Extracting y-data from ezplot.
显示 更早的评论
Dear everyone
I've created a plot using ezplot, and I want to extract the ydata. Now I have used the get(object,'YData'), but all I get are the y-axis values. I'm doing the following:
cd=ezplot('1.5*x.^.56*y.^.44=1', [0 6 0 6]);
And then something like:
y=get(cd,'YData');
But all I get is values from 0 to 6, not the shown y-values in the figure! In essence I need all the (x,y)-pairs in the interval (0 excluded)
Thanks in advance Patrick

Hi,
you need to get the contourMatrix:
bla = ezplot('1.5*x.^.56*y.^.44=1', [0 6 0 6]);
tmp = get(bla,'contourMatrix');
figure
plot(tmp(1,:),tmp(2,:))
set(gca,'ylim',[0 6])
Small note: Don't name a variable, e.g. "cd" like a MATLAB function.

Hi,
I ran
bla = ezplot('1.5*x.^.56*y.^.44=1', [0 6 0 6]);
And then did a get(bla) to see what are the properties and what is stored in them. Since there aren't much properties which contain any numerical data it didn't took long to figure out that the data is stored under the contourMatrix property.
