On a bar chart, what happens to the x-tick labels if the text becomes long?
When x-tick label strings become too long, you will not get any error messages. However, the label text will start to overlap with the other label text, which can make them hard to read.
To prevent the issue of labels overlapping, you might utilize the rotation parameter, which will rotate the text for each label. By rotating the text, the text is no longer stuck stretching out horizontally but will stretch out on an angle, which will prevent overlap with the other labels.
Another way to prevent the issue of overlap is by avoiding it entirely. This can be done by choosing label text lengths that are not too long. You might do this by abbreviating terms.
Having label text that is easy to read is important so that other people will also be able to read and understand the information displayed on your graphs.
