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

function varargout = test(varargin)
% TEST MATLAB code for test.fig
% TEST, by itself, creates a new TEST or raises the existing
% singleton*.
%
% H = TEST returns the handle to a new TEST or the handle to
% the existing singleton*.
%
% TEST('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TEST.M with the given input arguments.
%
% TEST('Property','Value',...) creates a new TEST or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before test_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to test_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
