                          GogPlotBoundInfo *bounds);

Queries plot for its axis preferences for axis and stores the results in bounds . All elements of bounds are initialized to sane values before the query _EXCEPT_ ::fmt. The caller is responsible for initializing it. This is done so that once on plot has selected a format the others need not do the lookup too if so desired.

Caller is responsible for unrefing ::fmt.
