figure.fig

I have some data which comes from some graphs similar in shape to normal distribution curve. I have a MATLAB code which analyzes these graphs, find the peak position of each graph, and then plot the data of the peak positions and save the peak positions graph as a .fig file similar to the attached file.

But I want to get this peak positions data and want to plot in OriginPro. Can anyone help me how to extract this data? I found some solutions on the internet but those solutions only work for the simple graphs.

Hi,

For you case, you can try.

uiopen('figure.fig');
axes = gca;
dataObj = axes.Children; %give you the object containing data, if there are multiple lines, dataObj will be an array.
xData = dataObj.XData;
yData = dataObj.YData;
