Configures the chart value axis.
A chart integrated in the RangeSelector differs from a stand-alone Chart widget in the axes. The argument axis of the integrated chart is replaced by the RangeSelector scale. The value axis loses its visual representation along with ticks, labels, grids and strips, retaining only those properties that shape it.
Indicates whether or not the chart's value axis must be inverted.
When inverted, the minimum value of the value axis is placed at the top and the values increase as you approach the bottom of the chart, so that the maximum value appears at the bottom. As a result, the chart series are inverted.
Specifies the value to be raised to a power when generating ticks for a logarithmic value axis.
Although, the value axis displaying series values is invisible in the RangeSelector, it is still divided by ticks. By default, the ticks on the value axis of a logarithmic type are generated on a base of 10, i.e., 0.1, 1, 10, 100, 1000, etc. But you can specify a base you require using the logarithmBase option. For example, if you set this option to 5, the following ticks will be generated: 0.5, 5, 25, 125, 625, etc.
Specifies the maximum value of the chart's value axis.
Specifies the minimum value of the chart's value axis.
Specifies the type of the value axis.
The 'continuous' type is set when numeric or date-time values are specified in the series data source. The continuous axis is divided into intervals automatically.
The 'logarithmic' type can be set when numeric values are specified in the series data source. The logarithmic axis is useful when you visualize a dataset of rapidly-growing values. Each axis tick represents a particular value that is raised to the next power in turn. This particular value is specified by the logarithmBase option. For example, if you set this option to 5, the following ticks will be generated: 50, 51, 52, 53, etc.
In addition, you can use the scale of a logarithmic type to display series arguments.
RangeSelectorChartAxisScaleType enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values:
Specifies the desired type of axis values.
The type of the axis values is determined based on the type of the values specified in the corresponding data source field of the chart series. If numeric values are specified in the series data source, the axis values will also be of the numeric type. The same logic is used when string or date-time values are specified in the data source.
In some scenarios, you may need the type of values specified in the data source to be converted to another type. In this instance, specify the desired type for the axis values using the valueType property.
ChartDataType enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values:
