plot.xsec

xsec(grid, lon, lat, az, clip, length=2000)

Generates cross-section of a grid surface.

Arguments:

• grid (xarray.DataArray or str): grid object to plot

• lon (float): longitude of the starting point for the projection (on trench)

• lat (float): latitude of the starting point for the projection (on trench)

• az (float): azimuth of the cross-section line

• clip (pandas.DataFrame): clipping mask in ascii format

• length (int, optional): length of the projection. Defaults to 2000.

Returns:

(pandas.DataFrame): data for cross-section line and track

Example

import plot
# load in the synthetic test model as a slab_model instance
model = plot.slab_model("../output/exp_slab2_04-18","surface") # synthetic test slab made with the 04-18 database
# make a cross-section line and save to variable
line = plot.xsec(
    model.dep_grid, # run line through the depth grid
    128, # setting the line reference point to 128 degrees longitude
    1, # setting the line reference point to 1 degree latitude
    110, # setting the line orientation to 110 degrees
    model.clp, # using the model clipping mask
)
