I have created a matrix visual using Deneb. I am able to highlight the selected cell using the method described here simple-encoding-of-opacity-with-conditions.
I would like to highlight the whole row, i.e. all the rows in the dataset that have the same field value as the selected item for the field on the axis ( the matrix row). But I am unable to build the expression.
My goal is to create a transform which would return "Y/N" for each row in the dataset when it has the value for the "parent" field as the row which has the "selected" field equal to "on" (Named "IsParentSelected" in the picture below. target transformed dataset
I would appreciate if someone could help with the transform expression.
