Missing / different choices available (inside 'Change visualisation') for PAW charts

Troubleshooting


Problem

User has an existing chart in PAW. User clicks on the 'Change visualisation' button, which brings up a new screen where they can choose what type of chart/graph they want to display their date with.

User notices that some chart selections are not there (not available to select/choose). Why are some charts missing?

Symptom

Example:

In one PAW 2.0.37 environment, the following visualisation options were available:

  • Exploration
  • Bar
  • Column
  • Line
  • Heat
  • Packed Bubble
  • Point
  • Area
  • Stack Bar
  • Stack Column
  • Tree Map
  • Word Cloud
  • Line and Column
  • List

 

However, in a different PAW 2.0.37 environment, the following were available:

  • Bubble
  • Radial
  • Line and Column
  • Scatter Plot
  • Tree Map
  • Word Cloud
  • Area
  • Bar
  • Column
  • Line
  • Packed Bubble
  • Pie
  • Point
  • Radial Bar
  • List

Cause

There are several possible explanations:

  • Scenario #1 - The view has been configured differently
    • The number of rows and column dimensions in a specific view, will dictate the specific charts that are available.  PAW only shows the visualizations that can be rendered for the current view.
    • For more details, see article 'Visualizations available by view configuration'

 

  • Scenario #2 - The visualizations engine may be different (for example, one environment may be using a 'column based' visualization model)
    • In PAW versions 2.0.34 (or earlier) customers have the old/original (not 'column based') visualisation model
    • In PAW versions 2.0.35 to 2.0.37 (inclusive) customers are able to (optionally) change their visualizations engine to a 'column based' visualization model
      • However, by default 'column based' is disabled
    • In PAW versions 2.0.38 (and later), the 'column based' visualization model is enabled automatically (enforced - there is no option to disable it).
      • For more details, see article 'Changes to visualizations'

Resolving The Problem

Scenario #1

Modify your view to allow the visualisation that you require.

  • For more details, see article 'Visualizations available by view configuration'

 

Example:

In one real-life customer example, the solution was:

1. Enable the feature 'Column-charting' (see below in Scenario #2 for instructions)

2. Modify the cubeview so that there was only one element in the subset of the measure dimension.

 

Scenario #2

Fix:

This is by design.

  • For more details, see article 'Changes to visualizations'

 

Workaround:

If using PAW 2.0.35 to 2.0.37 (inclusive) it is possible to enable/disable the 'column based' visualization model.

Steps:

1. Launch PAW

2. Click on your name, then 'Administer'

4. Click on the button underneath 'Enabled' to toggle (change) the setting

- TIP: You will receive a message similar to the following, which you will need to confirm (before the changes are made):
