Any hints about what would the best way to do that?

Is there any setting that controls the extent of a plot?

Left hand plot has defined extent of the plot, while the plot on the right hand side has not. When panning the graphics on the right side the plot is clipped.

Any idea how to make Maple to use the whole extent of the plot component as a boundary?
