Create Bar Chart in PowerPoint with C# REST API

This article guides on how to create bar chart in PowerPoint with C# REST API. You will learn how to create a bar graph in PowerPoint with C# RESTful Service using a .NET-based Cloud SDK. It contains complete information on adding a chart and setting data.

Prerequisite

Steps to Add Column Chart in PowerPoint with C# .NET-based API

  1. Initialize the SlidesApi with a client ID and secret for adding a chart
  2. Upload the presentation file to the Cloud
  3. Create a new chart configuration object using the Chart class and set the chart type
  4. Add chart title and initialize categories for the chart
  5. Initialize the data series for the chart, create the data series, and add the first data series
  6. Initialize more data series for the chart if required
  7. Add the chart to the first slide of the presentation using the CreateShape() method and download it if required

These steps describe how to create bar chart in PowerPoint with C# .NET-based API. Create the SlidesApi object, upload the presentation, create a Chart object, set chart type, position, dimensions, title, categories and desired data series. Add the data series to the chart and add the chart to the first slide.

firstSeries.DataPoints.Add(new OneValueChartDataPoint { Value = 25 }); // Value for Group C
firstSeries.DataPoints.Add(new OneValueChartDataPoint { Value = 10 }); // Value for Group D
// Add the first data series to the chart

// Create the second data series

secondSeries.DataPoints.Add(new OneValueChartDataPoint { Value = 45 }); // Value for Group C
secondSeries.DataPoints.Add(new OneValueChartDataPoint { Value = 15 }); // Value for Group D
// Add the second data series to the chart
chartConfig.Series.Add(secondSeries);
// Add the chart to the first slide of the presentation
Chart createdChart = (Chart)slidesApi.CreateShape("MyPresentation.pptx", 1, chartConfig);
// Print the number of categories in the chart to the console
Console.WriteLine(createdChart.Categories.Count);
// Download the modified presentation from the cloud
Stream stream = slidesApi.DownloadFile("MyPresentation.pptx");
// Save the downloaded file to the local system
var fs = new FileStream("Downloaded.pptx", FileMode.Create, FileAccess.Write);
stream.CopyTo(fs); // Copy the stream data to the local file
}
