I have a pie chart which shows null values as a pie with a count. I want to change the background color of both the pie slice with null values and the legend to 255,255,255. Currently the legend shows '-' and the pie slice shows 19 as count. Now I want both to show white color. What is the expression to be put in the chart background color so that both shows white. Please share the expression and this has to be put in the expressions background color referencing the dimension status am I right. (not in dimensions background color)
basically change color of status which is '-' to white so that it reflects in the chart and the legend. Please share the expression as I am not sure if this is a null or a - or a blank. But want to display this telling them these many values need to be updated at back end.
