This command calculates the integral of data set <ik>. If the additional parameters are omitted, the complete actual plotting window is integrated. Alternatively, the integration limits <xmin>,<xmax> (2d) or <xmin>,<xmax>, <ymin>,<ymax> (3d) can be given after the data set number <ik>.
The results of this command are stored in the res[i] variables in the following order:
res[0] : Number of parameters given res[1] : Integral res[2] : Sigma of the integral res[3] : # of points integrated res[4] : Integration limit xmin res[5] : Integration limit xmax res[6] : Integration limit ymin (only for 3d data) res[7] : Integration limit ymax (only for 3d data)
