Currently, dr_plot_vot() line charts connect consecutive data points directly, which means if dates are missing from the data, the line draws straight through the gap. This could visually implies a gradual change when the reality is zero volume for those periods.
Bar charts don't have this problem (no bar = obvious absence), but I think line charts need the date sequence completed and filled with zeros before plotting.
