Point Analysis View
Point Analysis View draws the point-to-point matrix configured in Point Analysis Controls: one cell per pair of selected points, colored by their similarity or distance. Its useful trick is that the heatmap and the map are wired together, so a cell you click becomes a line between two points in the space.
Where to find it
View → Quantitative → Point Analysis View, next to Point Analysis Controls. The Rich layout preset opens the pair together.
What it shows
The panel is titled Embedding Matrix once a matrix exists. Before that it shows one of:
- “Heatmap appears here…” when Analysis Type is None.
- “Please select at least two features to compare” when fewer than two points are checked in the Controls panel.
- “Loading matrix data…” while the matrix is being computed.
Axis labels are point titles, truncated to 12 characters once they run past 15. Two points whose titles truncate to the same string share a label, so give points distinct leading text when you plan to read the matrix closely.
The color scale is RdBu and it auto-scales to the values present, which means the palette does not carry a fixed meaning between runs. Under Cosine Similarity high values are close pairs; under Euclidean Distance high values are far pairs.
Interactions
- Hover a cell. The strip under the matrix reads “Comparing titles: A X B”, the value appears in the plot’s own tooltip, and the two points are highlighted on the map with a temporary connecting line.
- Click a cell. The cell is shaded grey and a persistent line is drawn between those two points on the map, colored by the value: red toward the positive end of the scale, blue toward the negative. In 2.5D the line arcs above the plane. Click the same cell again to remove the line.
Persistent lines accumulate, so you can click several cells and read the resulting web on the map. They are cleared by unselecting each cell.
How to use it
- Select a bag and open both Point Analysis panels.
- Trim the checklist in the Controls panel until the labels are legible.
- Scan for blocks. Contiguous blocks of similar color along the diagonal are groups of mutually similar points.
- Click the cells that interest you to draw those relationships onto the map, and look at where the linked points actually sit.
Limits
- The panel has no controls. Metric, target, and membership are all set in Point Analysis Controls.
- Labels are truncated and can collide; the hover strip shows the full titles.
- There is no export. Read values from the tooltip or the hover strip.
- There is no agent button in this panel.
