1181361 - `enumerated` values should show bar graphs and tables without "end" values

Status: RESOLVED FIXED

(Data Platform and Tools :: General, defect)

Description

[Jared Wein [:jaws] (please needinfo? me)]

Histograms that are defined as "enumerated" should show a bar graph with each enumerated value on the X-axis centered horizontally underneath the respective bar.

We should also remove the "end" column from the tables, as they are useless at best and at worst confusing.

For example, this bar graph:

10 |
   |     |||
 5 ||||  |||
   ||||  |||  |||
 0 ||||  |||  |||
   ------------------------
   0    1    2    3 

should be displayed as:

10 |
   |     |||
 5 ||||  |||
   ||||  |||  |||
 0 ||||  |||  |||
   ------------------------
     0    1    2 

And the same for the table representation:

Start |  End | Value | Percentage
---------------------------------
  0       1      2         20%
  1       2      3         40%
  2       3      2         20%

Should be written as:

 Key |  Value | Percentage
---------------------------------
  0        2         20%
  1        3         40%
  2        2         20%
