Geodensityplot help in matlab

Hi,

New here. Trying to do a densityplot of the UK but keep running into problems.

using:

Data = readtable('Work11.xlsx');

figure

latAll = Work11.latitude;

lonAll = Work11.longitude;

weight = Work11.Normalized

geobubble(latAll,lonAll,weight,'FaceColor','interp')

I get:

The problem is, well, the big blue regtangle. I am sure this has to do with Amin min and max, but any attempt to adjust these values causes errors in the results.

Any ideas?

Thanks

Hi @Liam Lincoln,

I understand that you are trying to create a density plot for the UK using geographical data with `geobubble` in MATLAB. Ensure you are accessing your table data correctly and using `geobubble`'s functions properly.

Here’s how you can adjust your code:

% Load data from Excel file
Data = readtable('Work11.xlsx');

% Extract columns for latitude, longitude, and weight
latAll = Data.latitude;
lonAll = Data.longitude;
weight = Data.Normalized;

% Create a geobubble plot
figure;
geobubble(latAll, lonAll, weight);
title('Density Plot of the UK');

Ensure your latitude and longitude data are accurate and within the UK's geographic bounds. If you encounter a big blue rectangle, it might be due to outliers or incorrect data ranges. Use `geolimits` to focus the map on the UK:

geolimits([49 61], [-8 2]); % Adjust as necessary

I hope this helps!
