Scaling a Graph

Data may extend beyond the graph's bounds or not fill the graph. Thus it will be necessary to adjust the x- and/or y-axis scale of the graph.

You can doing this Manually or by Autoscaling the graph. For more about these options, see below. Note: A tutorial covering graph scaling is available. Choose Open from the File menu, then look in the Tutorials folder to access it.

Autoscaling

This feature automatically adjusts the graph axes so all data will fit with little empty space. There are two ways to Autoscale a graph:

• Set up the graph to Autoscale automatically in the Axes Options Tab.
• Autoscale a graph a single time by clicking the Autoscale button in the toolbar or by choosing Autoscale from the Analyze menu.

Manual Scaling

There are several ways to set the axes endpoint values yourself:

Axes Hotspots

An easy way to change an endpoint value for either axis is to do any of the following:

• Click the largest or smallest axis value and edit the value.
• "Stretch" the axis by hovering the cursor over the axis until the cursor turns into a squiggly arrow. Click and stretch the axis.

Axes Options Tab

In the Axes Options Tab, you can enter values for the endpoints of both the x- and y-axes all at the same time.
