# Control the size of graphics

It could be a very silly question!

Suppose we have the simple case

p1 = ListPlot[{{-0.4, -0.24}}, PlotStyle -> {GrayLevel[0.4], PointSize[0.09]}];
p2 = Graphics[{GrayLevel[0.4], Ellipsoid[{0.9, 0.6}, {3, 2}]}];
Show[{p1, p2}, PlotRange -> All, ImageSize -> 500] How can we control the size of the ellipse? I added ImageSize -> 10 but it does no have any affect...

Any ideas?

• @eldo What do you mean? – Vaggelis_Z Jul 14 '17 at 17:15
• Show[Graphics[{GrayLevel[0.4], Ellipsoid[{0, 0}, {3, 2}]}], ImageSize -> 10] gives me a tiny ellipse – eldo Jul 14 '17 at 17:17
• What @eldo means (I think) is that adding the option does have the effect stated in the documentation. Maybe there is an effect you're expecting that goes beyond what ImageSize does. You'd have to clarify that. – Jens Jul 14 '17 at 17:20

Maybe this is what you want?

scale = 0.1;

p1 = ListPlot[{{-0.4, -0.24}}, PlotStyle -> {GrayLevel[0.4], PointSize[0.09]}];
p2 = Graphics[{GrayLevel[0.4], Ellipsoid[{0.9, 0.6}, {3, 2} scale]}];

Show[{p1, p2}, PlotRange -> All, ImageSize -> 300] You have to scale / rescale the ellipsoid, not the total graphics!

And it might be useful to specify PlotRange and PlotRangePadding:

Grid[{Table[
Graphics[{GrayLevel[0.4], Ellipsoid[{0.9, 0.6}, {3, 2} scale]},
PlotRange -> {{-0.5, 2}, {-0.5, 2}},
