Use area full names in trend chart legends

[elizabeth-richardson]

Would be helpful to use the 'full name' (i.e., with area type acronym suffixed to it) in the legend to differentiate between areas with the same name. Currently only the first selection with the same name is plotted I think? (e.g., Fife CA, Fife ADP and Fife HSCP) Or do all areas with the same name cover exactly the same geographical area?
