LineChart displays only 15 colums of series
posted

Hi,

I'm using WinChart 9.1 and want to display a NumericTimeSeries with the date-value on the x-axis and the amount on y-axis. Everything is fine, but after 15 columns the chart ends on the x-axis and no bigger values are displayed.

Thanks a lot,

Alex

    The chart shouldn't normally have any trouble displaying a large amount of data. Perhaps something is preventing it from doing so. Here's a few things you can check:

    if you have more than one series, make sure that each series has an equal amount of points. Otherwise, you have to use a composite chart.

    Make sure that you're not setting a range on the X axis. Check chart.Axis.X.RangeMin/RangeMax/RangeType properties

    As a sanity check try this code and see if it works:

    DataTable dt = new DataTable();
    dt.Columns.Add("date", typeof(DateTime));
    dt.Columns.Add("value", typeof(double));
    dt.Columns.Add("label", typeof(string));

    for (int i = 0; i < 50; i++)
    {
       dt.Rows.Add(DateTime.Now.AddDays(i), i, "label " + i);
    }

    NumericTimeSeries series = new NumericTimeSeries();
    series.Data.DataSource = dt;
    series.Data.TimeValueColumn = "date";
    series.Data.LabelColumn = "label";
    series.Data.ValueColumn = "value";
    series.DataBind();

    ultraChart1.ChartType = ChartType.LineChart;
    ultraChart1.LineChart.TreatDateTimeAsString = false;
    ultraChart1.Series.Add(series);
