I have line charts and I wish to show value a string value on the line chart at the beginning and end of the line. The string value I wish to show is concatenation of string and the value of that expression.
So the expression are (these are the three lines) with the Date as the dimension.
Exposure of A
Exposure of B
Exposure of C
in each expression I have Show Value attribute set as follows. This allows me to visually show the expression at two points only, the Start date and End date of the line.
