Dear all,

I hope all ok at your side.

I have been trying to plot two cross section from the same map using “pygmt.project”, one vertical (NW-SE) and the other horizontal (NE-SW) cross sections. The projection are Depths Vs Distance.

So far I use one script to plot The NE-SW (A-A’) cross section (output: “231202\_CrossSection\_horizontal.png”) and another script to plot the NW-SW (B-B’) cross section (output: “231202\_CrossSection\_vertical.png”).

I was thinking to use " fig.subplot()" method, but I am not sure if "pygmt.project"will accept to work within the "fig.subplot()"methodology because I get this error (attached the script):  
[two\_projections\_subplot.txt](https://forum.generic-mapping-tools.org/uploads/short-url/i2SWPAb4mDWX9BJtP2X2umn6fuX.txt) (5.6 KB)

```
GMTCLibError: Module 'basemap' failed with status code 72:
basemap [ERROR]: Option -Y given more than once
basemap [ERROR]: Option -Y parsing failure. Correct syntax:
basemap [ERROR]: Offending option -Ya0i

```

The output I’d like to have seems like the example: [subplot\_advanced\_examples](https://www.pygmt.org/v0.3.0/tutorials/subplots.html)

Thank you in advance for any suggestion.
