I have a chart whereby I'd like to show data I already have, but display along the X axis the rest of the month (where the data does not currently exist). For example, As of today the graph would show data up to the 16th, but would have dates all the way to the end of the month (i.e. the 31st October). The idea being that this is a 'rolling' chart for the whole month, which would be populated when the data comes in.
