更改DevExpress控件中的数值格式

我想更改WebChartControl系列模板中点标签上的数值格式。例如，我在点上的值是“20.1003435434”，我会将其设置为“20.10”。我试图设置numerioptions format=“Currency”和Precision=“0”。但我不可能成功。这是我的密码：

<dxchartsui:WebChartControl ID="WebChartControl" runat="server" DataSourceID="ASPxPivotGrid" Height="300px" SeriesDataMember="Series" Width="900px" Visible="False">
        <diagramserializable>

                    <numericoptions format="General" />
                </axisx>
                <axisy title-text="Değer" visibleinpanesserializable="-1">
                    <range sidemarginsenabled="True" />
                    <numericoptions  Format="Currency" Precision="0" />
                </axisy>
