在 MATLAB Online 中打开

You can set each axes as the current axes with the axes commands:

axes(handleToAxes1);
plot(x1, y1);
axes(handleToAxes2);
plot(x2, y2);
axes(handleToAxes3);
plot(x3, y3);

Or send in the axes handle in to the function - most of them take an axes handle as an input argument:

plot(handleToAxes1, x1, y1);
imshow(imageArray, 'Parent', handleToAxes2);
bar(handleToAxes3, x3, y3);

You can use subplot() when you create your 5 graphs, and store the returned handles for each set of axes in your GUI. Then, when you push the button, pass the desired axes handle into plot (as the first parameter) to draw on those axes.
