i have Chart control that received real time data.
// MBit/Sec
Series seriesBps = new Series("bps");
seriesBps.Color = Color.Gray;
seriesBps.ChartType = SeriesChartType.Spline;
seriesBps.BorderWidth = 2;
seriesBps.Name = "MBit/Sec";
chart1.Series.Add(seriesBps);
//// Packets/Sec
Series seriesPps = new Series("pps");
seriesPps.Color = Color.SteelBlue;
seriesPps.ChartType = SeriesChartType.Spline;
seriesPps.BorderWidth = 2;
seriesPps.Name = "Packets/Sec";
chart1.Series.Add(seriesPps);
This is my timer tick event that need to add this data:
private void chartTimer_Tick(object sender, EventArgs e)
{
if (seriesBps.Points.Count() > 300)
seriesBps.Points.RemoveAt(0);
seriesBps.Points.Add(wf.BitsPerSecond * 0.000001);
DataPoint _point1 = default(DataPoint);
foreach (DataPoint item in chart1.Series[1].Points)
{
item.Label = "";
item.MarkerStyle = MarkerStyle.None;
}
chart1.Series[1].LegendText = chart1.Series[1].Name = (wf.BitsPerSecond * 0.000001).ToString("#,##0");
DataPoint Point1 = chart1.Series[1].Points[chart1.Series[1].Points.Count - 1];
Point1.Label = chart1.Series[1].Name;
chart1.Series[1].SmartLabelStyle.AllowOutsidePlotArea = LabelOutsidePlotAreaStyle.Yes;
chart1.Series[1].SmartLabelStyle.IsMarkerOverlappingAllowed = false;
chart1.Series[1].SmartLabelStyle.MovingDirection = LabelAlignmentStyles.BottomRight;
// --------------------------------------------------------------------------------------------------- //
if (seriesPps.Points.Count() > 300)
seriesPps.Points.RemoveAt(0);
seriesPps.Points.Add(wf.PacketsPerSecond);
DataPoint _point = default(DataPoint);
foreach (DataPoint item in chart1.Series[2].Points)
{
item.Label = "";
item.MarkerStyle = MarkerStyle.None;
}
chart1.Series[2].LegendText = chart1.Series[2].Name = wf.PacketsPerSecond.ToString("#,##0");
DataPoint Point = chart1.Series[2].Points[chart1.Series[2].Points.Count - 1];
Point.Label = chart1.Series[2].Name;
chart1.Series[2].SmartLabelStyle.AllowOutsidePlotArea = LabelOutsidePlotAreaStyle.Yes;
chart1.Series[2].SmartLabelStyle.IsMarkerOverlappingAllowed = false;
chart1.Series[2].SmartLabelStyle.MovingDirection = LabelAlignmentStyles.BottomRight;
chart1.ResetAutoValues();
}
This Chart work fine with the first Series but after add the second one received this error, i try to change the series name to something unique but i wont help
indexing starts at zero not 1, like any other for i loop . Move back each series by one.
private void chartTimer_Tick(object sender, EventArgs e)

I had the same problem, for me the answer was to first clear the series like this:
_chart.Series.Clear()
This is important if you build your Charts dynamically

Intro:
This pseudocode is based on Multiple chart areas in one column, however, when I enable many chart areas and all of them are aligned one above the other, the graphic height is getting lower while the axis X labels are getting away from the chart.
Let's see this in a deep way:
I have a panel which contains inside itself the chart.
Every chart area makes reference to a selected resource, so in this case, we have 5 chart areas as 5 resources selected on the checked list box.
From the third resource, I add 300 as the minimum scroll value of the panel, so the size of the chart increases, and the chart areas do not look excessively different in height every time we add a chart area.
Chart view for 13 Resources:
Chart view for 18 Resources:
Chart view for 21 resources:
And finally, chart view for 26 or more resoures:

I have a list of signals in a listview. When the user checks one, the values of the signals are being plotted on the chart. Moreover there is a vertical annotation which the user can drag across the graph and see the values for every x value. Each signal has one rectangle annotation that shows the Y value.
My problem is that when the user checks a new signal then the old rectangle annotations do not disappear.
Here is what I mean :
enter image description here
Here is my code so far :
List<RectangleAnnotation> anno = new List<RectangleAnnotation>();
List<Series> checkedItems = new List<Series>();
private void listView1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (listView1.FocusedItem != null)
{
double xFactor = 0.03;
double yFactor = 0.02;
CA = chart1.ChartAreas[0];
if (e.NewValue == CheckState.Checked)
{
anno.Clear();
Series s12 = new Series();
s12 = chart1.Series.Add((listView1.Items[e.Index].Text).ToString());
s12.ChartType = SeriesChartType.Line;
s12.MarkerStyle = MarkerStyle.Circle; // make the points stand out
s12.MarkerSize = 3;
checkedItems.Add(s12);
for (int i = 0; i < chart1.Series.Count - 1; i++)
{
anno.Add(new RectangleAnnotation());
anno[i].AxisX = CA.AxisX;
anno[i].IsSizeAlwaysRelative = false;
anno[i].Width = 20 * xFactor;
anno[i].Height = 8 * yFactor;
// VA.Name = "myRect";
anno[i].LineColor = Color.Black;
anno[i].BackColor = Color.Black;
anno[i].AxisY = CA.AxisY;
anno[i].Y = -anno[i].Height;
// RA[i].X = VA.X - RA[i].Width / 2;
anno[i].Text = "Hello";
anno[i].ForeColor = Color.Black;
anno[i].Font = new System.Drawing.Font("Arial", 8f);
anno[i].Text = String.Format("{0:0.00}", 0);
chart1.Annotations.Add(anno[i]);
}
for (int r = 0; r < num_rows; r++)
{
DataPoint dp = new DataPoint();
dp.SetValueXY(r, values[r, listView1.Items.IndexOf(listView1.Items[e.Index])]);
// chart1.Series[checkedListBox1.Items[e.Index].ToString()].Points.Add(dp);
s12.Points.AddXY(r, values[r, listView1.Items.IndexOf(listView1.Items[e.Index])]);
}
}
}
}
private void chart1_AnnotationPositionChanging(object sender, AnnotationPositionChangingEventArgs e)
{
int pt1 = (int)e.NewLocationX;
int i = 0;
foreach (var signal in checkedItems) {
double val = signal.Points[pt1].YValues[0];
foreach (var sim in signal.Points[pt1].YValues)
{
anno[i].Y = sim + 0.5;
}
if (sender == VA) anno[i].X = VA.X - anno[i].Width / 2;
anno[i].Text = String.Format("{0:0.00}", val);
i++;
Console.WriteLine(anno.Count);
}
I have thought of adding
chart1.Annotations.clear();
But it deletes all Annotations including the vertical. I only want to delete the rectangle annotations.
I had Gantt chart like this. I'd like to show AxisX2 with value is percentage that I prepared formula for it. I had challenges to show AxisX2 and set series for it.
Here is the Gantt chart I captured click here.
I expect to one more axis like this.
Please help, Thank you .

