The following are test scenarios to help validate the implementation.

Scenario 1:

1. Open discrete-color.vizx in VA, goto Worksheet 1
2. Change Index in Rows deck to Discrete
3. Change chart type to Bar
4. Move Index field from Rows deck to Color deck
5. Expected: The resulting chart should look like the screenshot in worksheet1.png

Scenario 2:

1. Open discrete-color.vizx in VA, goto Worksheet 1
2. Change Index in Rows deck to Discrete
3. Change chart type to Bar
4. Copy (ctrl-drag) Index field from Rows deck to Color deck
5. Expected: The resulting chart should look like the screenshot in worksheet1-2.png

Scenario 3:

1. Open discrete-color.vizx in VA, goto Worksheet 8
2. Change AGG(Calculation1) field in Color deck to Discrete
3. Expected: The resulting chart should look like the screenshot in worksheet8.png

Code Review:

There seems to be a problem with getting all possible values for discrete measure fields. Please look at the ColorValuesTableModel class on how it calculates the range for the measure value. We need to do something similar, but to determine all unique measure values instead of the range.

Hi Nhi,

Thanks for your suggestions, now I am able to populate values in Color Deck using changes (which are checked in under below revision no.). However, colors are not yet applied on the Area Data. Will work on it.

It's hard to review the functionality further due to the broken Scenario B8 here. Please fix Scenario B8 first.

Done testing of this feature. Hence, marking it verified.
