Visualizations Axes

 

  

   

   

The X and Y axes of visualizations may include the following settings when accessed from the Breakdown section:

Setting

Description

Leaf Bar Thickness

The thickness of the leaf or lowest level of data.

Leaf Label Angle

The Label angle of the leaf or lowest level of data of the crosstab axis. Default is 0, accepts values between -90 and +90.

Inner Bar Thickness

The width or height allocated for the non-leaf components of the crosstab axis in pixels. Default is 80.

Inner Label Angle

The angle of the non-leaf labels. Default is 0, accepts values between -90 and +90.

Min Interval Length

The minimal interval in pixels between cross tabbed visualizations. Default is 20.

Max Interval Length

The maximum interval in pixels between cross tabbed visualizations. Default is 400.

Word Wrap

Determines whether to wrap the visualization axis text.

 

Some visualizations may also include the following X and Y axes settings:

  

       

Setting

Description

Scale

Determines whether the scale of the axis is Linear, Log, or Power.

·         Linear – a change between two values is based on addition e.g., 30, 60, 90, 120, 180, etc.

·         Log - a change between two values is perceived based on the ratio of the two values or based on multiplication.

Once selected, the Base control displays with the value of the common base for the logarithmic scale (i.e., 10).

For example: log10(x) represents the logarithm of x to the base 10 e.g., 1, 10, 100, 1000, etc.

You can opt to enter a new Base value then click .

NOTE: Value cannot be lower than 2.

·         Power – Works according to the SIGN(MEASURE)*LOG10(MAX(1, ABS(MEASURE))) formula. Works like the Log scale except it can handle negative values and every value between -1 and 1 is set to 0.

For example, for values between -100 and 100, the axis will be:

-100, -10, 0, 10, 100

Inverted

Determines whether the Y or Height axis (for Vertical) or X or Width axis (for Horizontal) is inverted.

Show Title

Displays an Axis Title label.

When enabled, you can opt to enter a custom Title for the axis which will override the title of the visualization variable.

Axis Bar Thickness

The margin in pixels for the axis. If set to zero, the axis is removed.

Preferred Tick Space

The preferred space in pixels between the minor grid lines across the axis.

Minor Grid Line

How minor grid lines are drawn across the axis. Allowed values:

None

·         Dotted

·         Dashed

·         Solid

Major Grid Line

How major grid lines are drawn across the axis. Allowed values:

·         None

·         Dotted

·         Dashed

·         Solid

Tick Format

Set to From Variable to use the format string that is on the current variable displayed in the axis. Set to Metric Prefix to format the Tick labels in the numeric axes using the metric prefixes.
