Line chart gets muddled up when using multiple series

[Isaac Mane]

I have a line chart that uses multiple series. It works well enough on the initial load but when filters are applied, it gets muddled up, and when the page is zoomed in or out, it goes back to normal.

Please look at this gif.

This is the chart markup

and this is how the chart is loaded

I use .NET 5 and Syncfusion 19.4.0.56

Hi Isaac,

We have ensured your reported scenario in .NET 5 with specified NuGet version 19.4.0.56. We suggest you to call the chart RefreshAsync method after changing the chart series datasource using dropdown list. We have prepared sample as per your attached GIF. Please check with below sample and video.

public void ChangeData(ChangeEventArgs<string, DropDownData> args)

    {

        if (args.Value.ToString() == "Last 7 Days")

        {

            this.ChartPoints = new List<DateTimeData>

            {

                new DateTimeData { Day = new DateTime(2023, 1, 16), DEU_Temp = 35, JPN_Temp = 31 },

                //…

           };

        }

        else if (args.Value.ToString() == "Last 2 Weeks")

        {

            this.ChartPoints = new List<DateTimeData>

            {

                new DateTimeData { Day = new DateTime(2023, 1, 09), DEU_Temp = 25, JPN_Temp = 21 },

                //…

           };

        }

        chartObj.RefreshAsync(false);

 

    }
