I tried to add dimension "day" to the tracking code report in the workspace, but it is seem to not support? only can show the date in a specific tracking code,just like below. How can i download the tracking code report by day in workspace? Thanks.
better use DataWarehouse for this, e.g. with metric "tracking code instances" and "daily" (or whatever you are interested in):
Use the day dimension first, then breakdown day by tracking code? Is that what you're looking for?
