Figure 2.25
PCP with Multi-Modal Peaks at Right
running near the centers of each axis. We start the process by using the lasso tool
to quickly narrow down all axis filters to the target ribbon. See Figure 2.25 for a
view of the initial state before any filter sliders have been adjusted.
Click on the lasso tool, then move all the way to the left of the Crack axis at
a height safely above the target ribbon.
Drag the rubber band to the right and down across all axes to a point safely
below the ribbon on the Ridge axis.
Release at this point.
The plot should look similar to Figure 2.26. Now it is time to fine-tune the
filters. Begin with the Weight filters since the target ribbon on that axis is quite
visible.
Slide the top and bottom filter triangles toward the middle to eliminate
most of the observations except for those within the target ribbon. As you
narrow the Weight filters down, the ribbon becomes more distinctive near
the four other axes.
As needed, slide each of those filter triangles closer to the ribbon until you
have eliminated all non-ribbon observations. Your end result should look
similar to Figure 2.27.
