LineChart with series help
posted

Ok, I am starting to get frustrated here. Not sure what I am doing wrong. I have a UltraChart set to LineChart. I create a NumericSeries and call UltraChart.Series.Add(mySeries). Every time a certain event is fired I add a NumericDataPoint to mySeries. For some reason, it never graphs anything. What am I missing? The code is below:

mySeries = new NumericSeries();mySeries.Visible = true;

mySeries.Label = _watch[0].CarNumber;

watchRunChart.Series.Add(mySeries);

In the event:

mySeries.Points.Add( new NumericDataPoint(Math.Round(lap.LapTime.TotalSeconds), tod.ToString(), false));

I am sure I am missing something simple! Any help would be much appreciated. By the way this is v7.3 and ultimately I will need to add 6 seperate series to this chart. Is that possible? Thanks!

    In what event are you adding the new points?

    I tried the following in button click and had no issues.  You may run into issues if you are trying to do the same not on the UI thread.  Also, I did this in 8.2 but it should be the same in 7.3.

    private void button1_Click(object sender, EventArgs e)

    {

    for (int x = 0; x < 5; x++)

    {

    ((    NumericSeries)this.ultraChart1.Series[x]).Points.Add(new NumericDataPoint(System.DateTime.Now.Second-x, x.ToString(), false));

    }

    }

    private void Form1_Load(object sender, EventArgs e)

    {

    NumericSeries ns;for(int x =0;x<5;x++)

    {

    ns = new NumericSeries();

    this.ultraChart1.Series.Add(ns);

    }

     

    }
