Graphs - displaying multiple data

Afternoon

I'm attempting to display mutliple data on a graph form in effort to show variances between six stations but unsure how to present it clearly - I am a novice user of excel.

I need to have "stations 1 - 6" listed on either axis and for each station have listed 7 different groups with variances in values. Evidently the idea is to show the changes in the in the 7 groups across each station.

Any advice on the sort of graph to use or how to actual do this would be excellent as currently I can only get stations and one group to show :/
