On top of the series style, you can set special styles for some special meaningful data points. The data point styles can make data presentation more focused and charts more intuitive and efficient.
For different chart types, the data point style supports the following customizations
backColor - The solid or pattern background color of the data point or point marker.
backColorTransparency - The background color transparency of the data point or point marker.
border.color - The border color of the data point.
border.transparency - The border color transparency of the data point.
border.width - The border width of the data point.
border.lineType - The border line type of the data point.
You can customize the chart's data point style with the below code:
