MATLAB: How to draw Interval animation

animationgraph

Hi I'm trying to plot a graph of y=x, y=-x, y=0, x=0

and a ball on each plot goes back and forth interval of -1 to 1.

I've been searching internet to see any similar animation but failed to find any.

Can someone give me an advise on how to even draw a ball model that oscillate?

Thank you

One possibility:

x = linspace(-1, 1, 75);
y = -x.^2;
figure(1)
for k2 = 1:2
    for k1 = 1:length(x)
        plot(x(k1)*(-1)^k2, y(k1), 'ob', 'MarkerFaceColor','r')
        axis([min(x)  max(x)    min(y)  max(y)])
        refreshdata
        drawnow
    end
end

It redraws the plot for each position of the ball. Experiment to get the result you want. See the documentation for the various functions for the details of how it works.

Define a figure CloseRequestFcn like below

function my_closereq(src, callbackdata)
selection = questdlg('Close This Figure?',...
    'Close Request Function',...
    'Yes','No','Yes');
switch selection
    case 'Yes'
        delete(gcf);
    case 'No'
        return
end
end

And use this script

x = linspace(-1, 1, 75);
y = -x.^2;
fig = figure('CloseRequestFcn', @my_closereq);
ax = axes(fig);
while true
for k2 = 1:2
    for k1 = 1:length(x)
        plot(ax, x(k1)*(-1)^k2, y(k1), 'ob', 'MarkerFaceColor','r')
        axis([min(x)  max(x)    min(y)  max(y)])
        refreshdata
        drawnow
    end
end
end

Hope this helps!
