The following code is used to plot some random data on chart with DateTime as X.Axis Labels When I click on Zoom button and dragged the ZoomRectangle to some extent, and then When I click on print preview button , print preview window is producing 100+ pages. and the plot in print preview window is not matching with the chart plot. Following is the code written by me for this operation... public partial class Form1 : Form { double[] dblData = new double[300]; DateTime[] dblDateTime = new DateTime[300]; List<Array> lstArray = new List<Array>(); ListProvider lsListProvider = new ListProvider(); public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { cfxChart.Data.Clear(); PlotData(); cfxChart.Data.Series++; cfxChart.AxisX.LabelsFormat.CustomFormat = "hh:mm:ss\n dd/MM/yyyy"; cfxChart.AxisX.Step = 0.000001; cfxChart.AxisX.MinorStep = 0.000000001; lstArray.Add(dblData); lstArray.Add(dblDateTime); lsListProvider.List = lstArray; cfxChart.DataSource = lsListProvider; cfxChart.Series[0].MarkerShape = MarkerShape.None; cfxChart.UserZoom += new EventHandler(cfxChart_UserZoom); cfxChart.AxisY.Min = 70; cfxChart.AxisY.Max = 80; } void cfxChart_UserZoom(object sender, EventArgs e) { cfxChart.AxisY.ZoomOff(); cfxChart.AxisY.Min = 70; cfxChart.AxisY.Max = 80; } private void tsbtnRefresh_Click(object sender, EventArgs e) { } private void tsbtnZoomIn_Click(object sender, EventArgs e) { cfxChart.Zoom = true; } private void tsbtnZoomOut_Click(object sender, EventArgs e) { cfxChart.Zoom = false; } private void tsbtnPrintPreview_Click(object sender, EventArgs e) { cfxChart.Printer.PrintPreview(); } private void tsbtnPrint_Click(object sender, EventArgs e) { cfxChart.Printer.PrintDialog(true); } private void PlotData() { DateTime dtNow = DateTime .Now ; int i = 0; Random r = new Random (); while (i < 100) { dblData = r.Next(75,80); dtNow = dtNow.AddMilliseconds(10); dblDateTime = dtNow; i++; } while (i < 200) { dblData = 1E+108; dtNow = dtNow.AddMilliseconds(10); dblDateTime = dtNow; i++; } while (i < 300) { dblData = r.Next(75, 80); dtNow = dtNow.AddMilliseconds(10); dblDateTime = dtNow; i++; } } } Thanks & Regards Ravindranath
