In queries where there are many variables in the legend box Explore puts them all in one line which cuts off the rest of the variables. This is applicable when the legend is located at the bottom of the query.
Please make possible to adjust the height of the legend when it's located at the bottom of the query so all variable can be seen. Otherwise, it doesn't make data readable when it's received in PDF via email. I'm aware it's possible to adjust the width when the legend is located on the right of the query, that also doesn't fit all of the variables in some of our queries
