RE: Re: GraphicsArray: same width, different height ? 360deg-fly around a surface

That's nice Jens, but now the z scale is different for the two plots.

Similar problems also occur with a two rectangle approach. I believe that
GraphicsArray should be used less often than it is, mainly when one wants to
assemble a series of plots that have the same overall plot ranges, but
different sets of data.

If one wants to directly compare two curves or surfaces, it is better to
render them in the same plot.

Hi,

fix the AspectRatio to the same value for both plots, i. e.,

table1 = ListPlot3D[Table[Sin[x*y], {x, 0, (3*Pi)/2, Pi/15},
     {y, 0, (3*Pi)/2, Pi/15}], PlotRange -> {0, 0.25},
    Axes -> {None, None, None}, ViewPoint -> {5, -2.5, 0.6},
    BoxRatios -> {10, 10, 1.25}, AspectRatio -> 1/2];
table2 = ListPlot3D[Table[Sin[x*y], {x, 0, (3*Pi)/2, Pi/15},
     {y, 0, (3*Pi)/2, Pi/15}], PlotRange -> {-1, 0},
    Axes -> {None, None, None}, ViewPoint -> {5, -2.5, 1},
    BoxRatios -> {10, 10, 5}, AspectRatio -> 1/2];

Regards
