Can you please elaborate more on the data used to generate the figure?

Hi Devendra, i understand that you are to make a plot same as above mentioned figure. This can be done by creating a bar plot in MATLAB with respect to the y-axis (i.e., horizontal bars) and having different legends for each group of bars can be achieved using the barh function for horizontal bar plots, and grouping the data appropriately.

Please find the below attached code for the same:

% Sample range data for 3 categories, each with start and end values for 4 groups

dataStart = [1, 2, 3, 4; 4, 5, 6, 7; 7, 8, 9, 10]; % Start of range for each group

dataEnd = [2, 3, 4, 5; 5, 6, 7, 8; 8, 9, 10, 11]; % End of range for each group

% Categories for the y-axis

categories = 1:3; % Numeric categories for plotting

% Group labels (for legend)

groups = {'Group 1', 'Group 2', 'Group 3', 'Group 4'};

figure; % Create a new figure

hold on; % Hold on to plot multiple lines

[numCategories, numGroups] = size(dataStart);

% Colors or markers for each group - adjust as needed

colors = lines(numGroups); % Generate distinct colors

% Array to hold plot handles for legend

h = zeros(1, numGroups);

% Plotting ranges

for i = 1:numGroups

% Plot each range for the group, only need to add one line per group to the legend

for j = 1:numCategories

% Plot each range as a line segment

lineHandle = plot([dataStart(j,i), dataEnd(j,i)], [categories(j), categories(j)], ...

'Color', colors(i,:), 'LineWidth', 10);

if j == 1

% Save the handle for the first line of each group for the legend

h(i) = lineHandle;

end

% Adjusting the plot

set(gca, 'ytick', categories, 'yticklabel', arrayfun(@num2str, categories, 'UniformOutput', false));

ylim([0, numCategories + 1]); % Adjust y-axis limits

% Create legend using handles to the first line of each group

legend(h, groups, 'Location', 'northeastoutside');

xlabel('Value'); % Label for the x-axis

ylabel('Category'); % Label for the y-axis

title('Range Representation for Each Category and Group'); % Title for the plot

hold off; % No more plots on this figure

Please take a look at the horizontal bar graph documentation for better understanding: https://www.mathworks.com/help/matlab/ref/barh.html

I hope this helps!

Thank you for your kind suggestion. I could do it with the help of available help on mathworks. But I could not increase the length of horizontal bar till the end of right y axis. Please suggest me how to increase the length of horizonatl bars.

I appreciate your kind cooperation.
