For the visual WITH the trend, try setting a visual level filter for Date to the same date range (12/1 - 12/31) and see if it gives you the same value as the other KPI. The other possibility is that their is something up with the measure you are using to calculate your KPI. Message 2 of 14.

Trend Filtering on Graphs

WebAbstract. This work studies the denoising of piecewise smooth graph signals that exhibit inhomogeneous levels of smoothness over a graph, where the value at each node can be vector-valued. We extend the graph trend filtering framework to denoising vector-valued graph signals with a family of non-convex regularizers, which exhibit superior ... WebAnalogous to the univariate case, graph trend filtering exhibits a level of local adaptivity unmatched by the usual \ell_2-based graph smoothers. It is also defined by a convex minimization problem that is readily solved (e.g., by fast ADMM or Newton algorithms). We demonstrate the merits of graph trend filtering through examples and theory.
