# 5. Beginning: Plotting

## 5.1. Introduction

This use case shows a user how to plot cell and point data. Plotting can be along a line that cuts through your data, or a location with respect to time.

## 5.2. Plot along a line

• Open can.ex2.

• Apply.

• Drag the can around with the left mouse button until you can see the can.

• Select Filter → Data Analysis → Plot Over Line.

• Select the line that says ACCL (Magnitude), causing this row to turn gray.

• At the bottom of the Properties tab, change Chart Axes to Bottom-Right.

• Note below that the ACCL (Magnitude) color has been changed to blue.

## 5.5. Plot multiple points (statistics plot version)

• Edit → Reset Session.

• Open can.ex2.

• Apply.

• Drag the can around with the left mouse button until you can see the can.

• We want to plot numerous points over time. First, we need to select the points.

• On the Properties tab, display section, click on Root, turning on all of the points or cells.

• On the Properties tab, turn off everything, then turn on all variables VEL (Magnitude).

## 5.7. Plot min, max and average for all points of a block over time

• Edit → Reset Session.

• Open can.ex2.

• Apply.

• Drag the can around with the left mouse button until you can see the can.

• We want to plot all of the can points over time. First, we need to select the points.
