Hello Jake, Am I correct in understanding that your ultimate aim is to plot the roll center height as a function of the platform displacement? I think you can do this easier given the model you already have (posted in the other question). You are already recording the displacement variable in the model using a To Workspace block. You can do the same for the roll center height as well. In the RC Viz subsystem log the appropriate height data to the workspace. Screenshot below:
Run the model and find two variables in the base workspace. displacement and RCZ. Now you can simply plot them:
>> plot(displacement,RCZ)
>> title('Platform Displacement Vs Roll Center Height')
>> xlabel('Platform Displacement')
>> ylabel('Roll Center Height')
You will get the plot as shown below.
Is this what you are looking for?
