Property Value

Type	Description
DevExpress.Web.Bootstrap.VisualRangeSettings	Specifies the limits of the displayed axis range.

Remarks

The VisualRangeSettings property sets axis limits to focus the widget on a specific chart segment.

Use one of the following properties to define the visual range of an axis:

• StartValue/EndValue Property

• Length Property

• MinLength Property

StartValue and EndValue

Specify the StartValue and EndValue properties:

• StartValue - defines the range’s minimum value.

• EndValue - defines the range’s maximum value.

A numeric axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <NumericAxis StartValue="2000" EndValue="5000" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

A string axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <StringAxis StartValue="Russia" EndValue="India" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

A date axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <DateAxis StartValue="3/9/2017" EndValue="3/23/2017"/>
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

Length

The Length property defines the length of the displayed axis range. The axis ends at the last data value.

A numeric axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <NumericAxis Length="1000" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

A string axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <StringAxis Length="2" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

A date axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <DateAxis Length-Months="3" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>

MinLength

The MinLength property defines the minimum visual range of the axis when you zoom it.

A numeric axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <NumericAxis MinLength="1000" />
      </VisualRangeSettings>
  </ArgumentAxis>
  <SettingsZoomAndPan AllowMouseWheel="true" ArgumentAxis="Zoom">
</dx:BootstrapChart>

A string axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <StringAxis MinLength="2" />
      </VisualRangeSettings>
  </ArgumentAxis>
  <SettingsZoomAndPan AllowMouseWheel="true" ArgumentAxis="Zoom">
</dx:BootstrapChart>

A date axis:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <DateAxis MinLength-Months="5"></DateAxis>
      </VisualRangeSettings>
  </ArgumentAxis>
  <SettingsZoomAndPan AllowMouseWheel="true" ArgumentAxis="Zoom">
</dx:BootstrapChart>

You can combine the techniques described above, such as the StartValue and Length properties:

ASPX

<dx:BootstrapChart ID="Chart" runat="server" ...>
  <!--...-->
  <ArgumentAxis>
      <VisualRangeSettings>
          <NumericAxis StartValue="3200" Length="1300" />
      </VisualRangeSettings>
  </ArgumentAxis>
</dx:BootstrapChart>
