To build a contour maps, the program interpolates each data point value
onto the grid nodes. An orthogonal 100x100 grid is automatically overlaid to encompass all
data points and borders.
Use the Objects | Grid dialog to make the grid finer,
typically to obtain smoother contours, or to define the grid with square cells. The length
of a square cell side should be given units of X and Y. Click the
Advanced button to create a irregular grid or save/load it.
If the Auto load box is checked, the grid
is loaded from the directory when you open the data file in this directory
(if the EqNet.net file was created in previous session).
The Show/Hide grid button in the
toolbar panel shows or hides the grid. The grid parameters are automatically stored in the
directory of input data (EqNet.net file).
Use the commands from context menu for the Grid tree item:
