Hi everyone,
I am going to plot contour line maps using the code below. My problem is that some contour numbers can not be distinguished in some of the plots. Is there any way to adjust plots' resolution so that one can read contour numbers without any difficulty?
clear
close all
clc
load('POFDE.mat');
data = cell2mat(POFDE);
[lat,lon] = meshgrid(unique(data(:,1)),unique(data(:,2)));
for i = 1:(size(data, 2)-2)
figure
I = scatteredInterpolant(data(:,[1 2]), data(:,i+2));
contourf(lon,lat,min(1,max(0,I(lat,lon))),'ShowText','on')
colorbar
title(['The probability of frost depth exceedance of \Omega_{\delta} = ' num2str(i) ' feet'])
exportgraphics(gca, sprintf('FrostPlot_%d_feet.png', i))
end

You can zoom in the portion of the contour plot where you want the contour labels better resolved, e.g.,
openfig untitled.fig
ans =
Figure (1) with properties: Number: 1 Name: '' Color: [1 1 1] Position: [680 558 560 420] Units: 'pixels' Show all properties
