Coverage Requirements Chart

hi! 

I have a question about the graphs that appear in the Dashboard, in specific Coverage Requirements Chart, this chart we use to measure and display the coverage we have of the requirements to the execution of our test cases, when we recorded the Case test, is linked with the requirement that was already previously registered. The problem is that not all test cycles, our power testing involves running all the requirements that we have recorded in the project, for example, we have 10 total requirements and the "test cycle 1" only 5 will test requirements therefore only the associated test cases run these 5 requirements. The problem we have is that in the graph of Coverage Requirements is showing us the percentage of total coverage requirements (of the 10 requirements), and if you only run in this cycle tests 5 requirements, then the graph inidca us that we still cover 50%, is there any way that the graph shows only the requirements that are running on a given cycle, or have any idea to solve this problem we have? 

Thank you.
