Still about plot_pathline in plot_crosssection

[wsc1008-cugb]

I want to use the "plot_pathline" to plot the CrossSection result, which from 0 layer to bottom. I have used the latest version of flopy, and try an example which is similar with the flopy3_modpath6_example.ipynb, there is such error:

`fig = plt.figure(figsize=(80, 25))

ax = fig.add_subplot(1, 1, 1, aspect='equal')

mx = flopy.plot.PlotCrossSection(ax=ax, model=swt, line={'row': 0})

ibound = mx.plot_ibound()

grid = mx.plot_grid(color='0.3', alpha=0.1)

quadmesh = mx.plot_bc('WEL', kper=4)

contour_set = mx.contour_array(hds, levels=np.arange(np.min(hds),np.max(hds),0.5), colors='b')

plt.clabel(contour_set, inline=True, fontsize=35)

mx.plot_endpoint(well_epd, direction='starting', colorbar=True)

for now, each particle must be plotted individually

(plot_pathline() will plot a single line for recarray with multiple particles)

for pid in np.unique(well_pathlines.particleid):

modelmap.plot_pathline(pthobj.get_data(pid), layer='all', colors='red');

mx.plot_pathline(well_pathlines, method='cell', colors='red')`

I'll take a look at this.

@wsc1008-cugb

the IndexError message shows changes to the code that does not match the source code within the flopy development repository.

lines 2759 and 2760 within the repository are:

nmin = np.min(v_norm[cell])
nmax = np.max(v_norm[cell])

instead of

nmin = np.min(v_norm[cell] + 1)
nmax = np.max(v_norn[cell] + 1)

Please update your version of flopy to the most recent repo version using

pip install -U https://github.com/modflowpy/flopy/zipball/develop

Thank you, But sorry, I have tried many times, it still doesn't work.

Unfortunately, the copy of your source code does not match that in the flopy repo based on the error message. If you remove the "+ 1" from 2759 and 2760 of plotutil.py you should not get this error. Flopy uses a zero based indexing scheme, the "+ 1" is causing your error.

I‘m so sorry to bother you agian, I mistook the image at first. I have tried without any change at the beginning, it didn't work. So then I added the "+1" and "-1" at 2759 and 2760 to make it work, but I failed agian. Here is the first time I tried. There is the same error.

@wsc1008-cugb Thanks for the clarification. I've recreated the issue and found that the modpath intersection method is not handling layered data correctly. I'm currently working on a fix for this.

@jlarsen-usgs Thank you very much, it works!
