I would like to add different colors in an interactive geobubble graph

Hi,

I am trying to do an interactive goebubble graph where plots CO2 emissions (data) from a excel table. The excel containes: company, latitude, longitude, activity and emissions.

I created a listbox with uicontrol in which you can choose the Activity and then the geobubble graph shows the emission from the companies under this activity. I did that you can choose multiple activities and I would like to assign different colors in those activities in the geobubble graph.

If anyone could help or advise me. I would appreciate it.

Thank you.

I leave the code here. I am not really good at programming so it will probably need a lot of corrections.

% Read data from Excel file and create Table in matlab
t = readtable("file.xlsx");
% Extract the columns of data you want to use
latitude = t.latitude;
longitude = t.longitude;
emissions = t.emissions;
activity = categorical(t.activity);
% Create a figure
f = figure;
% Create a listbox menu to choose the category
categories = unique(activity);
lb = uicontrol('Style', 'listbox',...
    'String', categories,...
    'Min', 0, 'Max', 2,...
    'Position', [20 340 100 150],...
    'Callback', @changeCategories);

changeCategories(lb, []);

% Callback function for listbox
function changeCategories(lb, ~)
selectedCategories = categories(lb.Value);
idx = ismember(activity, selectedCategories);
geobubble(latitude(idx), longitude(idx), emissions(idx),'SizeLegendTitle','Emissions CO2 [kt]');
title('CO2 Emissions in Sweden by activity: ');

end

Here is the code that shall give different colors:

% Read data from Excel file and create Table in matlab
t = readtable("file.xlsx");
% Extract the columns of data you want to use
latitude = t.latitude;
longitude = t.longitude;
emissions = t.emissions;
activity = categorical(t.activity);
% Create a figure
f = figure;
% Create a listbox menu to choose the category
categories = unique(activity);
lb = uicontrol('Style', 'listbox',...
    'String', categories,...
    'Min', 0, 'Max', 2,...
    'Position', [20 340 100 150],...
    'Callback', @changeCategories);
changeCategories(lb, []);
% Callback function for listbox
function changeCategories(lb, ~)
    selectedCategories = categories(lb.Value);
    ACT = categorical(t.actvity);
    idx = ismember(activity, selectedCategories);
    geobubble(latitude(idx), longitude(idx), emissions(idx),'SizeLegendTitle','Emissions CO2 [kt]', ...
        ACT);
   title('CO2 Emissions in Sweden by activity: ');  
end

I got this error:

Error using geobubble

Expected colordata to be one of these types:

categorical

I have fixed it. But thank you so much for your input.
