test: Fix 4 failing plot demos. * scripts/plot/legend.m: Demo #11, use 'h' for returned handle. * scripts/plot/plot.m: Fix typo "lenths" -> "lengths". * scripts/plot/ribbon.m: Remove unnecessary call to meshgrid now that sombrero returns meshgridded data. * scripts/plot/trimesh.m: Set colormap so plot is always reproducible.
