Error Chart
Error chart helps you visualize uncertainty or variability of data. This demo shows you how to create error bars on top of a regular line graph.
Key implementation details
Our main chart is just a line series and we add error bars by utilizing advanced bullet functionality in amCharts. Bullets can be all kinds of objects in amCharts and this case we create a Graphics bullet so we can draw an arbitrary shape according to our needs.

Create a line chart with error bars for 7 countries on a category X-axis. Each data point shows a value with a vertical error bar (line with horizontal caps at top and bottom) and a circle marker. Tooltips display both value and error amount. Include pan/zoom on both axes, an XY cursor that snaps to the nearest series, and entrance animation. Use amCharts 5 library.
