Example 1

x = 0:0.01:20
y1 = 50*sin(x)
y2 = cos(x)
plotyy(x, y1, x, y2)

Example 2

op1 = struct
op2 = struct
op1.lineStroke = 'green'
op2.lineStroke = 'red'
op2.dashArray = '2 3'
x = 0:0.1:10
y1 = exp(-x).*sin(x)
y2 = 2*exp(x)
plotyy(x, y1, x, y2, op1, op2)

Example 3

options = struct
x = -10:0.1:10;
options.yAxisColor = 'blue'
options.y2AxisColor = 'green'
y1 = exp(-(x*2-1).^2)*5
y2 = exp(-(x/2+1).^2)/5
plotyy(x, y1, x, y2, options)

Example 4

op1 = struct
op2 = struct
op1.lineStroke = 'green'
op2.lineStroke = 'red'
op2.dashArray = '2 3'
op1.xAxisTicks = 4
x = [2003 2004 2005 2006]
y1 = [10 20 30 50]
y2 = [50 30 40 10]
plotyy(x, y1, x, y2, op1, op2)

Example 5

op1 = struct
op2 = struct
op1.yAxisScale = 'Log'
op2.y2AxisScale = 'Linear'
x = 0:900; A = 1000; a = 0.005; b = 0.005
z1 = A*exp(-a*x)
z2 = sin(b*x)
plotyy(x, z1, x, z2, op1, op2)

Example 6

x = linspace(0,10,200)
y1 = 200*exp(-0.05*x).*sin(x)
y2 = 0.8*exp(-0.5*x).*sin(10*x)
y3 = 0.2*exp(-0.5*x).*sin(10*x)
plotyy(x, y1,[x',x'],[y2',y3'])
