I wanted to generate a graph such that the x axis is common and we have y-axis(on left) and z-axis (on right).
So that two graph with same horizontal point and different vertical point is generated.
Is this possible in vewolf
cewolf doesn't support dual axes out of the box; you'll need to use a chart postprocessor. This isn't a good use case for cewolf, though. Unless you're already using it for other purposes, using JFreeChart directly might be a better approach.
