In MatterCliff Version 1.0, the only possible Variogram type is a 'Number of discontinuities by distance' variogram.
To calculate and display a variogram follow this scheme:
Figure 3 : Variogram calculated for 500 data from a random exponential distribution (total distance of 2573.32, range = 10, 20 lags)
During the calculation, MatterCliff first calculate the number of discontinuities in the given range. Then, the lags used for the variogram calculation are 1 range, 2 ranges, 3 ranges, … In general, a number of lags corresponding to half of the total length of the scanline is sufficient.
The resulting variogram is displayed on a with (see Figure 3 above):

Figure 4 : Variogram calculated for 55 data from the clustered distribution shown below (total distance of 33.35, range = 1, 20 lags). The variogram curve reflects the periodic characteristic in the spatial distribution
For the interpretation of the variograms some trends may be used:

incrising distance distribution shown
below (total distance of 3.01, range = 0.2, 14 lags). The incrising variogram
curve reflects
a continuous incrise or decrise of the distance between successive discontinuities
