Hello, I am currently trying to plot 3 axis-acceleration data dynamically in Matlab in 3 subplot figures. The code is
subplot(3,2,2)
hp1 = plot(1, c1(1, 1),'--rs','LineWidth',1,...
'MarkerEdgeColor','k',...
'MarkerFaceColor','r',...
'MarkerSize',3);
axis([ 0,ceil(nFrames*1.03),-6,6]);
title('Acceleration Data in X Axis')
hold on
subplot(3,2,4)
hp2 = plot(1, c2(1, 1),'--rs','LineWidth',1,...
'MarkerEdgeColor','k',...
'MarkerFaceColor','g',...
'MarkerSize',3);
axis([ 0,ceil(nFrames*1.03),-6,6])
title('Acceleration Data in Y Axis')
hold on
subplot(3,2,6)
hp3 = plot(1, c3(1, 1),'--rs','LineWidth',1,...
'MarkerEdgeColor','k',...
'MarkerFaceColor','b',...
'MarkerSize',3);
axis([ 0,ceil(nFrames*1.03),-6,6])
title('Acceleration Data in Z Axis')
hold on
for k = 2 : nFrames
set(hp1, 'XData', k, 'YData', c1(k,1));
set(hp2, 'XData', k, 'YData', c2(k,1));
set(hp3, 'XData', k, 'YData', c3(k,1));
pause(0.03)
end
I found hold on function doesn't work based on this case since I want to retain each point on the figure rather than only plotting the current one.
Does any one know how to solve that problem?
Thanks,
Joe

Try
set(hp1, 'XData', [get(hp1, 'Xdata'); k], 'YData', [get(hp1,'Ydata'); c1(k,1)]);

Have you tried "hold all"?
