This issue is happening after upgrade the QlikView into Nov 2018 patch 1
Issue: Chart legend label/header is not showing or changing properly, but values are showing correct
Cause of this issue:
This issue is happening while the chart having more than 2 dimensions and one of the dimension is conditionally disabled ( Enable/disable based on a condition ).
Example case:
Chart having 3 dimensions and one expression.
Dimensions are Month, Category and Financial Year
Category and Month are Conditional dimensions.
In current scenario, Category is disabled, but it’s label is showing in the chart instead of 3rd dimension’s label.
