Point Analysis Controls
Point Analysis Controls configures a point-to-point similarity matrix: how similarity is measured, which vector it is measured on, and which points take part. The matrix itself is drawn in the companion Point Analysis View panel.
Where to find it
View → Quantitative → Point Analysis Controls. You can also right-click the map with at least one point selected and pick Point Analysis under Analyze. Open Point Analysis View next to it, or use the Rich layout preset, which pairs them.
Preconditions
The checklist is filled from the most recently selected bag. Create and select a bag first: with nothing selected the panel has no items to list. Points without a title are left out, because titles are what label the matrix axes.
Every change to a control recomputes the matrix immediately. There is no run button.
Controls
Analysis Type
- Embedding Matrix computes the similarity matrix. This is the setting the panel forces on open.
- None empties the checklist and leaves the view showing “Heatmap appears here…”.
Similarity Metric
- Cosine Similarity: angle between the two vectors, so magnitude is ignored.
- Euclidean Distance: straight-line distance, so larger values mean points further apart. The color scale in the view does not flip with the metric, so read a cosine heatmap and a distance heatmap in opposite directions.
Target Field
Projection is the only option: the matrix is computed on each point’s projection vector. The control is a placeholder for other vector fields that are not yet selectable.
Item checklist
One checkbox per titled point in the selected bag. Unchecking a point removes its row and column from the matrix. Hover a truncated label to see the full title.
How to use it
- Select a bag of the points you want to compare.
- Leave Analysis Type on Embedding Matrix. The matrix appears in Point Analysis View.
- Pick a metric. Cosine Similarity for direction, Euclidean Distance for spread.
- Uncheck points until the axis labels are readable. Two points is the minimum.
- Click cells in the view to draw links between those points on the map.
Limits
- Only the most recently selected bag feeds the panel, and only its titled points.
- Requests that fail replace the panel with an Embedding Analysis Error card carrying the server’s message. There is no retry button; change a control to trigger a new request.
- There is no agent button in this panel.
