From the main menu, select: Plot → Scatterplot

All the selected data are sent to this window (triangles of meshes are not yet included).

Select the X and Y axes from the list-boxes on top-left (double click the field) and a scatterplot will be drawn.

There are three options for plotting data.

Data: plots a scatterplot. The size of point can be customised in the Drawing options (Plot options tab: scatterplot circle width and stroke).

Interval: divides the X axis in a number of intervals defined by the slide-bar value. Define if Y-values are normal or circular and then click “Apply”. For each X-interval the average value, the standard deviation and, for non circular data, the skewness and the kurtosis of the Y field are computed. Select the parameter to be plotted, eventually change the Y scale, and then click “draw”.

Frequency: draws frequency contours.

To draw contours you have to specify:

The grid size (Y and X intervals).

If Y and/or Y values are circular

If data have to be normalised to the relative maximum in the corresponding X or Y interval or to the absolute maximum of the grid.

The distance parameter, i.e. the distance between a datum and the cell's centre

The smoothing (i.e.the number of nearest cells on which perform the smoothing)

The number of contours

Once the contouring has been drawn, it can be also exported as *.dat file.

The pop-up menu allows to export the graph as vector (SVG) or copy it to the clipboard
