Hello, I have 2d data where x coordinate is not given in usual ascending order (x1,...,x1+l; l>0), and instead in another, regular, but not ascending or descending order (for illustration: x1,-x1,x1+dx1,-x1-dx1,....).y is an array which corresponds to the way x is ordered. I have noticed that giving 'plot(x,y,type='l') produces a plot where the points are connected in a completely wrong way. It is as the plot/lines assumes an ascending order between the succesive y points ignoring the fact that they are not (it connects y(x1) with y(-x1), for x1+dx). I don't know whether this could be a bug, because maybe sorting the y coordinates appropriately and then interpolating lines plotting is too much to ask of the plot function. But, I've felt like sharing :-)
Additionally, 'points' function will plot the data properly.
