(* a simple plot, turns out nice *)
t1 = Plot[x^2,{x,-5,5}];
Export["/tmp/test1.png", t1, ImageSize -> {800,600}];
(* let's add a legend, turns out small *)
t2 = Plot[x^2,{x,-5,5},PlotLegends -> {"x^2"}]
Export["/tmp/test2.png", t2, ImageSize -> {800,600}]
(* if we make image bigger, plot still turns out small *)
t3 = Plot[x^2,{x,-5,5},PlotLegends -> {"x^2"}]
Export["/tmp/test3.png", t3, ImageSize -> {800*2,600*2}]
test1.png from the above looks very nice and uses up the entire 800x600 canvas:
test2.png's plot uses up only a fraction of the 800x600 canvas:
test3.png has a larger canvas (2 times larger in each direction), but the plot is exactly the same size as in test2.png:
I'd at least expect it to be two times bigger in each direction, even if it didn't use up the entire 1600x1200 canvas. My hope for test3.png was to create a larger image that didn't fill the canvas and then use ImageMagick to crop.
Why does this PlotLegends problem occur and how can I fix it?
I've skimmed similar questions on this site, but I don't think any address this issue exactly. Several of these questions suggest "homebrew" solutions, which I'd prefer to avoid if at all possible.
