Line charts for regression should show an ID column along the x-axis

[gkronber]

For instance if the data are ordered by time the time should be shown on the x-axis.

r15296: created a feature branch from the trunk

r15297: added a parameter to DataAnalysisProblemData to select an id column and extended RegressionLinechartViewBase to show the id on the xAxis

r15298: removed commented code and unused usings

Comments:

• The branch does not compile on my machine (Errors in simulated annealing)
• -> Could not test the implemented feature

• IDataAnalysisProblemData & DataAnalysisProblemData
  • IMO IdVariable looks and sounds strange. What about IdentificationVariable, Identification, LabelVariable, ....
  • Why not programmatic setter for the IdVariable? I know it is cumbersome to set constrained value parameters by code, but it is even more so when no setter property is provided.
  • AllIds, TrainingIds, and TestIds could be unified by using a new method GetIds(IEnumerable<int> rows)
  • Why are only features with unique values for every row allowed?
  • Ids should only be reset if the dataset changes on not if the partitions are updated
  • Is it possible to change the ID after solution creation (e.g. for updating the labels in a line chart) or is this not considered?

Code in LineChartBase looks reasonable. However, all other views should be updated as well (EstimatedValuesView).
