Hi I have taken the example from the samples off the microsfot website. The example is the realtime Date&Time for C#. The example works perfectly when using a short distance and basically running it exactly as it is however I need to be able to monitor my graph for atleast 45min-1hour and only then must the values start falling off. What I would like to do is have about 5min watch time and the rest of the plotted graph I would like to be able to scroll back. So below is the area that is the problem. I need to add the scale view in order to set the amount I can see on the graph before it scrolls(Which doesnt work as well), but the moment I make the scale view above 1 none of the X-Axis value labels are inserted and if so then only 1 of them are and no more. The code is a bit messy as this has been very frustrating. Can someone either assist or guide me to a better chart as the support and documentation of this chart is terrible.
private void startTrending_Click(object sender, EventArgs e)
{
// Disable all controls on the form
startTrending.Enabled = false;
// and only Enable the Stop button
stopTrending.Enabled = true;
// Predefine the viewing area of the chart
minValue = DateTime.Now;
maxValue = minValue.AddMinutes(120);
chart1.ChartAreas[0].AxisX.Minimum = minValue.ToOADate();
chart1.ChartAreas[0].AxisX.Maximum = maxValue.ToOADate();
// Reset number of series in the chart.
chart1.Series.Clear();
// create a line chart series
Series newSeries = new Series("Series1");
newSeries.ChartType = SeriesChartType.Line;
newSeries.BorderWidth = 2;
newSeries.Color = Color.OrangeRed;
newSeries.XValueType = ChartValueType.Time;
chart1.Series.Add(newSeries);
/*chart1.ChartAreas[0].AxisX.LabelStyle.Format = "hh:mm";
chart1.ChartAreas[0].AxisX.IntervalType = DateTimeIntervalType.Minutes;
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisX.MajorGrid.Interval = 1;
chart1.ChartAreas[0].AxisX.MajorTickMark.Interval = 0.5;
chart1.ChartAreas[0].AxisX. */
chart1.ChartAreas[0].AxisX.ScrollBar.Enabled = true;
chart1.ChartAreas[0].AxisX.ScaleView.SizeType = DateTimeIntervalType.Minutes;
chart1.ChartAreas[0].AxisX.ScaleView.Size = 1;
chart1.ChartAreas[0].CursorX.Interval = 0;
// start worker threads.
