回答： Walter Roberson 2023-10-23

Hello,

I have this bar chart, and I need that the xticklabels (the days) have to be aligned along horizontal line. I need, that the days start at the same horizontal line. The days are defined as categorical values:

Xday1=categorical({'Jan.3','Jan.4','Jan.12','Jan.13','Feb.23','Feb.24','Mar.1','Mar.2','Apr.6', ...
 'Jun.12','Jun.16','Jul.12','Jul.13','Oct.5','Oct.27','Oct.28','Oct.29','Nov.19','Nov.20'});
Xday1=reordercats(Xday1,{'Jan.3','Jan.4','Jan.12','Jan.13','Feb.23','Feb.24','Mar.1','Mar.2','Apr.6', ...
 'Jun.12','Jun.16','Jul.12','Jul.13','Oct.5','Oct.27','Oct.28','Oct.29','Nov.19','Nov.20'});

Also, I need to double or triple the bar width, but when I set the bar widths to 2, the bars start ovelapping.

Any help would be appreciated.

Okay, here is the code for the figure:

Xday1=categorical({'Jan.3','Jan.4','Jan.12','Jan.13','Feb.23','Feb.24','Mar.1','Mar.2','Apr.6', ...
 'Jun.12','Jun.16','Jul.12','Jul.13','Oct.5','Oct.27','Oct.28','Oct.29','Nov.19','Nov.20'});
Xday1=reordercats(Xday1,{'Jan.3','Jan.4','Jan.12','Jan.13','Feb.23','Feb.24','Mar.1','Mar.2','Apr.6', ...
 'Jun.12','Jun.16','Jul.12','Jul.13','Oct.5','Oct.27','Oct.28','Oct.29','Nov.19','Nov.20'});

What are the variables used in the call to bar()? Provide the values for them as well.

Also, why are you dynamically naming variables?

Petr Michalek 2023-10-23

I am sorry, but you are asking for something completely different than I was asking. If you want to recreate my chart (sort of), just give to the variables some random numbers. I wanted to know how to align the Xtick Labels.

In theory...

labels = {'123', '1234', '12345678'};

ax = gca;

bar(ax, [3 5 7])

xticks(ax, 1:3)

xlim(ax, [0 4])

xticklabels(ax, labels)

xtickangle(ax, 90)

drawnow(); %needed or TickLabelChild will be empty

ax.XAxis.TickLabelChild.HorizontalAlignment = 'right'; %left center right

ax.XAxis.TickLabelChild.VerticalAlignment = 'bottom'; %top middle bottom

You can see in practice it does not work
