Hello Zach,

Thank you for the screenshot. I could suggest you two approaches in order to resolve this issue:

-          you could reduce the thickness of the line series so in case both series have similar values they will not overlap.

        .Series(s =>

        {

            s.Line("ActiveCustomers").Thickness(2)

                .XAxis("Label")

                .YAxis("Count")

                .ValueMemberPath(cc => cc.CustomerCount);

        })

-          you could change the scale of the chart axes by setting min I max values for the properties for minimumValue and maximumValue of your numeric axes.

    a.NumericY("Count")

                .MinimumValue(0)

                .MaximumValue(20);

Please let me know if this helps.