I am working with a RangeBar Chart in a c# form app. When I add the series to the chart they do no line up correctly. When I change the "DrawSideBySide=false" it works fine, but I need some of the series to be side by side.
Any help on this would be greatly appreciated.
My code is just a List of Series being populated and then those series being added to a chart.
I loop through this populating series and adding them to a series list.
Populating-
double yplot1 = (double)user.Projects[i].StartDate.ToOADate();
double yplot2 = (double)user.Projects[i].EndDate.ToOADate();
// Use a different series for each datapoint
Series seriesInstance = new Series();
//seriesInstance.Name = user.Name;
seriesInstance.Label = user.Projects[i].Name + " - " + (user.Projects[i].AllocationPercent * 100).ToString() + "%";
seriesInstance.AxisLabel = user.Name;
seriesInstance.ChartType = SeriesChartType.RangeBar;
// Have a start and end date so plotting 2 points on the y-axis
seriesInstance.YValuesPerPoint = 2;
//seriesInstance.CustomProperties = "DrawSideBySide=true";
//seriesInstance["PixelPointWidth"] = "200";
seriesInstance["MinPixelPointWidth"] = "150";
int xordinal = j;
seriesInstance.IsXValueIndexed = false;
seriesInstance.Points.AddXY(xordinal, yplot1, yplot2);
/*seriesInstance.Points[0].ToolTip = someTipText;
seriesInstance.Points[0].Color = resourceColor;
seriesInstance.Points[0].AxisLabel = xlabel;*/
seriesList.Add(seriesInstance);
Then I add all the series in the list to the chart
foreach (Series plotSeries in seriesList)
{
chart1.Series.Add(plotSeries);
}
// Force x-axis to show each task or resource
chart1.ChartAreas[0].AxisX.Interval = 1;
// Set y-axis to show each day of the month
chart1.ChartAreas[0].AxisY.Interval = 1;
ChartArea chartArea1 = chart1.ChartAreas[0];
chartArea1.AxisX.IsReversed = true;
// Set other y-axis properties
chartArea1.AxisX.ScrollBar.Enabled = true;
chartArea1.AxisX.IsLabelAutoFit = true;
chartArea1.AxisX.ScaleView.Size = 5;
chartArea1.AxisY.IsStartedFromZero = false;
chartArea1.AxisY.IsMarginVisible = false;
if ((lastDate - firstDate).TotalDays < 60)
{
chartArea1.AxisY.IntervalType = DateTimeIntervalType.Days;
}
else if (((lastDate - firstDate).TotalDays > 60) && ((lastDate - firstDate).TotalDays < 365))
{
chartArea1.AxisY.IntervalType = DateTimeIntervalType.Weeks;
}
else
{
chartArea1.AxisY.IntervalType = DateTimeIntervalType.Months;
}
// Set the y-axis labels
chart1.ChartAreas[0].AxisY.Minimum = firstDate.AddDays(-1).ToOADate();
chart1.ChartAreas[0].AxisY.Maximum = lastDate.AddDays(+1).ToOADate();
chart1.ChartAreas[0].AxisY.LabelStyle.Format = "ddd M/d";
// Force redraw of chart
chart1.Update();
I have an application with Chart control that dynamic updated with data via timer:
Series series;
MyObject obj...
series = new Series();
chart1.Series.Add(series);
//chart1.Legends.Add(new Legend("DifferentLegend"));
//chart1.Legends["DifferentLegend"].DockedToChartArea = "Default";
//chart1.Series["Series1"].Legend = "DifferentLegend";
//chart1.Series["Series1"].IsVisibleInLegend = true;
series.Color = Color.Blue;
series.ChartType = SeriesChartType.Line;
series.BorderWidth = 3;
chart1.Series.Add(series);
//chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.White;
//chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.White;
chart1.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisX.Maximum = 4;
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
chart1.ChartAreas[0].AxisX.IntervalOffsetType = DateTimeIntervalType.Number;
Timer tick:
private void chartTimer_Tick(object sender, EventArgs e)
{
series.Points.Add(obj.BitsPerSecond * 0.000001);
}
I want to change it style and remove the squares from the control:
How can I do that?
Try This:
chart1.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisX.MinorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MinorGrid.LineWidth = 0;
To disable X-Axis Labels from the Chart :
chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;
This then?
mainChart.ChartAreas[0].AxisX.MajorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisY.MajorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisX.MinorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisY.MinorGrid.Enabled = false;
