Hi Guys, I have been fighting with it for some time and would like to know a solution. I want the 3D plot to be shown with a cube with actual equal length of x,y,z. Thanks, Sincerely, Jon |

But you didn't draw a square. As is clearly visible in the figure you attached, you drew a rectangle that is 2 units by 1 unit. The "set view equal xyz" command makes sure that the unit length is the same on all axes. I.e. the aspect ratio is 1. But it's still up to you to draw something with the right dimensions.

Thanks for your response. I did have points on x axis twice that of y axis, but x,y range are the same, both from -1 to 1. Would set view care about how many points along each axis or it only cares about the values to be plotted? BTW, why would the following two commands set term x11 size 10,600 set term x11 size 600,600 have no control on the output on the screen? Can anybody comment on that?

So if you had filled both x and y it would have been a square, right? Isn't that what you wanted? > Would set view care about how many points along each axis or it only cares > about the values to be plotted? Neither. "set view" cares about the coordinate system itself, regardless of what points you do or do not plot. "set view equal xyz" gives you an orthogonal coordinate system so that a line segment from [a,b,c] to [a,b,c+1] has the same apparent length as one from [d,e,f] to [d+1,e,f] and so on. > BTW, why would the following two commands > > set term x11 size 10,600 > > set term x11 size 600,600 > > have no control on the output on the screen? > > Can anybody comment on that? It controls the size of the next x11 plot window you open. It does not change what is already on the screen.

Yes. That is too old (Sept 2009). In that version the x11 terminal did not support control of aspect ratios.
