I realized I can't use dimensions in "Angle" or "Size" and I will really like my dimensions, say "Channel Type" to reflect the number of visits that is also broken down in columns by "year" and row by "device type".
I've tried converting the dimensions into measure and it doesn't seem to work. Appreciate some insight!
Can you please post a sample workbook in Tableau Packaged Workbook format (*.TWBX) so that we community members might be better able to suggest solutions or provide an example?
