MATLABでデータを取得して、GUIにあるaxesの全て、もしくは指定した複数のaxesにグラフを描画したい場合があったので作成しました。
環境
Windows10 64bit
MATLAB R2016a 64bit
躓いた点
forループの中でaxesのオブジェクト名を検索、指定すると1回目は描画できるが、2回目以降はオブジェクトが見つからずに描画できませんでしたが、forループの外で全てのaxesオブジェクトを取得することで解決しました。
各axexのオブジェクト名は、GUIDEで確認できます。
今回は、標準の状態なのでaxes1~axes10となります。
for i = 1:10 x = 0 : i * pi / 100 : rand * pi; str = strcat('axes', num2str( i )); str h = findobj('Type', 'axes', 'Tag', str); h axes( h ); plot(sin(x)); end
実行結果

解凍して、下記のMファイルと同じディレクトリに置いてください。
