Add interactive charts in Numbers on iPad
An interactive chart presents data in stages so you can emphasise the relationship between groups of data. You can use an interactive chart to show data like sales by group over time, expenses by department and population changes by region per continent.
The interactive chart below shows the growth of three species during a three-year period.
You can interact with the chart using a slider and buttons or buttons only.
To create these charts, you can add a blank chart to a sheet, then select the table cells with the data you want to use. Or you can select the cells first, then create a chart that displays the data. Either way, when you change the data in the table, the chart updates automatically.
Tip: You can learn about different chart types in the Charting Basics template. With the spreadsheet manager in browse view, tap 
at the top of the screen, then tap Charting Basics in the Basic template category. Tap the tabs near the top of the template (Column and Bar Charts, Interactive Chart and so on) to view the different sheets — each sheet explains a different type of chart.
