C# desktop chart draw complete takes long time
0
I am creating C# chart using button click.
void myButton_Click(object sender, RoutedEventArgs e)
{
DrawChart();
MessageBox.Show("Draw complated");
}
private void DrawChart()
{
for (int i = 0; i < 30000; i++)
{
Series series = this.chart1.Series.Add(seriesArray[i]);
series.Points.Add(pointsArray[i]);
}
}
I have about 30000 points. So when I click the button, the message box shows immediately, but the graphic is drawn after 5-10 seconds. The users gets the message box before but there is no chart on chart area about 10 seconds.
How can I solve this problem?

use less points or maybe cashe the chart result if that is possible

Data is 30000, so I should use data count. Is there any property of chart to use 1000 points of these 30000 points?

I mean to add less points to the chart if the speed is the problem. For example, adding every 30th point by replacingi++withi += 30

Why do you add so many Series??? That is not what series is made for! 30k points is even a lot but series??? Why would you use more than one series??

Try using Chart event.
public partial class Form1 : Form
{
private int _pointsCount;
public Form1()
{
InitializeComponent();
}
private void Draw()
{
_pointsCount = 300000;
var range = Enumerable.Range(0, _pointsCount);
Series series = new Series();
foreach (var i in range)
{
series.Points.Add(new DataPoint(0, i));
}
chart1.PostPaint += OnDrawingFinished;
chart1.Series.Add(series);
}
private void OnDrawingFinished(object sender, ChartPaintEventArgs e)
{
var chart = (Chart)sender;
var points = chart.Series.SelectMany(x => x.Points).Count();
if (points < _pointsCount) return;
MessageBox.Show("Done!");
chart1.PostPaint -= OnDrawingFinished;
}
private void button1_Click(object sender, EventArgs e)
{
Draw();
}
}
Wokrs here for me for first try. Its not so elegant way but still works.

Preparing a series before adding it to th chart is probably a good idea. But the main difference is that you inly create one series, not 30k. Also: What do you mean byChart event?
