Hi Julio,
Greetings from Syncfusion. We have analyzed your scenario and like to tell you that by default the intervals are calculated properly based on the given data for all types of axes. We suspect that you may set the range for the x-axis manually, which will lead to this behavior of x-axis labels like in the given screenshot. Please remove the manual range in the x-axis or set a proper interval that will resolve your issue. To know more about the axes and our charts, refer to the following help document,
You can also use labelIntersectAction property to avoid overlapping of axis labels and to know more refer to the help document.
Please revert us if you need further assistance.
Thanks,
Dharanitharan. P
