I love this app because of the ease and simplicity. There are only a few buttons to learn! After downloading the app, tap ADD NEW CHART:
Enter the data into the provided columns
NOTE: Tap the home button in the top, left corner, tap the gear icon and select Sliders or Keyboard to determine which data entry tool you want to use. Keyboard is pictured below.
Experiment with the other buttons - the Chart Type, the Color Schemes, and the Share Options.
