C # Chart Controls real-time dynamic display of data

Here is a complete example of the simplest real-time display data,

This article refers to the use of MSChart real-time dynamic display line chart, thank the original author's share.

Platform: Vs2013,c#windows program.

1. First, add the chart control to the window.

2, set chart-series main T attribute:

2.1 isxvalueindexed = true;

2.2 Xvaluetype = time;

3. Write initialization function:

private void Initchart ()
        {
            DateTime time = DateTime.Now;
            Charttimer.interval = 1000;
            Charttimer.tick + = Charttimer_tick;
            Chartdemo.doubleclick + = Chartdemo_doubleclick;

            Series Series = chartdemo.series[0];
            Series. ChartType = Seriescharttype.spline;

            Chartdemo.chartareas[0]. AxisX.LabelStyle.Format = "HH:mm:ss";
            Chartdemo.chartareas[0]. AxisX.ScaleView.Size = 5;
            Chartdemo.chartareas[0]. AxisX.ScrollBar.IsPositionedInside = true;
            Chartdemo.chartareas[0]. AxisX.ScrollBar.Enabled = true;

            Charttimer.start ();

        }

4. Write Timer event:

void Charttimer_tick (object sender, EventArgs e)
        {
            Random ra = new Random ();
            Series Series = chartdemo.series[0];
            Series. POINTS.ADDXY (DateTime.Now, RA. Next (1));
            Chartdemo.chartareas[0]. AxisX.ScaleView.Position = series. points.count-5;
            throw new NotImplementedException ();
        }

5, write chart double-click event. (Because the slider can be hidden, hidden after not knowing how to recover, so I wrote this double-click event to restore the slider)

void Chartdemo_doubleclick (object sender, EventArgs e)
        {
            chartdemo.chartareas[0]. AxisX.ScaleView.Size = 5;
            Chartdemo.chartareas[0]. AxisX.ScrollBar.IsPositionedInside = true;
            Chartdemo.chartareas[0]. AxisX.ScrollBar.Enabled = true;
            throw new NotImplementedException ();
        }

6, the complete code is as follows:

Using System;
Using System.Collections.Generic;
Using System.ComponentModel;
Using System.Data;
Using System.Drawing;
Using System.Linq;
Using System.Text;
Using System.Threading.Tasks;
Using System.Windows.Forms; Using System.Windows.Forms.DataVisualization.Charting;
            You need to add a namespace namespace Chartrealtimeshow {public partial class Form1:form {public Form1 () {
            InitializeComponent ();
        Initchart ();

        } System.Windows.Forms.Timer Charttimer = new System.Windows.Forms.Timer ();
            private void Initchart () {DateTime time = DateTime.Now;
            Charttimer.interval = 1000;
            Charttimer.tick + = Charttimer_tick;

            Chartdemo.doubleclick + = Chartdemo_doubleclick;
            Series Series = chartdemo.series[0]; Series.

            ChartType = Seriescharttype.spline; Chartdemo.chartareas[0].
            AxisX.LabelStyle.Format = "HH:mm:ss"; Chartdemo.chartareas[0]. Axisx.scAleview.size = 5; Chartdemo.chartareas[0].
            AxisX.ScrollBar.IsPositionedInside = true; Chartdemo.chartareas[0].

            AxisX.ScrollBar.Enabled = true;

        Charttimer.start (); } void Chartdemo_doubleclick (object sender, EventArgs e) {chartdemo.chartareas[0].
            AxisX.ScaleView.Size = 5; Chartdemo.chartareas[0].
            AxisX.ScrollBar.IsPositionedInside = true; Chartdemo.chartareas[0].
            AxisX.ScrollBar.Enabled = true;
        throw new NotImplementedException ();
            } void Charttimer_tick (object sender, EventArgs e) {Random RA = new Random ();
            Series Series = chartdemo.series[0]; Series. POINTS.ADDXY (DateTime.Now, RA.
            Next (1, 10)); Chartdemo.chartareas[0]. AxisX.ScaleView.Position = series.
            points.count-5;
        throw new NotImplementedException ();
 }

    }
}
