gnuplot-py-users Mailing List for Gnuplot.py

hi,

The new gnuplot uses 'wxt' as default terminal on unix which looks a lot
nicer than 'x11'.

And as you already know, pipes + mouse zoom don't work together. For me,
mouse zoom is a very important feature. So as long as there is no better
solution, could you please change the defaults? I'm sure most users would
benefit from this.

bye,
Martin Renold

There is no support in Gnuplot.py for missing data, but you can easily
define your own PlotItem that knows about missing values.  It might make
sense to use numpy's masked arrays for this purpose.

Or you can just write the values to a file (with question marks where
appropriate) and plot it from there.

Hi All.

I want to plot a series where some of the data points are missing. I have
come to know that gnuplot support 'set datafile missing' command using which
you can specify a missing y value with any character like '?', or '-' in the
datafile input.

How do i do this when using gnuplot.py? If I set one of the elements of the
input array to '?', it gives the following error:

[211 16:22:15] python plotseries.py
Traceback (most recent call last):
  File "plotseries.py", line 212, in ?
    myPlot = Gnuplot.Data(arange(maxDays), myDataPoints, title='my series
data', with="linespoints")

Thanks in anticipation,
