I Used spire.xls to create a sheet and a chart but my problem is when I save a chart as a PDF it would be so inappropriate just need to justify the chart but don't know how I think it would be the problem with scale
Chart chart = sheet.Charts.Add(ExcelChartType.ScatterSmoothedLineMarkers);
//Set region of chart data
chart.DataRange = sheet.Range["A2:A" + (_state.NumberOfReads + 2).ToString()].AddCombinedRange(sheet.Range["F2:F" + (_state.NumberOfReads + 2).ToString()]);
chart.SeriesDataFromRange = false;
//Set position of the chart
chart.LeftColumn = 22;
chart.TopRow = 6;
chart.RightColumn = 32;
chart.BottomRow = 29;
//Set and format category axis title
chart.PrimaryCategoryAxis.Title = "Applied Pressure DUT.";
chart.PrimaryCategoryAxis.Font.IsBold = true;
chart.PrimaryCategoryAxis.TitleArea.IsBold = true;
//Set and format value axis title
chart.PrimaryValueAxis.Title = "Average of REF.";
chart.PrimaryValueAxis.HasMajorGridLines = false;
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = -90;
chart.PrimaryValueAxis.MinValue = 0;
chart.PrimaryValueAxis.TitleArea.IsBold = true;
chart.Legend.Delete();
//Loop through the data series of the chart
foreach (ChartSerie cs in chart.Series)
{
cs.Format.Options.IsVaryColor = true;
//Show data labels for data points
cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = true;
}
chart.PrimaryValueAxis.HasMajorGridLines = true;
IChartTrendLine trendLine = chart.Series[0].TrendLines.Add(TrendLineType.Linear);
chart.Series[0].TrendLines[0].DisplayEquation = true;
chart.Series[0].TrendLines[0].DisplayRSquared = true;
//chart.HasDataTable = true;
Image[] imgs = workbook.SaveChartAsImage(sheet);
Bitmap img = new Bitmap(imgs[0]);
img.Save(path + filePic, ImageFormat.Png);
and also look at the outputs

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.

}

}
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.
I have a project with multiple AxisY, with 3 series and and each series has its axisY associated. When I zoom, I have achieved that all the series have zoom but the scale of the axisYof the secondary axisY doesn't change, only that of the main series changes.
Original Chart:
Chart with zoom applied:
I have create the new axisY secondary with the code of microsoft (Project "Windows Forms Samples Environment for Microsoft Chart Control"):
public void CreateYAxis(Chart chart, ChartArea area, Series series, float axisOffset, float labelsSize)
{
// Create new chart area for original series
ChartArea areaSeries = chart.ChartAreas.Add("ChartArea_" + series.Name);
areaSeries.BackColor = Color.Transparent;
areaSeries.BorderColor = Color.Transparent;

areaAxis.BackColor = Color.Transparent;
areaAxis.BorderColor = Color.Transparent;
areaAxis.Position.FromRectangleF(chart.ChartAreas[series.ChartArea].Position.ToRectangleF());
areaAxis.InnerPlotPosition.FromRectangleF(chart.ChartAreas[series.ChartArea].InnerPlotPosition.ToRectangleF());
// Create a copy of specified series
Series seriesCopy = chart.Series.Add(series.Name + "_Copy");
seriesCopy.ChartType = series.ChartType;
foreach(DataPoint point in series.Points)
{
seriesCopy.Points.AddXY(point.XValue, point.YValues[0]);
}
// Hide copied series
seriesCopy.IsVisibleInLegend = false;
seriesCopy.Color = Color.Transparent;
seriesCopy.BorderColor = Color.Transparent;
seriesCopy.ChartArea = areaAxis.Name;
// Disable drid lines & tickmarks
areaAxis.AxisX.LineWidth = 0;
areaAxis.AxisX.MajorGrid.Enabled = false;
areaAxis.AxisX.MajorTickMark.Enabled = false;

// Adjust area position
areaAxis.Position.X -= axisOffset;
areaAxis.InnerPlotPosition.X += labelsSize;
}
UPDATE--------------------------------:
I have this news:
Now, the 3 axis update his scale but it comes out together, How to separate them?
The code is here:
chart1.ChartAreas[2].AlignmentOrientation = AreaAlignmentOrientations.All;
chart1.ChartAreas[2].AlignmentStyle = AreaAlignmentStyles.All;
chart1.ChartAreas[2].AlignWithChartArea = "ChartArea1";
chart1.ChartAreas[4].AlignmentOrientation = AreaAlignmentOrientations.All;
chart1.ChartAreas[4].AlignmentStyle = AreaAlignmentStyles.All;
chart1.ChartAreas[4].AlignWithChartArea = "ChartArea1";
I tried to decrease space between space between columns and also wanted to decrease width of columns, but I was only able to adjust width of columns not space between columns.
please help for solution. I really appreciate the effort.
Code snap: `
for (int i = 0; i < dss.Tables[1].Rows.Count; i++)
{
yValues[i] = Convert.ToDouble(dss.Tables[1].Rows[i]["admission"].ToString());
if (isDateRange == 1)
{
xValues[i] = dss.Tables[1].Rows[i]["mth"].ToString().Substring(0, dss.Tables[1].Rows[i]["mth"].ToString().IndexOf(" "));
}
else
{

}

}
chart1.Series[0].Points.DataBindXY(xValues, yValues);

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.

Hello I am having a hard time understanding how to get my column chart to be centered over the X-Axis label. IN the chart pic below you will see that I have columns based on 1/2 increments. For my positive series the data starts on the left and ends at the x-axis label. On my negative series the data starts at the x-axis label and continues to the right. How do I get these columns centered over the x-axis label. I don't understand why one series is displayed one way and the other series is displayed a different way.
