Basic Chart using Data Jar

I am very new to doing something like this and I have struggled trying to figure the out on my own. Would greatly appreciate any help or guidance.

I am trying to make a line chart that displays some basic metrics

Example:

  • volume
  • direct hour
  • performance

I want to be able to input the data daily and have it display on a chart. From there I could have it posted in a widget on my Home Screen.

Again any help would be appreciated.
Thank you,
