c# - 在WinForms中更新雷达图

我有以下UI，其中Radar Chart中的值是通过某些TrackBar值的算术平均值计算得出的。 “ Player”对象获取这些值，计算平均值并将其返回到Radar Chart数据系列。

我想做的是，当我在TrackBar中更改值时，Chart实时更改其值。当我更改值时，它会重新计算平均值，然后更改图表形状。



这是我的代码：

public AddPlayerForm()
    {
        InitializeComponent();
        Load += this.AddPlayerForm_Load;//reloads the chart component every continuously
        LoadComboBoxes();
        MetroFramework.Controls.MetroTrackBar[] trackBars = new MetroFramework.Controls.MetroTrackBar[20];
    }

    //loads the Chart Content
    private void AddPlayerForm_Load(object sender, EventArgs e)
    {
        /*I tried to clear the current chart to recalculate and redraw the chart in every cycle
        but its not working this way*/
        chart1.Series.Clear();//clear the current chart
        new_player.SetPlayerStats(  //get values from TrackBars
         mtTrackBarAttack.Value,
         mtTrackBarBallControl.Value,
         .
         .//all trackBar.Values
         .
         mtInjuryResistenceTB.Value,
         1,
         "Messi");

        //recalculate the arithimetic mean and returns as a tag to the chart
        //Ex: {"Agility",60.4}
        Dictionary<string, float> tags = new_player.MeanStats();//Player method that calculates the mean and returns a dictionary <String, float>
        //creates a new series of data
        chart1.Series.Add("s1");
        chart1.Series["s1"].ChartType = SeriesChartType.Radar;


        foreach (string tagname in tags.Keys)
        {
            //for each set of data, plots the name and its value in the Chart
            chart1.Series["s1"].Points.AddXY(tagname, tags[tagname]);

        }


    }

我正在尝试清除旧图表并重绘新图表，但这种方式无法正常工作。

我从未使用过Winforms-Charttool，但您是否已经尝试过仅调用chart1-Object的刷新？
