Change TooltipFormat

Hi, how do we change the TooltipFormat completely?  We don't want to display any of the default values as we are using the chart with different data types.  Thanks

Hi Alex, 

Greetings from Syncfusion. 

We can achieve your requirement of tooltip format by using the Format property in StockChartTooltipSettings.  We can add more information to the tooltip by using this property. However, we have created the simple blazor application to demonstrate the same and it can be downloaded from the below link. 



Code Snippet: 

<SfStockChart> 
    <StockChartCrosshairSettings Enable="true"></StockChartCrosshairSettings> 
    <StockChartTooltipSettings Enable="true" Format="<b>${point.Date} : ${point.Y}</b>" Fill="aqua"> 
    </StockChartTooltipSettings> 
    <StockChartSeriesCollection> 
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Column" XName="Date" YName="Y"></StockChartSeries> 
    </StockChartSeriesCollection> 
</SfStockChart>

Kindly, revert us if you have any concerns. 

Regards, 
Swetha

Hi, that hasn't worked, all that's done is added the additional values to the header.  We want to replace High/Low/Open/Close with out own text

Hi Alex, 

We are glad to announce that our v19.4.0.53 patch release is rolled out; we have added the fix for reported issue. You can use the latest Syncfusion.Blazor NuGet package version.  


We have added an events TooltipRender and SharedTooltipRender. Now you can customize the tooltip text based on your need. Please check with the below snippet and sample. 

<SfStockChart> 
<StockChartEvents  TooltipRender="@TooltipRender" SharedTooltipRender="@SharedTooltipRender"> 
</StockChartEvents> 
</SfStockChart> 
 
void SharedTooltipRender(SharedTooltipRenderEventArgs args) 
    { 
        //Customize text using args.Text 
    } 
    void TooltipRender(TooltipRenderEventArgs args) 
    { 
        args.Text = "Changed Text"; 
    } 


We thank you for your support and appreciate your patience in waiting for this release. Please get in touch with us if you would require any further assistance. 

Regards, 
Durga G

Hi,

How do we get the actual values (high, close, low, open, volume etc...) from the chart?  We just want to label these differently but we obviously need the data values.


Thanks,

Alex

Hi Alex, 

Greetings from Syncfusion. 

We can get the Open, Close, low, high values from the Point argument in TooltipRender Event. Please find the below capture screen for your reference.
