| Description: | Collects certain data from a plot. The dataset must be shown in the plot using show or adddata. |
| Usage: | data=getdata(di, row_num, col_num, data_num) | |
| Input: | ||
| di | string, name of the display | |
| row_num | integer, represents the number of a row of the display di | |
| col_num | integer, represents the number of a column of the display di | |
| data_num | integer, represents the number of a data set shown in the plot | |
| Output: | ||
| data | a complex object that includes the following components: | |
| data.data | a matrix of the coordinates of the plotted points | |
| data.pcolor | n x 3 matrix representing the color of the plotted points | |
| data.pstyle | n x 1 matrix representing the style of the plotted points | |
| data.psize | n x 1 matrix representing the size of the plotted points | |
