• Graph—This field appears on the Y Axis tab only and displays a list of subgraphs when they are available. Use subgraphs to plot multiple sets of data that share a common X axis but have different Y axes. From the list, select a subgraph for which you want to customize the Y axis.

• Axis Label—Use the input field to edit an axis label. The label is a textual line that appears next to each axis. To change the style, color, and size of the label's font, click Text Style. Click or clear the Display Axis Label check box to turn the axis label on or off.

• Range—Change the range of the axis. You can use this area to modify minimum and maximum values so that the window displays a specified segment of the graph.

• Tick Marks—Set the number of major and minor tick marks on the axis.

• Tick Labels—Change the alignment of value labels for the major tick marks. To change the style, color, and size of the font, click Text Style.

• Grid Lines—Select the style for the grid lines. To change their color, click the color selection button.

• Axis—Modify the thickness of the axis. To change the axis color, click the color selection button.

• Scaling—Use this area to adjust the scale for your graph:

◦ Log Scale—Change the values on the axis to a logarithmic scale. Using a logarithmic scale can provide you with additional information that you may not be able to see on a normal scale.

◦ Scale—This field appears on the Y Axis tab only. You can use it to change the scale of the Y axis.
