Overview
React 100% Stacked Line Chart displays multiple series of data, ensuring that the cumulative proportion of each stacked element always totals 100%. Hence, the y-axis will always be rendered with the range 0–100. 
Marker
Markers support built-in shapes such as circles, rectangles, ellipses, lines, diamonds, triangles, pentagons, crosses, and pluses. Images can also be used as marker symbols for customized presentations.

Data label
Data labels display information about data points. Templates support custom label content using HTML elements such as images, divs, and spans. Labels can also be rotated to a specified angle.

Multiple axes
Use multiple axes to plot different data sets that widely vary from one other.

Customization
Customize the look and feel of the 100% Stacked Line Chart using built-in APIs.
