The MATLAB script below produces the following bar chart:
How do I remove the dot on the bars with zero error as I would like the bar to have no error calculated but the dot suggests there is 0% error for these readings.
x=categorical({'Q3','Q6','Q10','Q15','Q30','Q50'});
z=[2.891586318,1.99422657,1.907652812,4.71298388,6.007681496,6.718181667;3.229392123,3.36482536,4.089746011,5.204662107,6.761377397,7.978099976];
y=transpose(z);
a=[0.167797,0.314574,0.081018,0,0.116596,0;0,0.173132,0,0.231752,1.15677,1.204734];
errorplus=a;
errorminus=errorplus;
figure;
bar(x,y);
hBar = bar(y, 0.8);
for k1 = 1:size(y,2)
ctr(k1,:) = bsxfun(@plus, hBar(k1).XData, hBar(k1).XOffset');
ydt(k1,:) = hBar(k1).YData;
end
hold on
errorbar(ctr, ydt, errorplus, '.k')
hold off
ylabel('Signal Intensity','FontSize',18)
set(gca,'linewidth',2,'FontSize',14)
ylim([0 10]);
set(gca,'XTickLabel',cellstr(x))

You are telling MATLAB to set color to black and marker to dot.
'.k'
Replace it with
'k'
Also set linestyle of errorbar to 'none'.

By including this command at the end?
errorbar.LineStyle = 'none';

within errorbar command like
errorbar(ctr, ydt, errorplus,'k','LineStyle','none')
to call it by
handle_errorbar.LineStyle
you have to save errorbar handle in some variable just like you save hbar. and you have to set LineStyle to none for each error bar in that case. so it is better the first way
