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.
https://www.mathworks.com/matlabcentral/answers/420926-bar-plot-with-error-bar#answer_338593
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');
