How to align the x axis of bar graphs in R2018b

The bar plots in the Matlab version 2018 doesnot align with the x - axis labels as was in the previous version. How can this be corrected? Attached plots from both versions for reference.

Version 2017:

Version R2018b:

Interesting. Could you share the code you use to create the figure? I created a simple example in 2018b and it looks aligned to me.

Hello Cris,

Below is an extract of the code. There has been no changes to the code, only an upgrade of the matlab version. Look forward to your feedback.

Thanks

Turbocharger_rpm_dev_trend =[1 2 3 1 2 3 ; 2 1 3 2 2 1];
Scavenge_pressure_dev_trend = [1 1 2 1 2 3];
Compare_months = {'May','Jun','Jul','Aug','Sep','Oct'};

h_ax(1) = subplot(211);
bar(Turbocharger_rpm_dev_trend','barwidth', 0.5);
ylabel('%','FontSize',10)
title('T/C rpm deviation from nominal')
legend('T/C # 1','T/C # 2','Orientation','horizontal')
set(gca,'xtick',[1:length(Compare_months)],'xticklabel',Compare_months)
grid on

h_ax(2) = subplot(212);
bar(Scavenge_pressure_dev_trend, 'FaceColor',[0 .5 .5],'barwidth', 0.5);
ylabel('bar','FontSize',10)
title('Scavenge pressure deviation from nominal')
set(gca,'xtick',[1:length(Compare_months)],'xticklabel',Compare_months)
grid on

Hello Chris,

Any update? Appreciate your input.

I can't explain why behavior has changed, but I see what is happening. The xlim of your plots is different.

• xlim - T/C rpm: [ 0.5571 6.4429]
• xlim - Scavange pressure: [-0.0500 7.0500]

There are two ways around it that I've tested.

1. Set xlim to be the same in both plots: xlim([0,7])
2. include the months as the X variable when you call the bar function.

m = categorical({'Apr','May','Jun','Aug','Oct','Nov'});
Compare_months = reordercats(m,{'Apr','May','Jun','Aug','Oct','Nov'});
...
subplot(211);
bar(Compare_months,Turbocharger_rpm_dev_trend','barwidth', 0.5);
ylabel('%','FontSize',10)
title('T/C rpm deviation from nominal')
legend('T/C # 1','T/C # 2','Orientation','horizontal')
grid on

Thank you Chris.
