Hi,

I cannot run slice_demo1.py under examples directory. I had gnuplot
installed under /usr/bin. I am not sure why 'slice_' in not
implemented. Do I need to install other plotpackage? Currently I have
gnuplot and Matplot. Thanks,

The error message I had are:

scitools.easyviz backend is gnuplot
Traceback (most recent call last):
File "./slice_demo1.py", line 15, in <module>

Yes, you need to install VTK with Python support in order to use the
slice_ command. On Debian based systems you can do this simply by
installing the python-vtk package. You can then run slice_demo1.py
like this:

python slice_demo1.py --SCITOOLS_easyviz_backend vtk

Great!Johannes. It seems work now. The problem is that the graph disapeared quickly after displaying. How to make it stay there. Many thanks.

Happy New Year!

Hi,

see the troubleshooting section in the Easyviz documentation:
