter plot, form an image for display in the Imcalc Tool.

integrate hist
