How can convert line plot to bar plot

Hi everyone

I have code for a line plot, but I'd like to convert it to a bar plot, for example, for GR with 50 and 100 nodes, two bars adjust together under the same name, GR, and so on for other algorithms:

nodeSize=[50 100]
figure;
x = sort([energyConsumption_GR; energyConsumption_UGR; energyConsumption_CUC], 'descend');
hold on;
plot(nodeSize, x(1, :)', '-', 'LineWidth', 2);
plot(nodeSize, x(2, :)', '--', 'LineWidth', 2);
plot(nodeSize, x(3, :)', '-.', 'LineWidth', 2);
xlabel('# Nodes');
ylabel('J');
legend({'GR','UGR','CUC'}, 'Location', 'northwest');
title('ECC');
whitebg('white');
grid on;

I would to be like this graph:

I have try like this but give me one bar for each algorithm, How can I add next each bar the results of 50 nodes?

node=100;
x = sort([energyConsumption_GR; energyConsumption_UGR; energyConsumption_CUC], 'descend');
hold on;
bar(1, x(1), 'FaceColor', '#0072BD', 'BarWidth', 0.2);
bar(2, x(2), 'FaceColor', '#D95319', 'BarWidth', 0.2);
bar(3, x(3), 'FaceColor', '#EDB120', 'BarWidth', 0.2);

ylabel('J');
title('Energy Consumption, # Node= 100');
set(gca,'XTick',[1 2 3]);
set(gca,'XTickLabel',{'GR','UGR','CUC'});
whitebg('white');
grid on;

[energyConsumption_GR; energyConsumption_UGR; energyConsumption_CUC] -- are those scalars or vectors or ...?

I have no idea what you want to do.

Perhaps something like this —

nodeSize=[50 100];
x = rand(3,2);

figure
hb = bar(x, 'FaceColor','flat', 'BarWidth',0.2);
% hb(1)
% hb(2)
hb(1).FaceColor = '#0072BD';
hb(2).FaceColor= '#D95319';
ylabel('J');
title('Energy Consumption, # Node= 100');
set(gca,'XTick',[1 2 3]);
set(gca,'XTickLabel',{'GR','UGR','CUC'});

I also have no idea what ‘nodeSize’ does here.

Thank you so much, yes this is right.

As always, my pleasure!

It appears you're looking for

bar(x)

or

bar(x.')

depending on how you'd like to group the bars.
