+## DateTimeCategoryAxis
+
+The [DateTimeCategoryAxis]() is a specialized type of axis primarily used with financial series. Similar to the [CategoryAxis](https://help.syncfusion.com/cr/maui-toolkit/Syncfusion.Maui.Toolkit.Charts.CategoryAxis.html), all data points are plotted with equal spacing, eliminating gaps for missing dates. The intervals and ranges for this axis are calculated similarly to the [DateTimeAxis](https://help.syncfusion.com/cr/maui-toolkit/Syncfusion.Maui.Toolkit.Charts.DateTimeAxis.html). There are no visual gaps between points, even if the difference between two points exceeds a year.

+
+### Interval
+
+In [DateTimeCategoryAxis](), intervals can be customized by using the Interval and IntervalType properties, similar to [DateTimeAxis](https://help.syncfusion.com/cr/maui-toolkit/Syncfusion.Maui.Toolkit.Charts.DateTimeAxis.html). For example, setting [Interval]() as 3 and [IntervalType]() as [Months]() will consider 3 months as interval.

 ## Logarithmic Axis
 
 The [LogarithmicAxis](https://help.syncfusion.com/cr/maui-toolkit/Syncfusion.Maui.Toolkit.Charts.LogarithmicAxis.html) uses a logarithmic scale, and it is very useful in visualizing data when the given data range has a big difference. It can be used either on the x-axis or the chart's y-axis.
