Previously, when displaying a custom graph with metric backend data where the lookback window was bigger than the graph's step size, a single sample was only valid for the next grid point, even if the same sample should contribute to additional grid points further down the graph. Now, a sample contributes to every grid point whose aggregation lookback window covers it.
Because the lookback windows of consecutive grid points can overlap, a single sample can now belong to multiple grid points instead of just one. As a result, graphs no longer show a gap directly after the last sample, and values are now consolidated consistently across the whole lookback window.
The stored data and your configuration are unchanged. Only the consolidation of samples onto a graph's grid is affected.
