| pmat | set a data matrix for subgraphs |
| <graphic> | name of the graphic structure |
| -n <name> | name of the point matrix |
| -id <subgraph> | the idendifier of a subgraph |
| -d <data> | data to be displayed |
| [-sca <scaling>] | scaling function, default=DATA |
| [-min <min>] | minimum value |
| [-max <max>] | maximum value |
| [-co <color>] | color for the histogram bars |

This command displays the values of the given data in a subgraph as a matrix. One row corresponds to one data record, and one column to one field, respectively. The values are displayed as gray levels or pseudo colors, depending on the flag -rgb. The scaling parameters define how the values are mapped to the colors. The values can be either integer or floating points.
Example (ex7.35): The following commands generate data using a sine function, create sequences of the values and show the sequences in the data matrix.
NDA> setdata -f d.i -vals 0=0.0; -t float -len 30
NDA> serie -d d -fout d.x
NDA> expr -fout d.x -expr 2 * 3.14 * FLOAT('d.x') / LEN("d.x");
NDA> expr -fout d.y -expr SIN('d.x');
NDA> select data -f d.y
NDA> concseq -d data -dout data1 -len 5
NDA> mkgrp win1
NDA> addsg win1
NDA> pmat win1 -n rm -id 0 -d data1
