IDW not working properly?

[AdrianCovasnianu]

Hi!

I'm trying to use IDW interpolation method, but the result looks like it didn't take into account the all points.

The extent of the result (raster) isn't containing all the points and consequently the result is partially wrong.

I'm attaching the result in order to see more clearly what I'm speaking about.

Thanks in advance!

Your surface is covering all the points.  The default extent of a geostatistical layer is the rectangular extent of the input points. 

The layer isn't covering the entire picture of some of the points because you've used large symbols, but the layer is still covering the location of the points (the centers of the circles).

Thanks.
I've corrected the problem.
