How to Create a Line Chart

Problem:
I am trying to create a line chart but line not showing data well. Here is the link to the demo for your reference.

Solution:
Your line chart is not showing data well because the y scale hasn't been well formatted. In ZingChart, scales can be formatted to start and end at specified values, and with specified intervals (or steps). Please read here for more details. We've modified your demo to make the the y scale look better.
