| env | Chart environment structure | |
| xvalues | Array of x-axis data values | |
| yvalues | Array of y-axis data values | |
| n | Number of data values to chart | |
| nseries | Number of series to chart | |
| rowdim | Row dimension of data array | |
| serieslabels | Array of labels for series |
The _pg_chartscatter function displays a scatter diagram for a single series of data.
The _pg_chartscatterms function displays a scatter diagram for more than one series of data.
The arguments xvalues and yvalues are two-dimensional arrays containing data for the x axis and y axis, respectively. Columns for each array hold data for individual series; thus the first columns of xvalues and yvalues contain plot data for the first series, the second columns contain plot data for the second series, and so forth.
The n, rowdim, nseries, and serieslabels arguments fulfill the same purposes as those used in the _pg_chartms function. See _pg_chartms for an explanation of these arguments.
For a discussion of the chart environment and related topics, see “Presentation-Graphics Functions”.
The _pg_chartscatter and _pg_chartscatterms functions return 0 if there were no errors. A nonzero value indicates a failure.
