Lesson 2 - Creating a Graph

You can create graphs in several ways in Grapher. Graphs can be created from the Graphs tab, with the graph wizard, from the worksheet, and from templates. All of these methods are discussed in the Creating Graphs topic. In the tutorial, we use the most common method, creating a graph through the Graphs tab Create group. We will create a line/scatter plot from an existing data set.

 

To create a line plot graph:

  1. If the worksheet window is still open, click the Plot1 tab. Alternatively, you can create a new plot window by clicking the File | New | Plot command.

Click on the Plot1 tab to select the existing plot window.

  1. Click the Graphs | Create | Basic | Line Plot command .

  2. In the Open Worksheet dialog, select the Tutorial.dat samples file, from the Samples directory. You can select the file in the file list section or in the Open worksheets section at the bottom of the dialog.

  3. Once the file is selected, click the Open button.

 

A line plot is created using the default properties. By default, Grapher uses the first two columns containing numeric or date/time data in the data file. With this data file, the X Axis is equal to column A and the Y Axis is equal to column B. 

 

By default, the line plot is selected after the graph is created. The selected plot appears with a bounding box around the outside and selection handles on the line.

 


The line plot is created with the default

settings and should look similar to this graph.
