How do I include the depths of the plotted quakes on the map? And is it possible to view it in a cross-section? I’ve changed the values of my depths into negative but its still the same.

df = pd.read\_csv(‘Eq.txt’)

grid = pygmt.datasets.load\_earth\_relief(resolution=“30s”, region=[120.000,121.000,13.275,14.364,-200,0])

fig = pygmt.Figure()  
fig.grdview(  
grid=grid,  
perspective=[-200,20],  
frame=[“xaf”, “yaf”, “SE”],  
projection=“M20c”,  
zsize=“1.5c”,  
surftype=“s”,  
cmap=“geo”,  
plane=“1000+ggrey”,  
contourpen=“0.1p”,  
)

fig.plot3d(  
x =df.lon,  
y =df.lat,  
z =df.dep,  
style =‘c0.2c’,  
color=‘red’,  
pen = ‘black’,  
)

fig.savefig(“3d.png”)

Not sure but try to add perspective=[-200,20] below in fig.plo3d also.

It works! Thank you!. So the first perspective=[-200,20] applies only for the basemap and not for the whole map figure.

But I have one last question, how do I make the points(circles) in 3d? Because when I change the perspective (ex. -200,5) it only shows the side view of the circles.
