# Paste your code here
#import os
from mtpy.modeling.modem import PlotResponse
#working directory and save path
wd='D:/mtpywin/mtpy/examples/model_files/ModEM_2'
savepath='D:/mtpywin/tmp'
respfn='Modular_MPI_NLCG_004.dat'
datafn='ModEM_Data.dat'
ro=PlotResponse(data_fn=os.path.join(wd,datafn),
                resp_fn=os.path.join(wd,respfn),
                plot_type=['Synth02'],
                plot_style=1,
                plot_z=False,
                )
ro.plot()
ro.save_figure(os.path.join(savepath,'response.jpg'),fig_dpi=350)
