How to make linemark stretch to end of x-axis with dates

Hi there, as you can see from the picture I have dates on x-axis in the format "MM-yyyy", I want the line and areamark to stretch to the end of the graph. You got any suggestions? thanks in advance :)

You can append new data to your data collection with x value equal some far earlier datetime and set the y value to first of your real data. Then apply xScaleRange to see only valuable range starting from second element
