Identify if a specific field value is in current selection
I'm interested in creating a conditional for an expression that identifies whether or not a specific field value is selected, and if it is shows the expression in a line chart. I was able to use: fieldName = 'value', but that only works if the only value selected in that field is 'value'. However I would like this to work if there are multiple selections for that field, as long as 'value' is one of them. I had previously asked this question and was told to use WildMatch(concat(fieldName), '*value*'), but this is not working for some reason. Does anybody know how to solve this?
