Create an array with chart points

Question

Hello, I'm creating a graph that records temperature values recorded over time, so that the X axis records the hours and the Y axis records the temperature values.
What I need is to save the temperature values registered in an array or a list, that is, create a list of temperatures.

How do I do this?

You can use Datatable as the data source of the chart, and then use Timer to call the method to get the temperature.

A simple example:

        private Timer Timer;  
        private DataTable Tems;  
        private void Form1_Load(object sender, EventArgs e)  
        {  
            chart1.Series[0].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line;  
            chart1.Series[0].Color = Color.Red;  
            Tems = new DataTable();  
            Tems.Columns.Add("Time",typeof(int));  
            Tems.Columns.Add("temperature",typeof(double));  
            chart1.Series[0].XValueMember = "Time";  
            chart1.Series[0].YValueMembers = "temperature";  
            chart1.DataSource = Tems;  
            chart1.DataBind();  
  
            Timer = new Timer();  
            Timer.Interval = 5 * 1000;  
            Timer.Tick += Timer_Tick;  
            Timer.Start();  
        }  
  
        private void Timer_Tick(object sender, EventArgs e)  
        {  
            Tems.Rows.Add(h++, 36.5 + n++);  
            chart1.DataBind();  
        }  
       
        double n = 1.2;  
        int h = 1;  
        private void button1_Click(object sender, EventArgs e)  
        {  
            Timer.Stop();  
        }
