Hi guys
I have a bar chart and I want to add a error bar. But I dont know how to do that.
I have added my data set and this is my bar chart:
figure();
scaleSelection = strcmp(scale,'like'); % use strcmp(), not "==".
barData = meanVariantsVelocity(scaleSelection);
bh = bar(barData);
bh.FaceColor = 'flat';
% Find which bars have velocity==50
velocitySelection = velocity == 50;
velocityBarIdx = ismember(find(scaleSelection), find(velocitySelection));
% Choose two colors
barColors = [0 0 1; 1 0 1];
% Color the vel=50 bars
cmap = barColors(velocityBarIdx+1,:);
bh.CData = cmap;
[vgroup, vg] = findgroups (clean_ds.variants);
title = ('like');
% % add x tick labels
ax = bh.Parent;
ax.XTick = 1:numel(barData);
ax.XTickLabel = vg;
ax.TickLabelInterpreter = 'none';
xtickangle(ax, 45) % or try 90 degrees
my title is also not working.
Do you guys can help me?

Here's a simple demo you can follow to add errorbars to your bar plot.
If you get stuck applying that demo, share what you've got and I'd be happy to get you over the hump.
To fix the title problem
title('like'); % not title = ('like');
