Need Help with Line Chart

[Anonymous]

Hey,I have shared the PBIX file with you . Page 1 is my required output but my legend should have  data points with same color for few of the ESN based on the model column.( Same color for all the ESN having same model). Page 2 is the one where all the data points merge if I select model as legend which is not something i am looking for. Can anyone please help me out here?

Thanks in Advance!

we need to display the damage value vs the totals hours a particular unit ran where customer should be able to differentiate total number of units(ESNs) per model and how their behaviour (trend) varies with respect to other models!
