Changeset 561 for trunk/sources/HeuristicLab.CEDMA.Charting/ResultListView.cs

Timestamp:

Author:

Message:

• asynchronous downloading of agents and results from the CEDMA server
• created a chart that displays points as bubbles (scatter-plot + optional third dimension for the size of the bubble, larger bubbles are more transparent than smaller bubbles)

ticket #268 (Possibility to open the function-tree of any model (represented as point in the scatter-plot))
