Helper Function: Plot the Plot Types

callback functions. Because of this,

localUpdatePlot has access to the same

data and component handles.

function localU pdat ePlot

% Helper function for plott ing the selected pl ot type

mPlotTypes{get(hPlotsPopupmenu, 'Value'), 2}(hPlotAxes );

end

The localUpdatePlot function uses the pop-up menu Value property to

identify the selected menu item from the first column of the

mPlotTypes

5-by-2 cell array, then calls the corresponding anonymous function from

column two of the cell array to create the plot in the axes.
