Guilherme,

Axis labels will be shown at every interval – which is auto-calculated based on parameters like axis minimum, axis maximum, etc. You can change interval to show all labels. In case of date-time axis, set intervalType along with interval according to your requirements.

If you are still facing any issue, kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into your code, understand the use-case better and help you out.
