Deleting data from a graphics
显示 更早的评论
Hi all,
I have two variables,x and y.
There are 100 data in these variables,plotting graphics with plot function
After manually deleting some data in the chart, the number of data automatically decreases to 100 in x and y.
How can I save the current data back to the workspace section after deleting it?
Thank you

figure
hold on
for i = 1:10
h = plot(x(i),y(i),'.r') ;
end

%% Get data
a = get(gca,'Children');
xdata = get(a, 'XData');
ydata = get(a, 'YData');
zdata = get(a, 'ZData');
xdata = cell2mat(xdata) ;
ydata = cell2mat(ydata) ;
plot(xdata,ydata,'Ob')
