Factor sensitivity contour plot

[#1]

Hi,

In Profiler, one can enable Sensitivity Indicator, which is basically just a derivative of the function for each parameter.

I was wondering if it is possible (or if there exists some jsl script) to construct a 2D contour plot of sensitivity for 2 parameters. This would help me visualize which part of the 2D space is most sensitive to changes.

Or if there are other ways for such visualization? Perhaps via Contour Profiler, although I can't seem to interpret those curves in a similar manner as sensitivity values. But I can be wrong.

Thanks.

The Contour Profiler has a couple of options that might help you visualize sensitivity across 2 factors (.gif below).

1. The Surface Plot option brings up an interactive 3D visualization, where the steeper portions of the surface are the most sensitive to change.
2. The Contour Grid option overlays contours similar to a topographical map, so the more closely spaced lines would indicate areas that are more sensitive to change.

You could also use Prediction Profiler Red Triangle > Output Random Table to create a new data table, then use Graph > Contour Plot if you'd like more options with the contour plot (image below).

Many thanks, I didn't spot the Contour Grid option...
