I need to make a chart showing the weekly activity for the current week, with each day of the week being a point on the X axis. Example:

This works great, but the problem I ran into is that if there was Wednesday today, then there is no data for Thursday-Saturday. Currently, the chart shows this by sending the row back to 0. Is there a way to make Google Charts stop drawing the line at a specific point and leave the rest of the data points empty?
I tried to skip missing values ββfrom the dataset, but that just makes it stretch Sunday-Wednesday across the entire chart.
