chart tooltip axis title

[scorp]

Can we have a tooltip show up on mouse hover on the chart's Axis Title?

Hello,

Yes, it can be done by creating a style targeting the AxisTitle and using the ToolTipService.ToolTip property to set the text you would like. See the code below as an example:

<UserControl.Resources>
<Style x:Key="chartTitleStyle" TargetType="telerik:AxisTitle">
    <Setter Property="ToolTipService.ToolTip" Value="My axis tooltip text here" />
</Style>

and then use the TitleStyle property of the AxisX to apply the style, like this:

radChart.DefaultView.ChartArea.AxisX.Title = "Axis Title";
radChart.DefaultView.ChartArea.AxisX.AxisStyles.TitleStyle = this.Resources["chartTitleStyle"] as Style;

Using the above approach will show a tooltop when user hovers the axis title.

Hope this helps.

Thanks that worked. Is there a way to increase the font size of the tooltip?

Hi,

You can increase the size of the tooltip's text by using RadToolTipService instead of ToolTipService. Then using RadToolTipService.ToolTipContentTemplate property you can create your own template like this:

<UserControl.Resources>
        <Style x:Key="chartTitleStyle" TargetType="telerik:AxisTitle">
            <Setter Property="telerik:RadToolTipService.ToolTipContentTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <Grid MaxWidth="200">
                            <Rectangle Margin="0" RadiusX="2" RadiusY="2" Fill="Brown" />
                            <Rectangle Margin="2" RadiusX="2" RadiusY="2" Fill="Beige" />
                            <TextBlock Margin="5" TextWrapping="Wrap" FontFamily="Comic Sans MS" Text="My Tooltip text"/>
                        </Grid>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
            <Setter Property="telerik:RadToolTipService.ToolTipContent" Value="TEST" />
        </Style>
    </UserControl.Resources>

Hope this helps.
