Description: Histogram Plot Type Command: Sets the plot type to HISTOGRAM.
When the plot type is HISTOGRAM, the DRAW command creates a histogram using data from one column of the current statistics matrix (reserved variable ΣDAT). The column is specified by the first parameter in the reserved variable ΣPAR (using the XCOL command). The plotting parameters are specified in the reserved variable PPAR, which has the form:
{(xmin, ymin) (xmax, ymax) indep res axes ptype depend } For plot type HISTOGRAM, the elements of PPAR are used as follows:
•(xmin, ymin) is a complex number specifying the lower left corner of PICT (the lower left corner of the display range). The default value is
•(xmax, ymax) is a complex number specifying the upper right corner of PICT (the upper right corner of the display range). The default value is (6.5,3.2) for the HP 48gII and (6.5,4.0) for the HP 50g and 49g+.
•indep is either a name specifying a label for the horizontal axis, or a list containing such a name and two numbers that specify the minimum and maximum values of the data to be plotted. The default value of indep is X.
•res is a real number specifying the bin size, in
•axes is a list containing one or more of the following, in the order listed: a complex number specifying the
•ptype is a command name specifying the plot type. Executing the command HISTOGRAM places the command name HISTOGRAM in PPAR.
