Making charts isn't just for school assignments. For work, extracurricular assignments and even your own problem-solving, they are a useful way to quickly make sense of data. The type of app you select for a chart should depend on what kind of chart you want to make. For example, you can make charts from equations, pie charts from spreadsheet data or a flow chart to show a process or brainstorming session.

Drawing Charts With Equations

Step 1

Launch the Quick Graph app after installing it from the App Store.

Step 2

Tap the "+" icon at the top of the screen. The onscreen keyboard launches. Type an equation and tap "Done." A two-dimensional chart appears on the screen as determined by your equation. Alternatively, tap the "Library" icon, which looks like an open book, and select an equation from the list that appears.

Step 3

Tap the button at the top of the screen that looks like a crosshair or target symbol. The 2D chart turns into a 3D chart. Tap the crosshair again to return to the 2D chart.

Step 4

Drag your finger across the chart to rotate it. To select a dark or light background, or to make the axes appear or disappear, tap the "Settings" icon.

Making Pie Charts

Step 1

Launch the Pie Chart 3D Free app after downloading it from the iPad App Store. A sample chart is displayed on the screen, which you can customize to your needs.

Step 2

Tap any slice of the pie chart to edit it. A new screen appears so you can change its size according to your own values, change the color or add a label to the slice. You can also move the slice position in the chart or remove it from the chart on this screen. Tap "Done" when you are finished to return to the main screen.

Step 3

Tap the "Add Slice" button to include a new slice in the chart. Tap the gear-shaped settings button at the bottom of the screen to change the chart title, specify unit values, or turn labels off or off. This app requires payment to print or share your chart; however, you can work around this by taking a screenshot. Press the Home button and Sleep/Wake button simultaneously on the iPad; screenshots appear in your iPad's camera roll.

Making Flow Charts

Step 1

Download Idea Sketch from the App Store and open it. Tap the large blue "Create an Idea" button.

Step 2

Tap the "+" button to create a shape. Type a name in the text field, which appears in the center of the shape. Select any of the shape icons, which include a circle, an ellipse and a square. You can also change the color of the shape and even attach a photo by tapping the "Attach Image" button.

Step 3

Tap the "+" button again to add additional shapes. Tap and hold a shape to select it for editing, or drag the shape to move it. To create a line between two shapes, tap one and then tap another. The line is created automatically between them.
