Hello, I need to find a way to apply a offset and scaling factor to the X and Y axes on an image plot. Instead of showing the pixel number I would like to transform the axes to 'world' coordinates, in this case degrees of Rightascension and Declination in an astronomical image. The transformation is defined on both axes via an offset and a scaling factor. For example in PGPLOT this can be accomplished by specifying a transformation vector with the call to 'pgimag()'. http://www.icp.unistuttgart.de/~feri/pgplot.html#PGIMAG Despite looking at the examples in the tarball I cannot seem to find similar functionality  likely because I am new to matplotlib. Can anybody point me in the right direction? Thanks, Cormac
