title: Why does auto Zoom/Scroll not work for my Chart?
body: <p>to make it short I checked on the <strong>"WinFormsChartSamples"</strong> provided by Microsoft. What I wanted to know is how to enable zooming and scrolling for Chartcontrols. The example which is shown there is pretty short.</p>
  
  <pre><code>using System.Windows.Forms.DataVisualization.Charting;
  ...
  
  // Set automatic zooming
  chart1.ChartAreas["Default"].AxisX.ScaleView.Zoomable = true;
  chart1.ChartAreas["Default"].AxisY.ScaleView.Zoomable = true;
  
  // Set automatic scrolling 
  chart1.ChartAreas["Default"].CursorX.AutoScroll = true;
  chart1.ChartAreas["Default"].CursorY.AutoScroll = true;
  
  ...
  </code></pre>
  
  <p>I tried this and nothing happened, no zooming and no scrolling. I tried two things:</p>
  
  <ol>
  <li><p>In Form1.Designer.cs I added that information to the chart.</p>
  
  <pre><code>    chartArea1.Name = "ChartArea1";
      chartArea1.CursorX.AutoScroll = true;
      chartArea1.CursorY.AutoScroll = true;
  
      chartArea1.AxisX.ScaleView.Zoomable = true;
      chartArea1.AxisY.ScaleView.Zoomable = true;
  
      this.chart1.ChartAreas.Add(chartArea1);
      this.chart1.Cursor = System.Windows.Forms.Cursors.Cross;
      legend1.Name = "Legend1";
      this.chart1.Legends.Add(legend1);
      this.chart1.Location = new System.Drawing.Point(297, 62);
      this.chart1.Name = "chart1";
      series1.ChartArea = "ChartArea1";
      series1.Legend = "Legend1";
      series1.Name = "Series1";
      this.chart1.Series.Add(series1);
      this.chart1.Size = new System.Drawing.Size(963, 668);
      this.chart1.TabIndex = 6;
      this.chart1.Text = "chart1";
  </code></pre></li>
  <li><p>I tried to add it directly into the constructor in Form1.cs.</p></li>
  </ol>
  
  <p>Perhaps it is important to mention that I am using OpenFileDialog in order to add data to the series:</p>
  
  <pre><code>private void openToolStripMenuItem_Click(object sender, EventArgs e)
          {
  
              Stream fileStream = null;
              OpenFileDialog fDialog = new OpenFileDialog();
              fDialog.Title = "Open File..";
              //First the description of the file separated by "|"
              fDialog.Filter = "((ASC files)| *.asc";
              fDialog.InitialDirectory = @"C:\";
  
              //Show Messagebox if the file was loaded (Source: MSDN - FileDialog.FilterProperty)
              if (fDialog.ShowDialog() == DialogResult.OK)
              {
                  MessageBox.Show("The File was loaded successfully.");
  
                  try
                  {
                      if ((fileStream = fDialog.OpenFile()) != null)
                      {
                          using (fileStream)
                          {
                              //Insert code for reading the stream here.
                              Spectrum newSpectrum = new Spectrum(chart1.Series.Count, fDialog.FileName,
                                 fDialog.SafeFileName, DataHandler.readSpectrumFromFile(fileStream));
  
                              addSpectrumToView(newSpectrum);
  
                          }
                      }
                  }
                  catch (Exception ex)
                  {
                      MessageBox.Show(ex.Message);
                  }
  
              }
          }
  </code></pre>
