Hi George, I don't know of an export _command_, as such, but it should be easy to do from the Veusz python console. Since Veusz is built on top of numeric python (numpy), all of the numpy I/O routines are available. A good reference page for them is http://docs.scipy.org/doc/numpy/reference/routines.io.html As an example, if you want to export the array 'data1' to 'filename.txt', you could run >>> savetxt('filename.txt', GetData('data1')[0]) which would save the values (though _not_ the error bars, unfortunately) to 'filename.txt'. Saving the error bars as well takes just a bit more work, since Veusz stores the data and error bars as separate numpy.ndarrays: >>> # first we combine the data and error bar columns into a single >>> numpy.ndarray: >>> d1 = column_stack([ v for v in GetData('data1') if v is not None]) >>> >>> # then we write it to a file >>> savetxt('filename.txt', d1) I hope this helps!
