Daily Change in Labels

Example

Summary of settings

• Type of chart: Columns
• Mapping of y attribute: City
• Mapping of x attribute: Profit
• Filters: Two historical dates selected
• Options → Common attributes → Text is mapped to a formula, calculating day-to-day difference
• Other effects:
  • Positive changes with + and expressed in units of currency: FORMAT_STRING = "+$#,##0;$#,##0"
  • Color scale applied to Columns (color mapped to Profit)

Step-by-step instruction

1. Add new Chart Widget
2. Select Columns
3. If there are multiple cubes connected to your application, you must select the cube you want for the chart.
4. To map the x attribute, select the groups you would like to see on the vertical axis, in this case the City dimension
5. To map the y attribute, select the value (measure) corresponding to the horizontal axis, in this example Profit.

The chart displays with axes mapped:

6. To display day-to-day changes next to each of the columns, click Options in the legend area of the chart:

   

   In the Options popup, find attribute Text and map it to a formula (see below).

   

   Notice in the above screenshot the format applied to the newly created measure. Positive changes will be displayed with + for better readability (Formatting).

7. The formula computes the difference between profit as of most recent date (CurrentMember) and profit as of previous date selected (NextMember, since dates are normally sorted in reverse order). Therefore, for the purpose of this example, select two consecutive dates using filters.

    (
      [Measures].[Profit],
      [Time].[HistoricalDates].CurrentMember
    ) - (
      [Measures].[Profit],
      [Time].[HistoricalDates].CurrentMember.NextMember
    )
   

   The chart with the formula mapped to Text:

   

8. Finally, assign colors of the columns. Go back to Option popup (in the Legend) and map Color to Profit:

   

The chart is complete:
