of the curve.
4. Select a point on the curve and click to indicate the end boundary of
the shaded area. A region under the function is shaded based on the

Using Graph Trace
Graph Trace lets you move from one point on a graph to another in order
to analyze variations in the data. You can use Graph Trace mode to
explore the data for the following graphs.
• Graphs from Plot Function and Show Normal PDF
• Distribution curves (created in the Lists & Spreadsheet application)
• Movable Lines
