MDS Posted January 16, 2008 Report Share Posted January 16, 2008 When I perform the following, I get an error "OverflowException was unhandled." Any idea why? If I comment out the line series1.YAxis = YAxis.Secondary;, then I don't get the error. OracleConnection connection = new OracleConnection(connectionString); string sql = "select month_num, numvalue1, numvalue2 from mytable";using (connection) { OracleCommand command = new OracleCommand(sql, connection); OracleDataAdapter dataAdapter = new OracleDataAdapter(command);dataAdapter.Fill(dataset, "Table0"); } chart1.DataSourceSettings.DataType[0] = DataType.Label; chart1.DataSourceSettings.DataType[1] = DataType.Value;chart1.DataSourceSettings.DataType[2] = DataType.Value; chart1.DataSource = dataset.Tables[0]; SeriesAttributes series0 = chart1.Series[0]; SeriesAttributes series1 = chart1.Series[1];series0.Gallery = Gallery.Bar; series1.Gallery = Gallery.Lines;series1.YAxis = YAxis.Secondary; chart1.Refresh(); Link to comment Share on other sites More sharing options...
Frank Posted January 17, 2008 Report Share Posted January 17, 2008 The problem here is that your secondary Y-Axis remains "uninitialized", that is whitout a scale. The best way to avoid this is to move your line: series1.YAxis = YAxis.Secondary; To BEFORE the databindong occurs (before assigning chart.DataSource), this way the secondary Y-Axis scale will be adjusted with the data comming in.
