MS Chart: X-AXIS labels repeating - c#

I am trying to create multi series line chart using MS Chart. I have created it successfully. But the problem is the x-axis labels repeation. Here is what is created
Can anyone tell me why the months are repeated? how can i avoid it?
UPDATE:
Here is the code:
DateTime[] xvals = {DateTime.Now.AddMonth(-1),DateTime.Now};
decimal[] gvals = {4.3,0};
decimal[] ypvals = {0,0};
decimal[] yvals = {3.5,0};
// create the chart
var chart = new Chart();
chart.Size = new Size(600, 250);
chart.BorderSkin.SkinStyle = BorderSkinStyle.Emboss;
chart.BorderlineColor = System.Drawing.Color.FromArgb(26, 59, 105);
chart.BorderlineWidth = 3;
var chartArea = new ChartArea();
chartArea.AxisX.MajorGrid.LineWidth = 0;
//Remove Y-axis grid lines
chartArea.AxisY.MajorGrid.LineWidth = 0;
chartArea.AxisX.LabelStyle.Format = "MMM";
chartArea.AxisX.MajorGrid.LineColor = Color.LightGray;
chartArea.AxisY.MajorGrid.LineColor = Color.LightGray;
chartArea.AxisX.LabelStyle.Font = new Font("Consolas", 8);
chartArea.AxisY.LabelStyle.Font = new Font("Consolas", 8);
chart.ChartAreas.Add(chartArea);
var series = new Series();
series.Name = "Y";
series.Legend = "Y";
series.ChartType = SeriesChartType.Line;
series.XValueType = ChartValueType.DateTime;
series.IsVisibleInLegend = true;
series.Color = Color.Red;
series.IsValueShownAsLabel = true;
series.BorderWidth = 2;
chart.Series.Add(series);
// bind the datapoints
chart.Series[0].Points.DataBindXY(xvals, yvals);
var series2 = new Series();
series2.Name = "YP";
series2.Legend = "YP";
series2.ChartType = SeriesChartType.Line;
series2.XValueType = ChartValueType.DateTime;
series2.IsVisibleInLegend = true;
series2.Color = Color.Yellow;
series2.IsValueShownAsLabel = true;
series2.BorderWidth = 2;
chart.Series.Add(series2);
// bind the datapoints
chart.Series[1].Points.DataBindXY(xvals, ypvals);
var series3 = new Series();
series3.Name = "G";
series3.Legend = "GG";
series3.ChartType = SeriesChartType.Line;
series3.XValueType = ChartValueType.DateTime;
series3.IsVisibleInLegend = true;
series3.Color = Color.Blue;
series3.IsValueShownAsLabel = true;
series3.BorderWidth = 2;
chart.Series.Add(series3);
// bind the datapoints
chart.Series[2].Points.DataBindXY(xvals, gvals);
// draw!
chart.Invalidate();
// write out a file
chart.SaveImage("D:\\cha.png", ChartImageFormat.Png);

Ok, I have got the solution.
I have just converted the
series1.XValueType = ChartValueType.Date;
series2.XValueType = ChartValueType.Date;
series3.XValueType = ChartValueType.Date;
TO:
series1.XValueType = ChartValueType.String;
series2.XValueType = ChartValueType.String;
series3.XValueType = ChartValueType.String;
and instead of using dates in the xAxisValues array used months name as string.
DateTime[] xvals = {DateTime.Now.AddMonth(-1),DateTime.Now};
TO:
string[] xvals = {DateTime.Now.AddMonth(-1).ToString("MMM"),DateTime.Now.ToString("MMM")};
Hope this helps someone else.

