Gradient chart view for regression solutions

[bburlacu]

As the name suggests, this view contains a chart plotting the gradient of the target variable with respect to a chosen input variable. The user may then vary the input value (by means of mouse interaction with the chart) in order to see how the target response changes.

The gradient chart supports synchronisation of backing data using a shared modifiable dataset, allowing the user to get a complete view of the target variation by arranging side by side multiple charts corresponding to different input variables.
