2 sets of data, 1 x-axis different time periods

[Fungard]

I have a broken line graph with two sets of data.

Data set 1 I have monthly data
Data set 2 I have annual data

The X-axis displays months.

The y- axes are working fine, however data set 2 is being displayed as dots, is there a way to have excel draw lines between the dots?

Nevermind answered my own question but I'll leave it here for a reference point:

Chart Tools > Design > Data > Select Data > Hidden & Empty cells > Show empty cells as > Connect data points with a line.
