Hi @Markus
The issue occurs because the polar axes settings are not being maintained after plotting new data. When plotting new data with 'polarhistogram', MATLAB creates a new plot that resets all polar axes properties. To fix this, you should reconfigure the polar axes after plotting the dataAfter calling 'polarhistogram', reapply the custom axis configuration.
Here is the modified 'plotData' function, that reapplies the custom axis configureation:
function plotData(selectedDates)
str = get(dateList, 'String');
lc = numel(str);
am = get(dateList, 'Value');
selectedDate = get(dateList, 'String');
selectedIdx = get(dateList, 'Value');
if numel(selectedDates) <= 4
set(header, 'String', selectedDate(selectedIdx));
elseif numel(selectedDates) < lc
an = numel(am);
set(header, 'String', ['Histrogram - ', num2str(an), ' Päeva']);
elseif numel(selectedDates) == lc
selectedMonth = sheets{get(monthPopup, 'Value')};
set(header, 'String', selectedMonth);
end
% Plot histogram with specified bin count
angles = rand(1, 100) * 2 * pi; % Placeholder for actual data
polarhistogram(hPolarAxes, angles, 'BinEdges', linspace(0, 2*pi, 24)); % 23-24 bins
% Reapply the polar axes configuration based on the current radio button selection
selectedRadioButton = radioGroup.SelectedObject;
numDirections = str2double(selectedRadioButton.Tag);
configurePolarAxes(hPolarAxes, numDirections);
end
Replace the 'plotData' from 'testitesti.m' file with the above code. These changes maintain the cardinal direction labels (E, NE, N, etc.) instead of reverting to degrees when new data is plotted.
Regarding the incorrect graph plotting, you'll need to verify your actual wind direction data and binning logic, as the current code uses random placeholder data for 'angles' (angles = rand(1, 100) * 2 * pi).
Hope this helps!
