How to create WinForms PowerPoint pareto chart in C#, VB.NET?
This article explains how to create a pareto chart in .NET PowerPoint using Presentation.
Pareto is a sorted histogram where the columns are sorted in descending order and a line represents the cumulative total percentage.
Pareto chart created using Presentation
To create a pareto chart in PowerPoint using Presentation, you need to do the following steps.
Steps to create pareto chart
- Initialize chart
Create a chart object by calling the slide.Charts.Add method and specify the chart type to OfficeChartType.Pareto enum value.
//Create the chart IPresentationChart chart = slide1.Charts.Add(100, 10, 700, 500); //Set chart type to Pareto chart.ChartType = OfficeChartType.Pareto;
- Assign data
Set a range of data to chart’s DataRange property. To plot the series values in column and categories in row, set chart’s IsSeriesInRows property to false.
//Set region of Chart data chart.DataRange = chart.ChartData[2, 1, 8, 2]; //Set chart series in column for assigned data region chart.IsSeriesInRows = false;
- Apply basic chart elements
Add the basic elements like chart title, data labels and legend with the below list of properties.
- ChartTitle of chart object.
- Set TRUE to chart’s HasLegend property, to show the legend.
//Apply chart elements //Set Chart Title chart.ChartTitle = "Pareto Chart"; //Set Legend chart.HasLegend = false;
Applicable properties of pareto chart
Below is the list of other properties that is applicable for a pareto chart.
1. GapWidth
2. IsBinningByCategory
3. HasAutomaticBins
4. BinWidth
5. NumberOfBins
6. OverflowBinValue
7. UnderflowBinValue
8. ParetoLineFormat
NOTES:
1)Applying other properties unrelated to this chart might throw exception or the changes will not be reflected in the output document because those properties are not related to pareto chart.
2)As pareto chart is introduced in MS PowerPoint 2016, it can’t be viewed in MS PowerPoint 2013 and its earlier versions.
To know more about creating charts with various settings using Presentation, please refer the documentation.
The following C#/ VB.NET complete code snippet shows the creation of pareto chart using Presentation.
using Syncfusion.Presentation;
using Syncfusion.OfficeChart;
namespace ChartSample
{
class Program
{
static void Main(string[] args)
{
using (IPresentation pptxDoc = Presentation.Create())
{
ISlide slide1 = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Initialize chart
IPresentationChart chart = slide1.Charts.AddChart(100, 10, 700, 500);
chart.ChartType = OfficeChartType.Pareto;
//Assign data
chart.DataRange = chart.ChartData[2,1,8,2];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "Expenses";
//Set Chart Data
chart.ChartData.SetValue(2, 1, "Rent");
chart.ChartData.SetValue(2, 2, 2300);
chart.ChartData.SetValue(3, 1, "Car payment");
chart.ChartData.SetValue(3, 2, 1200);
chart.ChartData.SetValue(4, 1, "Groceries");
chart.ChartData.SetValue(4, 2, 900);
chart.ChartData.SetValue(5, 1, "Electricity");
chart.ChartData.SetValue(5, 2, 600);
chart.ChartData.SetValue(6, 1, "Gas");
chart.ChartData.SetValue(6, 2, 500);
chart.ChartData.SetValue(7, 1, "Cable");
chart.ChartData.SetValue(7, 2, 300);
chart.ChartData.SetValue(8, 1, "Mobile");
chart.ChartData.SetValue(8, 2, 200);
//Set Category values as bin values
chart.PrimaryCategoryAxis.IsBinningByCategory = true;
//Formatting Pareto line
chart.Series[0].ParetoLineFormat.LineProperties.ColorIndex = OfficeKnownColors.Bright_green;
//Gap width settings
chart.Series[0].SerieFormat.CommonSerieOptions.GapWidth = 6;
//Set Legend
chart.HasLegend = false;
//Saving and closing the Presentation
pptxDoc.Save("ParetoChart.pptx");
pptxDoc.Close();
}
}
}
}
