How to change the maxmum value on y axis in chart?

I have 6 line charts on a page and would like to compare them at a glance

The issue I have is the data is all scored out of 10 but the y axis on the chart only goes up to the highest figure in the dataset which is not always 10.

Ideally I would like to fix all the charts so that the y axis ends at 10

Is this possible?
