Defining an Axis for a Chart

You can define multiple axes for APM charts in which the font, line styles, colors, scaling, and positions are customized to suit your preference. The axis can then be applied to a data series.
An axis can also be selectively included based on the attribute of a class.
This topic describes how:
•
To Define Axis Identification and Settings
•
To Define Axis Lines and Ticks
•
To Define Axis Labels
•
To Define Axis Scaling
•
To Define Advanced Axis Settings

To Define Axis Identification and Settings

1.
Open the table configuration that includes the chart for which you want to define an axis.
2.
Select the Appearance tab, and then the Chart tab.
3.
Select the Axes tab and then click New. The Chart Axis Properties dialog appears, open to the General tab. For example:
Note: You can also create an axis from a chart’s data series, on the Graph Data Series dialog.
4.
Select an axis type. Your choices are XType or YType for X and Y axes, respectively.
5.
Enter a name for the axis.
6.
Enter the axis title to appear on the graph.
7.
Select the axis title font, color, and alignment.
8.
Select whether the axis position is Primary or Secondary.
9.
In the Settings area, you can enable the axis line. Select a color and specify the width.
10.
In the Format style box, enter a text pattern to format the axis line, if appropriate. Here is an example of x and y axes that use the Format Style text box. The x axis format style is:
{A:dd-MM HH:mm}
The y axis format style is:
{V} °F
The result is these axes:
Patterns can contain regular text and value placeholders in braces. To format numeric and date/time values, you can apply format specifiers. Use a colon to separate a placeholder and its format specifier.
Basic placeholders are:
{A} series point argument
{V} series point value
For more information about specifiers, see Format Specifiers.
11.
Select Interlaced if the axis colors are to be interlaced.
12.
Select Logarithmic if the axis is to use the logarithmic scale to display axis values.
13.
For x-axes only, select whether the axis is to have an X axis margin.
14.
When you are finished, close the axis’ Properties dialog.
15.
Repeat steps 3 to 14 for each axis you want to define.

To Define Axis Lines and Ticks

1.
Open the chart axis for which you want to define lines and ticks.
2.
Select the Lines and Ticks tab from the Chart Axis Properties dialog. For example:
3.
In the Major grid lines area, select Enabled to enable major grid lines for the axis and then select the color and width for the lines.
4.
In the Minor grid lines area, select Enabled to enable grid lines for the axis, and then select the color and width for the lines.
5.
In the Major tick line area, select Enabled to enable major tick lines for the axis, and then select the color and width for the lines.
6.
In the Minor tick lines area, select Enabled to enable minor tick lines for the axis, and then select the color and width for the lines.
7.
When you are finished, close the dialog.
8.
Repeat steps 1 to 7 for each chart axis.

To Define Axis Labels

1.
Open the axis for which you want to define labels.
2.
Select the Labels tab from the Chart Axis Properties dialog. For example:
3.
In the Labels area, select Auto fit labels, and then select the chart’s label properties that APM can adjust if necessary. Your options are:
•
Rotate
•
Stagger
•
Hide
4.
If non-numeric data are to be charted, select Non numeric data is charted and then you can select from the following information:
Setting Name
Description
Has a single label
Select this option to categorize all non-numeric charted data under one label.
Single label
The name of the label applied to all non-numeric data in the chart.
Single label orientation
The orientation of the label applied to all non-numeric data in the chart.
Join path for labels
The join path for non-numeric chart axis labels.
Attribute used for labels
The join path’s attribute that is used for non-numeric chart axis labels.
Labels ordered by
The attribute by which non-numeric chart axis labels are ordered.
5.
Repeat steps 1 to for each axis label that you want to define.

To Define Axis Scaling

1.
Open the axis for which you want to define scaling.
2.
Select the Scaling tab on the Chart Axis Properties dialog. For example:
3.
Select one of the following options:
Setting Name
Description
Axis scaling
The scaling for the axis. Select from one of the following:
•
Automatic – APM determines the scaling based on the values in the axis.
•
Tightly bound to banding values
•
Include 20% of next bands
•
Specified minimum and maximum – You must also include the minimum and/or maximum values or their attributes.
4.
Repeat steps 1 to 3 for each chart axis scaling that you want to define.

To Define Advanced Axis Settings

1.
Open the axis for which you want to define advanced axis setting.
2.
Select the Advanced tab from the Chart Axis Properties dialog. For example:
3.
Select the join path for the attribute that controls whether the axis will be included or excluded from the chart.
4.
Select a controlling attribute from the list.
5.
Repeat steps 1 to 4 for each advanced axis setting that you want to apply.
