[Gnuplot-py-users] labeling question

[Martin P. <mb...@ps...>]

Hi,

I am trying to label my plots automatically through scripts -- ( very 
large data-sets, Ex**l doesn't like it)

y= []
steps = range(len(y))
         d = Gnuplot.Data(steps,y)
         g = Gnuplot.Gnuplot()
         g.title("Title")
         g.xlabel("X-label")
         g.ylabel("Y-label")
         g.label(("test label") at 5,5) <---- How do you automate this 
line?
         g('set data style linespoints')
         g.plot(d)
         g.hardcopy('output.ps', enhanced=1, color=1)


DATA:
|  x  |    y     |  code |
|--------------|--------|
|  1  |  0.50 |  A12  |
|  2  |  0.75 |  ZXC  |
|  3  |  0.45 |  GFS  |
|  4  |  0.23 |  AER  |
|  5  |  0.12 |  ASD  |
|  6  |  0.90 |  IOP   |
|-----------------------|
How do you make a graph, and label each of the 6 points with the, x and 
y value, or by its code?

your help is much appreciated,

cheers,

Martin.

Hello plotters,

I am very familiar with gnuplot, but just learning
gnuplot.py. Does anyone have any experience with
plotting stocks with financebars, candlesticks, etc?
An example script perhaps?

Thanks in advance,

Hi John,
I'm also just beginning with gnuplot.py. But enclosed you'll find a script
that plots an ohlcv financebar plot that works just fine. I managed to also
plot the dates on the x-axis.
w. k. regards, Joost Janse

Re: [Gnuplot-py-users] labeling question

Hello,

There is no explicit support for the "set label" command in Gnuplot.py, 
but you can easily do this using the ability to pass arbitrary commands 
to gnuplot:

    for (x,y,code) in data:
        g('set label "%s" at %g,%g' % (code, x+xoffset, y+yoffset))

where xoffset and yoffset are chosen so that the label does not 
overwrite the point itself.

Hope this helps,
Michael
