Array Indices?

[DaveG]

Hi
My learning curve for Python is long.

I'm running a script that was used in someone else's project and I need to change some parameters to suit mine. Trouble is I have no idea what these are and what they do, other than they feed into matplotlib.pyplot to form contours.

cmax=500 # color scale
lmin=400 # cutting from east 
lmax=550 # cutting from west
rmin=520 # north of caldera
rmax=700 # south of caldera

###### kolumbo data
kxx=xx[rmin:rmax,lmin:lmax]
kyy=yy[rmin:rmax,lmin:lmax]
kelevation=elevation[rmin:rmax,lmin:lmax]

This is the error message when running the script:

Error:
C:/Users/David/PycharmProjects/pythonProject2/venv/init_collapse.py:107: UserWarning: No contour levels were found within the data range.
  cs=contour(kxx,kyy,-kelevation,[collapse_depth])
Traceback (most recent call last):
  File "C:/Users/David/PycharmProjects/pythonProject2/venv/init_collapse.py", line 108, in <module>
    csp=cs.collections[0].get_paths()[2] # path
IndexError: list index out of range

The problem may relate to my input file of xyz coordinates that are used to form the contours.

I hope you can help.
Thank you
