I am trying to plot a bar graph of mean and standard deviation data for an assay with 8 conditions. I can't plot the error bars using the errorbar function. The script (below) works in 2014a. How can I modify the code to work in 2015a?
figure
hold on
bar(Inv_Freq_Mean)
errorbar(1:8,Inv_Freq_Mean, Inv_Freq_Std)

That certainly looks like it should work in 2015a. Can you tell me more about what's not working? Is there an error message? Does something draw incorrectly?

This is one way:
[data,ctrs] = hist(randn(50,2), 10);
figure(1)
hBar = bar(ctrs, data);
ctr1 = bsxfun(@plus, hBar(1).XData, [hBar(1).XOffset]');
ctr2 = bsxfun(@plus, hBar(2).XData, [hBar(2).XOffset]');
ydt1 = hBar(1).YData;
ydt2 = hBar(2).YData;
hold on
errorbar(ctr1, ydt1, ones(size(ydt1))*0.4, '.r')
hold off
Credit goes to Kelly Kearney for discovering it.
