Select the decomposition tree icon from the Visualizations pane. The two mandatory properties that we need to bind with data fields are Explain by and Analyze property, as seen below. As part of my project activities, I sometimes have to deal with parent-child hierarchies and need to flatten them in Power BI. The visualization shows that every time tenure goes up by 13.44 months, on average the likelihood of a low rating increases by 1.23 times. It therefore shows us what the average house price of a house with an excellent kitchen is (green bar) compared to the average house price of a house without an excellent kitchen (dotted line). Why is that? Use the Decomposition Tree when you want to conduct root cause analysis or ad-hoc exploration. The analysis automatically runs on the table level. We can add drill-through fields by dragging and dropping them in the bottom-most area in the drill-through section. Measures and aggregates used as explanatory factors are also evaluated at the table level of the Analyze metric. You can use the Key influencers tab to assess each factor individually. Maximum number of data points that can be visualized at one time on the tree is 5000. Segment 1 also contains approximately 2.2% of the data, so it represents an addressable portion of the population. More Features which are avialable: Image Support (Web Url or Image stored in PowerBI), Vertical and horizontal orientation . In addition, the visual decomposition tree in Power BI allows data to be visualized across several dimensions.
