Getting the most out of a Trellis bar chart, some tricks

    Getting the most out of a Trellis bar chart, some tricks.

     

    The Trellis chart can be useful for displaying the same chart over a dimension, but it has its limitations. This document aims to show how to get around some of those limitations.

     

    Issue

    • - No Sorting within the (2nd) Trellis dimension

         You may want to sort on the outcomes for each trellis chart separately, but the same order is displayed for all Trellis charts.

    • - Same values for the (2nd) Trellis dimension.

         You may want to display e.g. a top ten for each of the Trellis charts.

    Work around:

    • - Use a rank as second dimension and an expression for the dimension label

     

    Issue

    • - Fixed y axis for all Trellis charts

         The same min and max values are used for all Trellis charts axes

    Workaround:

    • - For the display of the bar use an expression to calculate the difference from the average of the 1st dimension
    • - To display the actual outcome, use an expression with values on datapoint.

    This way you are more likely to get the most out of the limited display area in a trellis chart
