How to convert MATLAB plots to xls (Excel) sheets ?

4 次查看(过去 30 天)
I have almost ten to fifteen MATLAB figures which I've got by running a MATLAB code. The code takes hours to plot a figure. My professor has now asked me to make .xls (Excel) sheets from the data associated with these figures. Although, I know how to do it and that is by using the "xlswrite" command, but, really ?, I have to run the code for hours again? Can anybody recoomend me an easy way using which I could get data files directly from the MATLAB figures ?

You can access data of a plot with the line handle. For instance :
% Current figure handle (or use openfig if you saved the figure in a FIG-File)
hFigure = gcf;
% Find line handle
hLines = findobj(gcf, 'Type', 'Line')
% Here are your data
hLines.XData
hLines.YData
In this example, I assume you have only one line in each plot.
Since R2019a, prefer writetable, writematrix, or writecell instead of xlswrite

Here you go
% Current figure handle (or use openfig if you saved the figure in a FIG-File)
hFigure = gcf;
% Find lines handles
vhLines = findobj(gcf, 'Type', 'Line');
% X data, I assume it's the same for all lines (otherwise use interp1)
vX = vhLines(1).XData;
% All Y data
mY = vertcat(vhLines.YData)';
% All names
cNames = {vhLines.DisplayName};
% Cell to export
cToExport = [
't [s]', cNames; % Headers
num2cell([vX', mY])];
% Write into file
xlswrite('YourWorkbook.xlsx', cToExport, 'YourSheetName')
