Sliceplorer evaluation results
We want to understand if any change in function value is due to varying a single paramter or two parameters at once.

Gerber et al.
With this visualization technique the multi-dimensional space is mapped via a non-linear mapping into the two axes used for visualization:
x2. It is not really possible to back out what, if any, behavior due to the combination of
x2 in the graph is due to the variation of one, two, or multiple combinations of parameter values in the original function.
The contour tree does not take the spatial locations of the input samples into account. Therefore, it is not possible to discern either one-dimensional or two-dimensional relationships between the input factors and the output value.
With the correlate task it is vital to see the input parameter space somehow in order to judge whether any change in function value is due to changes in a single parameter or multiple parameters at once.
The HyperSlice view shows a 2D slice. It is easy to see the influence of each parameter and their combination by looking at the view directly.
Here we would like to understand what factors are contributing to the overall value. We can investigate one slice at a time (as the image shows) but that does not give a good intuition overall as to which, if any factors contribute in combination to any behavior.
