Point layers on top of Point layers

Hi all,

Here's the scenario.. I have two shapefile layers, "A" on top of "B".

Both are point shapefiles and the points in "B" are a subset of the points in "A". When I define the Drawing options, I make the point size of "B" greater than the pointsize of "A".

My expectation is that I'd see a small dot for Point "A", with a larger "B" dot beneath it.

When using the control, though, I don't see any "B" points until I hide layer "A". (Presumably because a point sits on top of another point?)

Is there a way to force the two points to be shown so that I see point "A" on top of point "B"?

Yes use shape collision. http://www.mapwindow.org/documentation/mapwingis4.8/class_shapefile.html#ae0c2b5b354f003d50bca9efbe82ee08e the documentation says its for labels but I think that may be a misnomer. Labels have something else http://www.mapwindow.org/documentation/mapwingis4.8/group__labels__visibility.html#ga45a0ade2551e6e91df8183b8f875dda4

I like you assumed this was on by default but its actually off by default, meaning collisions are avoided by default.

That was it! I recall seeing the property but assumed it was labels only based on the documentation.

Much appreciated, sindizzy!!
