5.4 Histograms and Planets

If your dataset contains less than 8 numeric fields and no other categorical or text data, then you can visualize your clusters with the Histograms and Planets visualization.

Note: this is a Beta feature, so it may be change in the future.

The histograms visualization allows you to set values for your fields with the sliders and get a real-time calculation of the nearest cluster. You will also get the distance to the cluster centroid for the selected values. The histograms display measures for the clusters’ instances e.g. mean, median, maximum, minimum and sum squares.

The planets representation is very similar to the histograms view except it contains a two dimensional chart, in which you can see the predicted cluster in the center and its relative distance from the other clusters. See Figure 5.11 .
