Thers is no stair function but you can obtain this king of plot using the polyline_properties:
clf;plot(sin(linspace(0,2*%pi,40))) e=gce();//plot creates an entity of type compound p=e.children;//the handle on the polyline p.polyline_style=2; //set stair case mode Serge Steer Le 24/09/2015 05:11, Robert McLean MD PhD a écrit : > So here is what I did for the stairs graph: > > // we are going to make a stair step graphing program in scilab > // o------o > // o--o | | > // | | o---o > // o----o > // > // We take the vector (x1,x2,x3,...,xn) and (y1,y2,y3,...,yn) and instead of > // graphing a lines from the data points (x1,y1) to (x2,y2), (x2,y2) to > (x3,y3), > // etc., we graph (x1,y1) to (x2,y1) then (x2,y1) to (x2,y2), etc. > // > // the number of graphed points goes from n to 2n-1. > > // (x1,x2,...,xn) > // (y1,y2,...,yn) goes to > // (x1,x2,x2,x3,x3,x4,x4,...) > // (y1,y1,y2,y2,y3,y3,y4,...) > > function stairs(x,y) > n=length(x); > x_indices=int((1:2*n-1)/2)+1; // gives 1,2,2,3,3,...,2n-1,2n-1 > x_ss=x(x_indices); // the stair step graph's x values > y_indices=int((2:2*n)/2); // gives 1,1,2,2,...,2n-2,2n-2,2n-1 > y_ss=y(y_indices) > plot2d(x_ss,y_ss) > endfunction > > // We create an example: > n=10; > x=linspace(0,2,n); > x=x.*x; //irregularly spaced x interval points from 0 to 4 > y=sin(x*%pi); > stairs(x,y) > > > > -- > View this message in context: > http://mailinglists.scilab.org/How-to-replace-Matlab-stairs-function-in-Scilab-tp2615846p4032896.html > Sent from the Scilab users - Mailing Lists Archives mailing list archive at > Nabble.com. > _______________________________________________ > users mailing list > users@lists.scilab.org > http://lists.scilab.org/mailman/listinfo/users > _______________________________________________ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
