I need help adjusting the axis on a theta-S contour plot

I'm having a difficult time finding area where I can adjust the axis. When I plot the data they are clustered at the bottom making it difficult to see. I have tried adjusting these three sections but nothing has been working. Any suggestions? Thank you!

% Adjusting xdim and ydim for smaller scale

xdim = round((smax - smin) ./ 0.05 + 1); % Decrease increment to 0.05

ydim = round((thetamax - thetamin) + 1);

% Adjust contour levels (decrease the scale)

contour_levels = 20:5:37; % Change the range as needed $$$$PAY Attention

[c, h] = contour(si, thetai, dens, contour_levels, 'k'); % Contour lines

clabel(c, h, 'LabelSpacing', 100);

% Adjusting x and y axis limits for scaling

xlim([smin, smax]); % Set limits for x-axis

ylim([thetamin, thetamax]); % Set limits for y-axis

end

You forgot to attach the data and a working example so folks could see what you're talking about (and then try to do something about it...)

Hi Kelly,

The attached data has an outlier value of Potential_Temperature_C as 65535 at the first index which is much bigger than the other values. This results in scaling up of the plot to accommodate that value.

Plot with all the values:

plot(MAST402HW02Data2.Salinity,MAST402HW02Data2.Potential_Temperature_C,'.','MarkerSize',10);

Plot skipping the first value:

plot(MAST402HW02Data2.Salinity(2:end),MAST402HW02Data2.Potential_Temperature_C(2:end),'.','MarkerSize',10)

Consider omitting the value or replacing it, hope this helps!
