Hi,
I'm experimenting with the tooltips in the sparkline control and I think I found a bug.
If you look at the demo page on https://blazor.syncfusion.com/demos/sparkline/axis-types?theme=fluent, and hover over the first demo [Mean Working Hours for a Month (DateTime Axis)], the tooltips always show the 1st of January 1970, even if the dates in the code are of 2018. I see the same behaviour in my own code.
Also, if you use the example of https://blazor.syncfusion.com/documentation/sparkline/axis-customization#change-the-value-type-of-the-sparkline-chart, and the following code:
<SfSparkline DataSource="@ExpenditureReport" TValue="ExpenditureDetails" XName="Year" YName="Expense" Type="SparklineType.Column" ValueType="SparklineValueType.Numeric" Height="250px" Width="450px">
<SparklineTooltipSettings TValue="ExpenditureDetails" Visible="true" Format="${Year}: ${Expense}" Fill="lightgrey">
</SparklineTooltipSettings>
</SfSparkline>
The tooltip does not show the Year value but the index.
Then a question: how does one format the DateTime value in the tooltip? Show only the time, for instance?
EDIT: if you edit the question, the formatted code apparently disappears. Added it again.
Just wanted to let you know.
Regards,
Alex