How to add labels both inside and outside chart

I want to add labels both inside and outside of a pie chart.
I have tried adding values to it, it works either inside or outside.
I want to display both VALX and VALY on my chart
How can I do this?
I want my chart to appear like this.
XmlNodeList xnList = xml.SelectNodes("/Report/Parameters/Parameter");
var chart = new Chart();
chart.Height = 600;
chart.Width = 900;
ArrayList xAxisData = new ArrayList();
ArrayList yAxisData = new ArrayList();
string title = "Motility";
chart.Titles.Add(title);
var chartArea1 = new ChartArea();
chart.ChartAreas.Add(chartArea1);
chart.ChartAreas[0].AlignmentStyle = AreaAlignmentStyles.All;
Series series1;
xAxisData.Clear();
yAxisData.Clear();
string seriesName1 = " ";
byte ColorIndex = 0;
series1 = new Series();
seriesName1 = "Pie Chart";
series1.Name = seriesName1;
series1.ChartType = SeriesChartType.Pie;
chart.Series.Add(series1);
chart.ChartAreas[0].Area3DStyle.Enable3D = true;
chart.ChartAreas[0].Area3DStyle.Inclination = 40;
chart.ChartAreas[0].BorderColor = Color.Black;
chart.ChartAreas[0].Area3DStyle.WallWidth = 20;
chart.Series[seriesName1]["3DLabelLineSize"] = "30";
chart.Series[seriesName1].IsVisibleInLegend = false;
foreach (KeyValuePair<string, ReportParameter> pair in T_NewChart.parameters)
{
chart.Series[seriesName1].Points.AddXY((pair.Value.Name), pair.Value.Values[0]));
if (ColorIndex == 0)
{
chart.Series[seriesName1].Points[0].Color = Color.Green;
chart.Series[seriesName1].Label = "#VALX";
chart.Series[seriesName1]["PieLabelStyle"] = "Outside";
chart.Series[seriesName1].BorderColor = Color.Black;
chart.Series[seriesName1].Points[0].Label = "Total";
chart.Series[0].Font = new System.Drawing.Font("Arial", 15F);
}
else if (ColorIndex == 1)
{
chart.Series[seriesName1].Points[1].Color = Color.Yellow;
chart.Series[seriesName1].Points[1].Label = "Non";
}
else if (ColorIndex == 2)
{
chart.Series[seriesName1].Points[2].Color = Color.Red;
chart.Series[seriesName1].Points[2].Label = "Few";
}
ColorIndex++;
}
chart.SaveImage("C:\\NewPie_chart.png", ChartImageFormat.Png);
I can only display the "Name", but I want to display the "Name" (VALX) outside the chart and the "Value" (VALY) inside the chart.

This produces the following result:
PROBLEM:
I can not figure out how to make it so that the title aligns itself above the respective y-axis, any ideas?
I don't think you do that.
Afaik the recommended workaround is adding more chart Titles.
You can style them as usual and to move them on top of a axis you can align them to the top left of the respective Chartearea.InnerPlotPosition:
ChartArea ca1 = thisChart.ChartAreas[0];
RectangleF rip1 = ca1.InnerPlotPosition.ToRectangleF();
Title ty1 = thisChart.Titles.Add("ty1");
ty1.Text = "Y-Axis 1\nTitle";
ty1.ForeColor = Color.DarkSlateBlue;
ty1.Position.X = rip1.Left;
ty1.Position.Y = rip1.Y;
Make sure to have enough space at the top of the chart for the titles..
Do note that the values of all ElementPositions, including InnerPlotPosition are in percent of the respective containers, i.e. of the ChartArea for the InnerPlotPosition and of the Chart for the ChartArea..

itextsharp table chart legends beneath bars

Can someone explain me how I can create chart like this one using itextsharp library.
As you can see here, this chart has attached table with legends to its bottom side. And each bar has year attached to it. I want to create something like that.
Second picture. This is what i have so far. I don't have year attached to each bar, and my legends are not beneath each bar like in top graph. If someone could guide me how to create identical graph like one on top i would be grateful. Thanks in advance!
How can I turn those labels to be displayed horizontally, and put those legends beneath years in table like one in picture number 1.

Chart messing zoom on ResetAutoValues

I´m using a chart to plot some infos from a Sensor. Everything is going right, until I reach the interval of 3660 points.
So, what I want to do is when my points reach that value, my chart will remove the first point and add the new one, take a look at the code:
if (graficoKVm.Series[0].Points.Count > 3660)
{
graficoKVm.Series[0].Points.RemoveAt(0);
graficoKVm.Series[0].Points.AddXY(DateTime.Now.ToOADate(), _sensorCampoEletroMagnetico.kVm);
graficoKVm.ResetAutoValues();
}
The problem is that, if the chart is zoomed, when it execute the graficoKVm.ResetAutoValues(); my zoom got messed up.
So far I´ve tried to store the zoom values and then apply the zoom after the reset, but I´ve failed implementing it. Here is the chart declaration:

Have you tried in your code to use Refresh or Update? When the index reaches 3660, the chart will be replotted with the Point saved in your series, no matter how much zoom you applied.
To make it work in the right way, I've done this implementation:
if (graficoKVm.Series[0].Points.Count > 3659)
{
graficoKVm.Series[0].Points.AddXY(DateTime.Now.ToOADate(), _sensorCampoEletroMagnetico.kVm);
if (!graficoKVm.ChartAreas[0].AxisX.ScaleView.IsZoomed &&
!graficoKVm.ChartAreas[0].AxisY.ScaleView.IsZoomed &&
!graficoKVm.ChartAreas[0].AxisY2.ScaleView.IsZoomed &&
!graficoKVm.ChartAreas[0].AxisX2.ScaleView.IsZoomed)
{
while (graficoKVm.Series[0].Points.Count > 3660)
{
graficoKVm.Series[0].Points.RemoveAt(0);
}
graficoKVm.ResetAutoValues();
}
}
So, if the chart is zoomed on any Axis, it will not reset the min and max value from each Axis. Eliminating the zoom problem.

