Notes

A before and after energy chart for a fictional retrofit firm: two Proportion Bars in bar mode share one fixed total (the energy bought before the work), so the after bar stops short and the tinted remainder reads as energy no longer bought. Values sit inside the segments and Hide Values Narrower Than drops the ones that will not fit, two Stats carry the headline saving, and Spec Rows lists what was changed with the heat pump row highlighted. Keep both bars on the same total or the comparison stops being fair.
