When displaying any metric over time, and there is missing data for some periods, currently line charts treat this as 0. I would like the option to simply connect the last dot/data point to the next data point with a straight line.

I do not want to interpolate values for the points in between as there are no data points for them. I just want a clear connecting line between the last point with data before the "gap" connecting to the first point of data after the "gap."
