[xb,yb] = stairs(y)
[xb,yb] = stairs(x,y)
stairs(y)
draws a stairstep graph of the elements of vector y
. A stairstep graph is similar to a bar graph, but the vertical lines dropping to the x-axis are omitted. Stairstep plots are useful for drawing time history plots of digital sampled data systems.
stairs(x,y)
draws a stairstep graph of the elements in vector y
at the locations specified in vector x
. The values in x
must be evenly spaced in ascending order.
[xb,yb] = stairs(y)
and [xb,yb] = stairs(x,y)
do not draw graphs, but return vectors xb
and yb
such that plot(xb,yb)
plots the stairstep graph.
x = 0:.25:10;
stairs(x,sin(x))
