Sri Lanka - Food Prices

Food prices data with HXL tags

Food median prices data with HXL tags. Median of all prices for a given commodity observed on different markets is shown, together with the market where it was observed. Data are shortened in multiple ways:

        - Rather that prices on all markets, only median price across all markets is shown, together with the market
          where it has been observed.
        - Only food commodities are displayed (non-food commodities like fuel and wages are not shown).
        - Only data after 2015-01-15 are shown. Missing data are interpolated.
        - Column with shorter commodity names "cmnshort" are available to be used as chart labels.
        - Units are adapted and prices are rescaled in order to yield comparable values (so that they
          can be displayed and compared in a single chart). Scaling factor is present in scaling column.
          Label with full commodity name and a unit (with scale if applicable) is in column "label".

        This reduces the amount of data and allows to make cleaner charts.
