I am trying to use the free set of currency data from data market but I am struggling to have an appropriate display.
Here is what I do:
- download data in datamarket --> Essentials free --> Currency --> I take all 3 of them, for base currency (_dim-8olw_, ...), quote currency and all time.
- back in my app I pick curve graphic, use all time as dimension and exchange rate as measure. But I can only use 1 measure.
My concerns are: I expect to have the conversion rate EUR/USD, EUR/GBP, USD/EUR, USD/GBP; GBP/EUR; GBP/USD and let user pick the base currency and display two curves of exchange rates. But it seems there is only 1 column of data for datamarket, just a exchange rate.
Can anyone help me on this?
