    @Majeed Purseyedmahdi , about your second question, you could refer to the following code to use combobox to load different types in chart.

    private void Form1_Load(object sender, EventArgs e)  
            {  
                fillChart();  
                var resourceStream = typeof(System.Windows.Forms.DataVisualization.Charting.Chart)  
                .Assembly.GetManifestResourceStream("System.Windows.Forms.DataVisualization.Charting.Design.resources");  
                using (System.Resources.ResourceReader resReader = new ResourceReader(resourceStream))  
                {  
                    var dictEnumerator = resReader.GetEnumerator();  
                    while (dictEnumerator.MoveNext())  
                    {  
                        var ent = dictEnumerator.Entry;  
                         
                        comboBox1.Items.Add(ent.Key);  
                    }  
                }  
            }  
      
            private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)  
            {  
                Console.WriteLine(comboBox1.SelectedItem.ToString().Replace("ChartType",""));  
                string a = comboBox1.SelectedItem.ToString().Replace("ChartType", "");  
                SeriesChartType type = (SeriesChartType)Enum.Parse(typeof(SeriesChartType), a);  
                chart1.Series[0].ChartType = type;  
            }  
    

    Result:
