XY Graph - Two plots overlapping

Hello,

Please find a screenshot attached herewith.

There are two images one is the graph plotted in MS Excel and the other one in LabVIEW.

I could replicate the same as what is obtained in MS Excel except the two plots i.e horizontal lines from point 1-2 & 3-4 .The two plots should be of two different colors. Although I have set them so in the properties tab of XY-graph they are not getting discriminated from the two horizontal plots of P1 & P2 as there is overlapping.

Also I want my graph to show the enthalpy and pressure values as what are shown in the excel graph.

I have also attached my VI in version 8.2.1 for the convenience. Thanks in advance

Best Regards,
