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
