If the x values are the same for all y series then you only need to include it once: plot h1;y1,:y2
And for this example you don't need to explicitly state x at all because it will default to i.#y plot y1,:y2 However the format you have used is more general and will work for plots with different x values for each y series. ---Original Message----- > From: [EMAIL PROTECTED] [mailto:general- > [EMAIL PROTECTED] On Behalf Of Alex Rufon > Sent: Monday, 21 April 2008 21:07 > To: General forum > Subject: RE: [Jgeneral] RE: n00b plotting 2 lines > > Hi Ric, > > Thanks.
