The decriptor should be of the type integer, real or double precision; default is HISTOGRAM \ap\pa start,end = first and last data point to be plotted; end can be smaller than start; defaults are the first and the last valid data points in the descriptor. \ap\pa x_sc,y_sc,x_off,y_off = scale or size in the x- and y-direction, offset in the x- and y-direction. For the scaling x_sc and y-sc, positive numbers are interpreted as scale parameters (world units/mm), negative numbers as size parameters (axis will be made sc_* mm. long). A combination of a positive and negative number is allowed. By default the plot fills the device area. \\ x_off and y_off determine the distance of the lower left corner of the plot to the lower left corner of the graphic device, measured in mm. By default, the plot is put at the top left of the graphic device, allowing space for the various labels. \ap\no Note: The command is useful to plot data stored in a descriptor. The maximum number of data points in the descriptor that can be plotted is 10000. With more data points one should use additional overplot commands. \on\see See also: WRITE/DESCIPTOR, READ/DESCRIPTOR, COPY/DD, COPY/DK, COPY/KD \ees\exs Examples: \ex PLOT/DESCRIPTOR myframe histogram 100,125 This will plot the descriptor histogram associated with the image myframe.bdf. Only the elements 100 to 125 will be plotted. The descriptor must exist. In this case, it should have been created previously by the command STATISTICS/IMAGE myframe. \xe \sxe
