How to display images for data points in a WinForms Chart

In the WinForms Chart control, you can display images for data points by using an ImageList control. This allows you to add images to series symbols by setting the ChartSymbolShape property to Image and specifying the image using the ImageIndex property within ChartSymbolInfo class.

Steps to display Images for data points

Step 1: Adding an ImageList control to your form.

ImageList imageList = new ImageList(); 
imageList.ImageSize = new Size(15, 15);
imageList.Images.Add(Image.FromFile("Resources\\Flower.png")); 
imageList.Images.Add(Image.FromFile("Resources\\Star.png"));

Dim imageList As New ImageList()
imageList.ImageSize = New Size(15, 15)
imageList.Images.Add(Image.FromFile("Resources\Flower.png"))
imageList.Images.Add(Image.FromFile("Resources\Star.png"))

Step 2: Setting the ChartSymbolShape to Image

series.Style.Symbol.Shape = ChartSymbolShape.Image;

series.Style.Symbol.Shape = ChartSymbolShape.Image

Step 3: Assigning images using the ImageIndex property of the ChartSymbolInfo class.

series.Style.Images = new ChartImageCollection(imageList.Images);
series.Style.Symbol.ImageIndex = 1; // Index of image in ImageList
series.Style.Symbol.Size = new Size(15, 15);

series.Style.Images = New ChartImageCollection(imageList.Images)
series.Style.Symbol.ImageIndex = 1 ' Index of image in ImageList
series.Style.Symbol.Size = New Size(15, 15)

Output:
