重ね合わせることができる2つの図を保存するMatlab

Question

2つのMATLAB数値をpngとして保存しています。完全に重ね合わせるために同じサイズにします。

最初の図は、2つの色で半分に分割された円である 'FilledCircle2'関数によって計算されます。 2番目の数字は、関数 'FilledCircle2'によって計算された円の左半分である関数 'FilledCircleL'によって計算されます。

私は同じサイズの2つの図形を持ちたいので、完全に重ねることができます。 誰かが私が間違っていることを理解するのに役立つことができますか？

機能とそれぞれの出力の両方に、自分のコードであります機能の出力HalfFilledCircleL(0,0,10,300, 'r')：

Answer 1

軸のxy限界を設定するのに使用xlimとylim：

figure; 
HalfFilledCircleL(0,0,10,300, 'r'); 
xlim([-12 12]);ylim([-12 12]); 
az= -90; %azimuth, az, is the horizontal rotation about the z axis as measured in degrees from the negative y-axis. Positive values indicate counterclockwise rotation 
el= 90; % vertical elevation of the view point in degrees 
view(az,el); 

figure; 
FilledCircle2(0,0,10,300, 'y', 'r'); 
xlim([-12 12]);ylim([-12 12]);
