Data

The dialog Data is used to create graphs from data files.

This dialog looks very similar to the function dialog. There are some differences though. You have to select a data file to open in the first lineedit. You can use the "New" button to open a file dialog for this. In the "Read from column" section you can enter from which column you want to read the corresponding values. If unsure use the check button to have a look at the data file.

The "Read As" section selects the kind of data in the data file. The "Graph Type" selects the type of graph to create. From x-y data you can make only 2 dimensional plots. From x-y-z data you can create error and suface plots (2D data dialog) or density, contour or 3d plots (3D data dialog). From matrix data you can create density or contour plots (2D data dialog) or 3d plots (3D data dialog).
