Changing the formatting of a linked chart in Word

I've been using Office 2010 and have been copying excel charts into my word documents for some time. I particularly liked the functionality that allowed me to change the formatting of the chart in Word. Things like colours, size of fonts, etc. I've now moved to Office 365 where I find that I can no longer edit my chart's formatting in word. I've tried different linking and embedding options but so far the best solution I've come up with opens up my chart in Excel, and only allows editing in Excel.

I use both Excel and Word with the same chart data but previously I've been able to alter how the chart looks in Word. This allows the charts to appear to be different in each file but maintaining the same data (I hope that makes sense!)

It was easy in Office 2010 - Is this no longer possible in Office 365?

Thanks in advance

Figured it out!
The word document, even though I was editing it in Word 2013, was based on a template created in Word 2003 (or earlier!). As soon as I moved out of 'compatibility mode' the chart functionality returned.
