Problem creating a graph out of a check box list

Problem creating a graph out of a check box list

I have a form that asks for the name, age of a person (text and numeric fields respectively). It also ask to select dates from a check box list (4 options created). The idea is to organize football matches and teams on that dates based on the amount of people inscribed. I tried to create a graph report that shows in X axis the dates and in the y axis the number of people inscribed for this date. The graph does not read or recognize all dates available in the database, only few of them, so the graph is wrong. I share my place with support. I would appreciate a solution to this problem.
