Hello everyone,

I’ve been trying to do a plot like this one to represent the tide displacements (east, north, and up).

 ![image1](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/6/66bfa3f94b70c103c3fa9dd1c48d09abc1a35c8e.jpeg)

I am trying to use pygmt.Figure.velo to do it. But I cannot get the ellipses varying in shape and orientation. What am I doing wrong?  
I am new using Pygmt and this is what I tried so far following an example I found here:

> df = pd.DataFrame(  
> data={  
> “Longitude”: lon,  
> “Latitude”: lat,  
> “Eastward”: ets,  
> “Northward”: nts,  
> “Major”: semimaj,  
> “Minor”: semimin,  
> “azimuth”: direc,  
> }  
> )  
> fig = pygmt.Figure()  
> fig.velo(  
> data=df,  
> spec=“r0.5/0.95”,  
> pen=“red”,  
> uncertaintycolor=“lightblue1”,  
> frame=True,  
> )  
> fig.show()

Thanks.
