How to edit each interval web in a spider plot for different categories?

Is there a way I can edit the intervals of each of the 5 categories. They are all not spaced out the same nor evenly. For example 0, 20, 40, 60, 80, 100 for one category, then <0.85, 1.00, 1.20, 1.30, >1.35 for the next, etc for the next three categories?

D1 = [0.828 0.187 000.0 3.710 25.00]; %Min Values
D2 = [1.260 0.171 142.0 1.190 75.00]; %Data Points
D3 = [1.50 0.046 180.5 0.250 100.0]; %Max Values
P = [D1; D2; D3]; 

axesLimits = [0.828 0.046 000.0 0.250 25.00; %minimum values for spider graph 
 1.50 0.187 180.5 3.710 100.0]; %maximum values for spider graph

Hi,

xticks and xticklabels functions in MATLAB to customize the intervals and labels for each category. You can define custom intervals for each 5 categories and then use xticks to set the tick positions on the x-axis and xticklabel functions to set corresponding labels respectively.

This example might be helpful

D1 = [0.828 0.187 000.0 3.710 25.00]; % Min Values

D2 = [1.260 0.171 142.0 1.190 75.00]; % Data Points

D3 = [1.50 0.046 180.5 0.250 100.0]; % Max Values

P = [D1; D2; D3];

% Define the custom intervals for each category

intervals = {[0, 20, 40, 60, 80, 100], ...

[0.85, 1.00, 1.20, 1.30, 1.35], ...

% Define custom intervals for the remaining categories

% ...

};

% Define the labels for each interval

labels = {'Category 1', 'Category 2', 'Category 3', 'Category 4', 'Category 5'};

% Plot the spider graph

theta = linspace(0, 2*pi, size(P, 2)+1);

theta = theta(1:end-1);

figure;

polarplot(theta, P(1,:), '-o');

hold on;

polarplot(theta, P(2,:), '-o');

polarplot(theta, P(3,:), '-o');

thetaticks(rad2deg(theta));

thetaticklabels(labels);

Hope it helps!

I am using the spider_plot toolbox (spider_plot_R2019b) to create this graph. I cannot seem to find a way to edit the web intervals. Here is how it looks like. I will attach the rest of the code.

% Spider plot 
s = spider_plot_R2019b(P,... 
 'AxesLabels', {'Stride Length (m)',... %1 
 'Postural Sway Area, ECUB',... %2 
 '360-degree Turn Peak Velocity (degrees/sec?)',... %3  
 'Sit to Stand Duration (s)',... %4 
 'Confidence (%)'},... %5  
 ... 
 'AxesInterval', 5,... %number of sections/levels within the spider graph 
 'AxesPrecision', 2,...
 'AxesDirection', {'normal', 'reverse', 'normal', 'reverse', 'normal'},... %THE MOST IMPORTANT LINE OF CODE  'FillOption', {'on', 'on', 'off'},... %fill option (red, black, green) 
 ... 
 'Color', [.9 0 0; 0 0 0; 0 .8 0],... %(red, black, green) 
 ... 
 'FillTransparency', [1, 1, 1],'AxesLimits',axesLimits); %transparency level of fill (1 is the highest) title('Data Visualization of Patient') %title 
legend('Lowest Possible', 'Patient X', 'Highest Possible', 'Location', 'northwestoutside'); %legend

Hi,

You can modify the 'AxesInterval' parameter. In the above code, it is set to 5, which means there are 5 sections/levels within the spider graph. You can adjust this value to change the number of intervals.
