I have a while loop inside of which I have to use a plot and a chasePlot function.

The problem is, it comes up with a new window figure each time the loop runs. I somehow want a single frame which can be updated rather than each time making a new window and figure for it.

Anybody knows how to prevent a new figure in each loop so that one figure is there and that keeps on updating.

If you have a handle to the axes you are using you can pass it to the 'Parent' property of the chasePlot when you construct it.

Something like:

hAxes = axes
chasePlot(scenario, 'Parent', hAxes)

You'll probably want to do something like this (ultimately)

% set working figure to figure 1 (creating if it doesn't exist)
figure(1);
% get current axes (creating if it doesn't exist)
hAxes = gca;
% pass it to the chase plot.
chasePlot(passingCar,'Parent',hAxes)

If you call axes() you may end up creating a new one each time and just rendering it over the previous axes.

Thank you. This works as well but I am using axes only because it gives me a good view of plot in plot. Though I don't know exactly how the output differs if I use
