Hi all,
In gmsh Statistics window, I can see the statistics of a mesh. 
Using the input file in the tutorials, say, t1.geo, the output file t1.msh  say there is totally 497 nodes.
But in the  Statistics window, it is shown that there are 84 nodes on line,  409 nodes on the surface.
Why these statistics dont't match each other?

Thank you!
