Hi, I have created a pcolor plot based on values that I have, I would like to extract the X, Y and C values into one table (preferably .txt or .csv), as I need to be able to open this data in GIS. I have been able to extract the data using the following code, but the problem I have is that it is three separate tables, is it possible to extract all three into one table?
hfig = openfig('myfig');
H = findobj(hfig,'type','surface');
x_data = get(H,'xdata');
y_data = get(H,'ydata');
c_data = get(H,'cdata');

Hi,
It is my understanding that you want to combine the data stored in variables x_data, y_data, c_data into a table and write that table to a .txt file.
Following is the code for the same.
X = [1 2 3; 1 2 3; 1 2 3];
Y = X';
C = [3 4 5; 1 2 5; 5 5 5];
hfig = pcolor(X,Y,C)
h = findobj(hfig,'type','surface');
x_data = get(h,'xdata');
y_data = get(h,'ydata');
c_data = get(h,'cdata');
T = table(x_data(:), y_data(:), c_data(:), 'VariableNames',{'X Data', 'Y Data', 'C Data'});
writetable(T,'MyFile.txt');
For more information, refer writetable.
