1. Scatter Plot �Axes: two interest measures. �Color (gray level) – a third measure. Figure 1: Scatter Plot[1] 4/29/2014 3

Two-key plot �Color – Order, the number of items contained in the rule. Figure 2: Scatter Plot[1] 4/29/2014 4

3. Grouped Matrix-based Visualization �Columns -- antecedent groups �Rows – consequents �Color – aggregated interest measure �Size of ballo 0 n -- aggregated support Figure 6: Grouped matrix with k=? [1] 4/29/2014 8

5. Parallel Coordinates Plot Figure 10: Parallel coordinate plot (reordered)[1] 4/29/2014 11

Parallel Coordinates Plot �To visualize multidimensional data. �X-axis -- the positions in a rule, i. e. , first item, second item, etc. �Head of arrow -- points to the consequent item. �The width of the arrows -- support �The intensity of the color -- confidence. 4/29/2014 12
