## [Pyx-user] help regarding the plot

 [Pyx-user] help regarding the plot From: Sudheer Phani - 2004-01-07 17:08:30 ```Hello Could any one help me with plot functions. The code for one of examples is like this g = graph.graphxy(width=8,y=graph.linaxis()) r = random.Random() d = [(i, math.exp(0.8*i+r.random())) for i in range(1,10)] g.plot(graph.data(data.data(d)),x=0,y=1) g.writetofile("lissajous") I am looking for some help with the plot function. In the line g.plot(graph.data(data.data(d)),x=0,y=1) what does x=0 , y=1 signify. If these arguments are not given (g.plot(graph.data(data.data(d))), I am getting an exception it says incomplete axis specification regds Sudheer ```

If you make plots with more axes, you can have x2, x3, etc as well. Certains styles allow also for other names, like dx for x error bars in the symbol style. There is no (not yet) default when ommitting those specifications needed to use the style. The symbol style needs an x and y value to be used at a xy-graph. Thats the general concept ...
