34.49.63 Table

Instead of producing a graph, the table terminal prints out the points on which a graph would be based, i.e., the results of processing the plot or splot command, in a multicolumn ASCII table of X Y {Z} R values. The character R takes on one of three values: "i" if the point is in the active range, "o" if it is out-of-range, or "u" if it is undefined. The data format is determined by the format of the axis labels (see set format), and the columns are separated by single spaces.

For those times when you want the numbers, you can display them on the screen or save them to a file. This can be useful if you want to generate contours and then save them for further use, perhaps for plotting with plot; see set contour for an example. The same method can be used to save interpolated data (see set samples and set dgrid3d).
