And a osg vector expand to set pointers? Is it a bad idea?
The problem there is that there's no way to pass these separate arrays to OpenGL in an efficient manner.
Having two separate arrays for X/Y is pretty much worst case, even having them interleaved in one array would be better.
Hm, you could try to bind each array as vertex attribute and fetch the vertex position from these (in a vertex shader) ... but since there's no way for OSG or OpenGL to know which pieces of your data have changed it would need to upload the entire dataset every time anyhow.
