Hi, I'm newbie to using stock chart,

I made three different charts.

first and second chart loads data when initialize the page and those

"StockChartPrimaryXAxis" is mentioned as

<StockChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.DateTimeCategory">

It works perfect but not the third one.

third one calls the data with null at initialization.

When I choose the selection with dropdownbox,

StockChartSeries DataSource="@stockhistorylist" stockhistorylist will be called and call refresh() method.

I tried,

1) call valuetype at the first,

<StockChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.DateTimeCategory">

then, I got this error,

warn: Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer[100]

Unhandled exception rendering component: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

2) I tried using base type for StockChartPrimaryXAxis by

<StockChartPrimaryXAxis @ref=@mainx ValueType="@mainchartXAxis">

StockChartPrimaryXAxis mainx = new();

Syncfusion.Blazor.Charts.ValueType mainchartXAxis = new();

and when stockhistorylist.count() == 0, I changed mainchartXAxis to Syncfusion.Blazor.Charts.ValueType.DateTime

and when stockhistorylist.count() > 0 , I changed mainchartXAxis to Syncfusion.Blazor.Charts.ValueType.DateTimeCategory

then, I've got this error,

warn: Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer[100]
