I hope, someone can help me. I have a line chart with three position lines, which indicates the budget and its lower und upper limit. Now I want to colour this interval. How can I do this? I tried the expression if(amount >= lowerlimit and amount <= upperlimit, lightblue()) in the background-field, but this will only colour the intervall, if the amount is in it. But I want to colour the interval for every amount.
