[scilab-Users] Plotting data with single x axis and two y axes

[Samuel Gougeon]

Hello Giri,
Here is a commented example showing a way to do what you expect.
There are certainly other ones, noticeably by using drawaxis()
instead of | in addition to newaxes();
Hope That Help
Regards
Samuel
--------
x=linspace(1,7,100);
y1=sin(x);
y2=cos(x)*67;

clf
plot2d(x,y1);
xtitle("Sample with 2 different Y-scales","X","sinus(x)")
legend("sin(x)",-5,%f); // -5 => above the left top corner, no frame
a=newaxes();    // Creates a new default system of axes on the same  
area of the window, and makes it the current one
a.filled="off"; // the background of the graphical area should be  
transparent, to leave the previous plot apparent
red=color("red");
plot2d(x,y2,axesflag=3,style=red);  // plots new data. axesflag=3  
means X at the bottom, and Y at the right
// Because the default
legend("67.cos(x)",[6,100],%f);     // above the right top corner, no frame
a.font_color=red;                   // sets color for ticks labels
a.axes_visible=["off","on","off"];  // cancels x axis (else red)
a.y_label.font_foreground=red;   // sets color for y-label
a.y_label.text="67.Cosinus(x)";  // set y label

   Hello friends:
I often have to plot data with common x axis values and two
independenty axes values. I would like the y axes to appear on the
left and right hand sides of the plots.  I would be grateful to anyone
who can point out how I can do this using plot2d (or any other way).
My data file has three columns (x,y1,y2).
Thanks for your help.
Sincerely,
