Lists values that specify the chart’s axis types.
Namespace : DevExpress.Blazor
Assembly : DevExpress.Blazor.v25.2.dll
NuGet Package : DevExpress.Blazor
public enum ChartAxisType
| Name | Description |
|---|---|
Auto |
Automatically detects the series’s data type and uses it to render the axis. For integer and float data types, displays numeric arguments/values divided by ticks. For other data types, displays discrete arguments/values that correspond to chart points.
|
| Continuous |
The axis uses a continuous scale to display numeric and date-time values.
|
| Discrete |
Displays discrete arguments/values that correspond to chart points.
|
| Logarithmic |
Displays numeric arguments/values that grow exponentially. Each axis argument/value equals the specified logarithm base raised to a power (for instance, 10⁻², 10⁻¹, 10⁰, 10¹, 10², etc.).
|
The following properties accept/return ChartAxisType values:
The following example displays argument axes of the Discrete type, and value axes of Continuous and Logarithmic types, respectively. The LogarithmBase property for the second chart is set to 2.
