100 Percent Stacked Bar Chart won't show tooltip if value is 0

[Priyansh]

Hi I found strange issue for not displaying tooltip if we found Y axis value is 0. In my example, I have Y1Series and Y2Series .. for Y1Series I have 0 value and Y2Series got 100 , so in tooltip it's shows Y2Series with tooltip information , but not Y1Series. 

In example below Genotyped is Y1Series and Total is Y2Series , I always get tooltip for Total (Y2series) , but not Genotype(Y1Series). Note: Y1Series has >0 values , tooltip showing Y1Series data. It has issue with 0 value only

Note: tooltip showing for Y1Series(Genotyped) when we have value, in this case 16% for Cows does display value

I added Custom tooltip

Hi Priyansh,

Greetings from Syncfusion.

We suggest you to enable shared tooltip for chart to view the zero value in tooltip. By default, for normal tooltip while hovering over the column rectangle tooltip will be displayed, for zero value rectangle won’t be rendered so there is no option to display tooltip. When shared is enabled, closest point will be displayed in tooltip. We have prepared sample based on your requirement.

<SfChart>

   <ChartTooltipSettings Shared=true Enable="true"></ChartTooltipSettings>

</SfChart>

Kindly revert us if you have any concerns.

Hi Priyansh,

We are glad to announce that our v25.2.4 patch release is rolled out; we have added the fix for reported issue. You can use the latest Syncfusion.Blazor.Charts NuGet package.

Root Cause:

In the tooltip template, if the YValue is set to 0, then the tooltip's YValue is set to an empty string, making it not visible in the tooltip.

Fix:

When YValue is set to 0, then specified the tooltip's YValue to 0 instead of an empty string, making it visible in the tooltip.

NuGet Package : https://www.nuget.org/packages/Syncfusion.Blazor.Charts/
