How to set scale range for a contour?

2 views (last 30 days)
Hello,
I am trying to plot a contour from excel data with two colums. Is their any way to set the scale of both the axis in the data range and with label? I am attaching the contour plot i have obtained, I didnt understand why the x axis is from 1:2. Can some one please help me. Thanks in advance.
My code:
data = readtable('Abb73at42.xlsx');
dataArray = table2array(data);
contourf(dataArray);

The x-axis goes from 1 to 2 because the contour plot is of a (117x2) matrix. That also explains the range of the y-axis.
data = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/736719/Abb73at42.xlsx')
data = 117×2 table
X Y _______ ______ -69.793 1.3879 -69.635 2.4547 -69.537 3.4459 -69.432 4.904 -69.352 6.4546 -69.334 7.5779 -69.161 9.0059 -68.937 10.381 -68.975 11.324 -68.975 12.41 -68.975 13.496 -68.889 14.557 -68.548 16.102 -68.435 17.943 -68.376 19.148 -68.172 20.606
figure
plot(data.X, data.Y)
grid
xlabel('X')
ylabel('Y')
More importantly, what information do you want to get from a contour plot of these data? That could provide an approach to getting a useful result.
