Hello,

I'm having problems exporting a chart, because the chart has only a serie but with 122,652 values. I get this error:

Code: Select all

Property accessor 'DataSource' on object 'Steema.TeeChart.Styles.Line' threw the following exception:'Exception of type 'System.OutOfMemoryException' was thrown.'

I tried running:

Code: Select all

          chart.Export.Template.IncludeData = false;
            chart.Export.Template.Save(path);

Because I don't need to save the data, but I think the includeData= false sentence is not running because it spend quite lot time trying to save an then throws the same error...

I tried deleting the data of the serie before save it, but then chart deletes the data to the user and to get it from the database spends too time to get it again transparently.

Do you know any way to solve it?

Thanks

Hello wakeup,

I have tried to reproduce your problem, and here it doesn't appear using next code and changing property chart1.Export.Tamplate.IncludeData to true or false:

Code: Select all

        public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }

        private Steema.TeeChart.TChart chart1, chart2;
        private Steema.TeeChart.Styles.Line line1;
        private void InitializeChart()
        {
           chart1 = new Steema.TeeChart.TChart();
           chart2 = new Steema.TeeChart.TChart();
           this.Controls.Add(chart1);
           this.chart1.Location = new System.Drawing.Point(-3, 141);
           this.chart1.Size = new System.Drawing.Size(475, 293);
           this.chart1.TabIndex = 0;
           this.Controls.Add(chart2);
           this.chart2.Location = new System.Drawing.Point(493, 141);
           this.chart2.Size = new System.Drawing.Size(453, 293);
           this.chart2.TabIndex = 1;
           line1= new Steema.TeeChart.Styles.Line(chart1.Chart);
           line1.Add(1, 122);
           line1.Add(2, 652);
           chart1.Export.Template.IncludeData = false;//true;
           chart1.Export.Template.Save(@"C://TeeChart1.ten");
           chart2.Import.Template.Load(@"C://TeeChart1.ten");
        }

Please, check if previous code works as you want. If it doesn't work for you, please, modify code because we can reproduce your problem here.

Thanks,

I tested it better and your are right it doesn't save the data, but it save something big.

I can't reproduce the problem with your example, but I have attached in this post my chart saved without data, but as you can be its size is 3MB!

What is it saving?

Thanks!
