Hi Chriz,
What you are missing in the Nevron Chart (compared to the ms chart) is the Series grouping:
=Fields!Measure.Value

Also, in order to replicate the ms chart and add the "Trend" series, you need to switch the chart to Combo -> XY Scatter
Your first series should be Point and the second one Line.

You can review the modified RDL and let us know if you have any questions.

Best Regards,
