    Dynamic line chart background colours

      Hi gurus,

       

      I have a line chart of historic data, volume plotted against 'Historic Week Start Date'. I want my line colour to change based on historic Fiscal Year.

       

      I have currently achieved this by hard coding in the following in the Background Colour section of my expression:

       

      =if(HistoricalFiscalYear='FY11',rgb(70,137,164),

        if(HistoricalFiscalYear='FY12',rgb(171,167,17),

        if(HistoricalFiscalYear='FY13',rgb(141,25,8),

        if(HistoricalFiscalYear='FY14',rgb(236,129,0),

        if(HistoricalFiscalYear='FY15',rgb(114,85,37))))))

       

      This achieves the intended result:

       

       

      However, to account for the possibility of the data being loaded in for more / different fiscal years, I would like to make this expression dynamic.

       

      I have another field, 'HistoricalFYRow' which is a row count, which could potentially be used in the expression (as was finding it difficult to do max / min on the fiscal year field (FY11, FY12...).

       

      Suggestions of how to modify this formula, perhaps with a variable?

       

      Thanks!
