Altair® Panopticon

 

X & Y Variable Configuration

The X and Y variables are available in Numeric Line Graph (Horizontal / Vertical), Numeric Needle Graph (Standard / Stacked / Grouped), Scatter Plot, and Surface Plot (Standard / 3D) visualizations.

However, in the Timeseries Surface Plot, only Y variable is available (along with Color and Details).

 X & Y Variable Configuration

  1. Click the down arrow icon to the left of the X or Y variable. Initially, the variable has an [Empty] value.

  1. Check the [Empty] box to enable this value.

Clicking on the [Empty] value highlights this section and currently displays as the associated value of the X or Y variable. By default, the value is set to 1.

 

For example, in this Surface Plot visualization, the Industry column is added as the breakdown, when the [Empty] value is selected, the X or Y axis will be set to 1 (0 to 1.00):

 

You can opt to modify the following properties:

Property

Description

Variable Title

The name of the associated variable to X or Y axis.

Value

Value of the X or Y variable.

Format

The format the numbers will be displayed in.

 

  1. To associate other columns from the data table, drag and drop them to the X or Y  variable area. Select one to display the corresponding configuration panel.

This displays the configuration panel.

  1. Enter a label for the X or Y variable in the Variable Title field.

You can parameterize the variable title to support dynamic schema in the dashboards.

  1. The Format field lets you specify the format that numbers will be displayed in. Panopticon Designer (Desktop) uses the same formatting rules as Excel.

The visible range for the X or Y variable can either be calculated dynamically (the default) or set between predefined limits by selecting Fixed Range radio button. This reveals the Min and Max text boxes and populates them with default values taken from the data set.

  1. You can also specify an aggregation method in the Aggregate field.

The default value is Sum.

The X or Y variable supports a large number of other aggregation types.

    • If the aggregation method is set to PercentOfTotal, the Display Net Value section enabled.

    1. If this is checked the Net Value will be displayed in brackets after the Percentage of Total in the detail popup.

    2. Then set the Format.

    • If you set the aggregation method to Percent of Total Change, the Reference is enabled that allows you to select a reference column to use.

    • If you set the aggregation method to Percentile, the Percentile drop-down list is enabled and displays a list of values that can be used to calculate the value of the selected percentile. Default is 50.

    1. If this is checked, the difference to total will be displayed in brackets after the aggregation value in the detail pop-up.

  1. Select the Divide By value to divide a number:

    • 1

    • 1000 (by a thousand)

    • 10000

    • 1000000 (by a million)

    • 1000000000 (by a billion)
