How do I change the colours and styles of points in a Total/Average/Count graph based on the current parent field?
Note that a point gets drawn only when the parent field changes, i.e. the parent field will already have its next value by the time the point gets drawn. Hence, if you want to use the value of the parent field in your condition, you need to compensate for this. If your parent field increments by 1 every time, this can be done by using ParentField – 1 in the condition. Otherwise you will need to save the value of the previous parent field in a variable or in your queue/data source and use that in the condition.
