How can I get rid of the gap on the x-axis?

Dear all,

I have the following code which results in the shown graph. However, I would like to make the graph prettier by avoiding the gap at the end of the x-axis as well as bigger spacing between the x-ticks and x-labels. Help is much appreciated :-)

            app.UIAxesThUeberschuss.XLimMode = 'auto';
            app.UIAxesThUeberschuss.YLimMode = 'auto';
            app.UIAxesThUeberschuss.XTick = (0:hournum:projectlengthhour); % needed to show years instead of hours
            app.UIAxesThUeberschuss.XTickLabel = (0:projectlength); % needed to show years instead of hours       
            zoom(app.UIAxesThUeberschuss,'on');
            plot(app.UIAxesThUeberschuss,1:projectlengthhour,P_ueber.th); 

Info:

• hournum = 8760
• projectlength = 30
• projectlengthhour = 262800 (=hournum * projectlength)
• P_ueber.th is a 262800x1 vector

you can use xlim to get rid of the gap.

Consider rotating the tick font 90 degrees. https://www.mathworks.com/help/matlab/ref/xtickangle.html

hello Maria

for the first point , try to switch from 'auto' to 'manual' and specify the range

Current limits mode, returned as one of these values:

• 'auto' — Automatically determine the limits.
• 'manual' — Use manually specified limits that do not update to reflect changes in the data.

For the second point , you have to increase the x spacing

for the time being I assume from the plot x axis, that hournum = 1

try now with an increased value , for example hournum = 5 , now you should see only 0,5,10,... values , which makes the whole axis more readable

you have also to update the XTickLabel with the new spacing :

app.UIAxesThUeberschuss.XTickLabel = (0:hournum:projectlength);

Hello Mathieu and Walter,

switching to manual would not work as the projectlength and projecthour can be both adusted in the app.

[Walter Roberson]

Manual is configured automatically if you use xlim(). You would xlim() passing in the min() and max() of the x data, which often would correspond to the first and last x values.

Nice, I tried

app.UIAxesPV_ungeordnet.XLim = [0 projectlengthhour];

and it worked. Thanks!

How about

axis tight

would that work?