How to change my chart control background color

This is my control:
seriesTraffic = new Series();
seriesTraffic.Color = Color.Black;
seriesTraffic.ChartType = SeriesChartType.Spline;
seriesTraffic.BorderWidth = 2;
chart1.Series.Add(seriesTraffic);
chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.White;
chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.White;
chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;
chart1.ChartAreas[0].AxisY.LabelStyle.Enabled = false;
chart1.ChartAreas[0].AxisY.Minimum = 10;
chart1.ChartAreas[0].AxisX.Maximum = 10;
chart1.ChartAreas[0].AxisY.Minimum = 10;
chart1.ChartAreas[0].AxisY.Maximum = 10;
chart1.ChartAreas[0].AxisY.Interval = 5;
chart1.ChartAreas[0].AxisY.Interval = 1;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
chart1.ChartAreas[0].AxisX.IntervalOffsetType = DateTimeIntervalType.Number;
var chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();
chart1.BackColor = System.Drawing.Color.Black;
chartArea1.AxisY.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisY.MinorGrid.Enabled = true;
chartArea1.AxisX.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisX2.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisX2.MinorGrid.Enabled = true;
chartArea1.AxisX.LineColor = System.Drawing.Color.Green;
chartArea1.AxisX2.LineColor = System.Drawing.Color.Green;
chartArea1.AxisX2.LineWidth = 1;
chartArea1.AxisX2.MinorGrid.Interval = 0.25D;
chartArea1.AxisX2.MinorGrid.IntervalOffset = -0.01D;
chartArea1.AxisX2.MinorGrid.LineColor = System.Drawing.Color.Green;
chartArea1.AxisY.LineColor = System.Drawing.Color.Green;
chartArea1.AxisY.LineWidth = 1;
chartArea1.AxisY.Maximum = 2D;
chartArea1.AxisY.MaximumAutoSize = 100F;
chartArea1.AxisY.Minimum = -2D;
chartArea1.AxisY.MinorGrid.Interval = 0.25D;
chartArea1.AxisY.MinorGrid.IntervalOffset = -0.01D;
chartArea1.AxisY.MinorGrid.LineColor = System.Drawing.Color.Green;
chart1.ChartAreas.Add(chartArea1);
i want to change my control style to similar to this:
i try to change BackSecondaryColor, BorderColor but it has no effect.

To change the background color of the chart, you will need to change the BackColor property of the ChartArea.
chart.ChartAreas["ChartArea1"].BackColor = Color.Black;
chart.ChartAreas["ChartArea1"].AxisX.MajorGrid.LineColor = Color.LawnGreen;
chart.ChartAreas["ChartArea1"].AxisY.MajorGrid.LineColor = Color.LawnGreen;
You could try to use something like this
var chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
var chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();
chart1.BackColor = System.Drawing.Color.Black;
chartArea1.AxisY.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisY.MinorGrid.Enabled = true;
chartArea1.AxisX.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisX2.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
chartArea1.AxisX2.MinorGrid.Enabled = true;
chartArea1.AxisX.LineColor = System.Drawing.Color.Green;
chartArea1.AxisX2.LineColor = System.Drawing.Color.Green;
chartArea1.AxisX2.LineWidth = 1;
chartArea1.AxisX2.MinorGrid.Interval = 0.25D;
chartArea1.AxisX2.MinorGrid.IntervalOffset = -0.01D;
chartArea1.AxisX2.MinorGrid.LineColor = System.Drawing.Color.Green;
chartArea1.AxisY.LineColor = System.Drawing.Color.Green;
chartArea1.AxisY.LineWidth = 1;
chartArea1.AxisY.Maximum = 2D;
chartArea1.AxisY.MaximumAutoSize = 100F;
chartArea1.AxisY.Minimum = -2D;
chartArea1.AxisY.MinorGrid.Interval = 0.25D;
chartArea1.AxisY.MinorGrid.IntervalOffset = -0.01D;
chartArea1.AxisY.MinorGrid.LineColor = System.Drawing.Color.Green;
chart1.ChartAreas.Add(chartArea1);
If the above does not work for you, I think that you should try to modify your control only in designer (using properties).
The background color is set by BackColor on your chart, you should also change the ChartArea BackColor to transparent.
Here a quick example, hope it will help:)
