Labeling a pie chart to replace the legend

Standard pie charts in QlikView suffer from a legendary problem – the legend. The problem is that the eye needs to move back and forth between the chart and the legend to help make sense of the data.

In this recipe, we are going to remove the legend and use the Dual function to replace it with text besides each segment that identifies the information.

Getting ready

Load the following script:

LOAD * INLINE [
    Country, Sales
    USA, 1000
