Hi. I have three columns of data. The first two columns are the x and y coordinates while the third one is the isoline column. Can anyone help me how to make a single contour plot in Matlab. I have attached the file here. Please help. Thanks.

filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1305315/contour%20plot%20data.txt';
opts = detectImportOptions(filename);
opts.DataLines = [9 Inf];
opts.VariableNames = {'x','y','IsoLevel'};
rawdata = readtable(filename,opts);
s=scatter(rawdata.x,rawdata.y,[],rawdata.IsoLevel);

You may try to use the dot as the marker and adjust the LineWidth property in order for the plot to look like a line.
s=scatter(rawdata.x,rawdata.y,[],rawdata.IsoLevel,'.','LineWidth',1);
