Combo combo

The Comment Combo visualization makes it easy to build quickly a comparison visualization without having to build a table first. You can easily view trends in your data in a line/bar combination.

Use a Combo to:

  • Compare this week’s orders to orders at the same time last month (and last year).
  • Quickly analyze and compare multiple metrics (like Persons and Revenue) against one another on the same chart.
  • Analyze a metric against a function (such as Cumulative Average) over a time horizon.

Keep in mind that:

  • You can add multiple comparisons in a single Combo chart.
  • If you add one or more comparisons, they have to be of the same type, such as Time comparison.
  • You can add up to 5 comparisons.
  • You can apply up to 3 filters to a metric.
  • Calculated metrics are not supported in Combo charts.

Use

  1. Add a Comment Combo visualization. See Add a visualization to a panel

  2. From the drop-down lists, select a dimension for the X-axis and a metric for the Y-axis.

  3. Select the type of Line comparison that you want to use.

    Line comparison type Definition
    Time comparison

    The most common type of comparison - comparing this time period to 4 weeks ago, for example. If you selected Time comparison, make a secondary selection as to which time period you want to compare.

    LIne comparison with Time period selected and the secondary selection field for Time period.

    Function

    You could introduce a function like Average into the comparison. See the list of supported functions.

    LIne comparison drop-down menu showing Functions selected and a list of available supported functions.

    Secondary metric

    You could, for example, compare Revenue to another metric.

    A Combo chart comparing two metrics.

  4. Select Build.

    The output looks similar to:

    A Combo chart showing the current period in a bar chart and comparison period in the line chart

    The current period is shown in the bar chart. The line chart represents the comparison period. The dots on the line chart are known as bar bells.

Supported functions

If you select Function as the Line comparison type, a function of the metric chosen is returned.

Function
Definition
Column Sum
Adds all numeric values for a metric within a column (across the elements of a dimension)
Cumulative Average
Return the average of the last N rows.
Median
Returns the median for a metric in a column. The median is the number in the middle of a set of numbers. Half the numbers have values that are greater than or equal to the median, and half the number have values that are less than or equal to the median.
Cumulative
The cumulative sum of N rows.
Column Maximum
Returns the largest value in a set of dimension elements for a metric column.
Mean
Returns the arithmetic mean, or average, for a metric.
Column Minimum
Returns the smallest value in a set of dimension elements for a metric column.

Here is an example of the cumulative average of the Revenue metric:

Here is an example of a combo chart with both Cumulative average and Mean functions:
