MATLAB: Determine if using HG2

r2014bgraphics

How can I determine if MATLAB or the current figure is using the new graphics pipeline, HG2? I need a function

   tf = ishg2(figure_handle)

which should be backwards compatible, say to MATLAB 7.0, and also account for the fact that people can choose which rendering pipeline to use (HG1 or HG2) in newer MATLAB releases, so simply checking version number is not sufficient.

I've ended up using the undocumented function, graphicsversion():

function tf = ishg2(fig)
try
    tf = ~graphicsversion(fig, 'handlegraphics');
catch
    tf = false;
end

MATLAB: What is best practice to determine if input is a figure or axes handle

Simples, write those functions yourself, something along the lines:

function OK = isfigure(h)
if strcmp(get(h,'type'),'figure')
  OK = 1;
else
  OK = 0;
end

You could decorate your code to handle array input, do error checking and make the output proper Boolean output but the core part is to look at the type field of the graphics handle.

MATLAB: How to get the object handle

The value of 'Children' properties are always object handles (usually in handle graphic numeric form), and are never strings.

Is 'axes_of_data' a variable name, or is it a field in your handles structure, or is it the Tag of the axes? (The last two could potentially be both true, especially if you are using GUIDE.)

If it is a Tag, then use

h = findobj(gcf, 'Tag', 'axes_of_data')
