Main Question or Discussion Point

I am looking for a chart for each planet. This chart must contain each planet's angle from it's argument of perihelion for a particular time on earth time. I am not looking for an ephemeris, I don't think. I need the angle along the eliptical path of the planet or the true anomaly.

These JPL charts doen't give the Argument of Perihelion(PA). The charts do give Longitude of the Ascending Node(LAN) and the Longitude of the Perihelion(LP). The equation for this is:
PA=LP-LAN
These are 3D compound angles. Is there an easy formula to calculate this?
