Print & Print Preview regd

[Ravindra]

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++;

  }

  }

  }
