How to do a line plot with four variables?
显示 更早的评论
I have four variables in excel sheet , time, temp, lat and lon. I have to plot temperature data (which is on different grids i.e. lat, lon as in excel sheet). I want to take number of grids longitude 1 to 144 and latitude 1 to 73. And on this grid I have to plot temp data. I am not so perfect in MATLab. I have tried a lot but I am not getting how to do it. I've tried some commands like geoshow, load topo, m_map , but not succeeded. Kindly, help me. I've attached the excel sheet with this.
Thanks and Regards

I'm not sure how you want to handle the year (column 1), but this is what I have so far:
[numbers, txt, raw] = xlsread('book1.xls');
temp = numbers(:, 2);
x = numbers(:, 3);
y = numbers(:, 4);
% Create an image
myTempImage = zeros(max(y), max(x));
for row = 1 : length(x)
% Assign temperature at row y, column x:
myTempImage(y(row), x(row)) = temp(row);
end
imshow(myTempImage, [], 'InitialMagnification', 1600);
axis on;
myColorMap = jet(256);
myColorMap(1,:) = [0,0,0];
colormap(myColorMap);
colorbar;
