[Data]-[Read Multicolumn]

This function is used to read plural data sets like {x vs. y1}, {x, vs. y2}, {x, vs. y3} from a data file at a time. For this the text data file should have the following formats or similar.

T/K, AuFe-Chromel, Cu-Constantan, Chromel-Constantan
273, 22.267, 38.690, 58.644
274, 22.274, 38.769, 58.730
275, 22.280, 38.848, 58.816
276, 22.284, 38.927, 58.903

Namely, "T/K" is x-data and the other columns are y-data, respecively. One doesn't have to have x-axis data at the first column.
