Stockchart zooming programmatically doesn't work

Hello,

How to perform zooming programmatically in Blazor Charts?

I tried to use Period Selector and I customize it but is it possible to hide the Indicators dropdown in Period Selector toolbar ?

Your requirement can be achieved by specifying empty list for indicators in stock chart. We have prepared sample based on your requirement. Please check with below snippet and sample.

<SfStockChart IndicatorType="@Indicators"></SfStockChart>

@code {

    List<TechnicalIndicators> Indicators = new List<TechnicalIndicators>() { };

}

Praveen,

Thank you for your patience. We have addressed the reported issue at the sample level. To avoid unnecessary re-renderings in the stock chart, we have prevented the StateHasChanged method from being triggered to re-render the chart. Instead, we recommend using the UpdateStockChart method to refresh the stock chart when dynamically changing the zoom factor and zoom position. For your reference, we have attached the updated sample.

public void ZoomIn()

{

    SetZoomFactor -= 0.1;

    stockchart.UpdateStockChart();

}

public void ZoomOut()

{

    SetZoomFactor += 0.1;

    stockchart.UpdateStockChart();

}

public void ResetZoom()

{

    SetZoomFactor = 1;

    stockchart.UpdateStockChart();

}
