Serge,
Thank you for the solution provided. It does the scaling job but the window size is limited to the screen size (whenever the scaled Window is bigger than the screen, my Scilab 5.4.1 on Win 7 crashes abruptly). It would be very useful to be able to display a scaled plot with scrolling bars, to be able to browse the plot details.

Subject: Re: [Scilab-users] Scaled plot displays in Scilab? You can proceed as follow. Note however that at least under windows it is not possible to create a window larger than the screen.

Hi Stanislav, Thanks but it does not guarantee that the interval [x0,x0+10] will be plotted over 1 cm of the screen... I think that one may have to use a function like xchange but, more info about the physical screen is still required. Regards Rafael G. From: users [mailto:[email protected]] On Behalf Of ?????????

For example: plot2d(x ./ 1000, y); Also you may use a logarithm scale of x-axis. Stanislav 09.01.2014 21:14, Rafael Guerra пишет: Hello, Does anyone know if it possible to generate scaled plots in Scilab? Say one wants to plot y=f(x), with x being a distance, at 1:1000 scale (i.e., 1 cm on the PC screen would correspond to 10 m along x-variable). Scroll bar may be needed, if for given scale plot is larger than physical screen. Thanks for any hints.
