No water charts

For a month now, after a HA update, I haven't seen any water consumption graphs in the energy panel. There are readings, but the system doesn't display a graph. The reading sensor is clearly working; there are no errors. I see numerical meter readings, but no visualizations in the panel. The water consumption graph window is black (clear).
all year long, since I got the water meter reading it worked very well, after the last HA updates it stopped showing the graph
