Matlab plotyy painting double ordinate diagram example

Matlab plotyy painting double ordinate diagram example x = 0:0.01:20; Y1 = 200*exp ( -0.05*x). *sin (x); y2 = 0.8*exp ( -0.5*x). *sin (10*x); [AX,H1,H2] = Plotyy (x,y1,x,y2, ' plot '); Set (AX (1), ' Xcolor ', ' k ', ' Ycolor ', ' B '); Set (AX (2), ' Xcolor ', ' k ', ' Ycolor ', ' R '); Hh1=get (AX (1), ' Ylabel '); Set (HH1, ' String ', ' left Y-axis '); Set (HH1, ' Color ', ' B '); Hh2=get (AX (2), ' Ylabel '); Set (HH2, ' String ', ' right Y-axis '); Set (HH2, ' Color ', ' r '); Set (H1, ' LineStyle ', '-'); Set (H1, ' Color ', ' B '); Set (H2, ' LineStyle ', ': '); Set (H2, ' Color ', ' r '); Legend ([h1,h2],{' y1 = 200*exp ( -0.05*x). *sin (x) '; ' y2 = 0.8*exp ( -0.5*x). *sin (10*x) '}); Xlabel (' Zero to musec. '); Title (' Labeling Plotyy '); Q: Can I get rid of the tick with blue circle on the right? Due to the use of plotyy drawing, in order to make the diagram appear as far as possible, with Set (AX (1), ' Ylimmode ', ' auto '), but this may cause the left AX (1) and the right ax (2) The tick spacing is not the same, the effect is beautiful. Or can you make plotyy draw the same tick spacing on both sides of the graph so that the tick on the right side of the graph will overlap. A: If you just want to make plotyy a little more beautiful, you can use the following form of invocation: [AX,H1,H2] = Plotyy (...) where AX (2) is the handle to the right axes object, it can be set or get to deal with it, or it can be ytick off. A: You can also use the line statement to draw, there is no left and top lines. Q:plotyy (x1,y1,x2,y2,fun1,fun2), how should FUN1 and FUN2 be written? A: These two fun plotyy do not necessarily have to use two plots, such as the following example, a curve with plot, a semilogy x1=1:0.1:100; x2=x1; y1=x1; y2=x2.^3; Plotyy (X1,y1,x2,y2, @plot, @semilogy)

Matlab painting double Ordinate

A graphic with two ordinate scales
In MATLAB, if you need to draw two graphs with different ordinate scales, you can use the Plotyy drawing function. The calling format is:
Plotyy (X1,y1,x2,y2)
Where x1,y1 corresponds to a curve, x2,y2 corresponds to another curve. Horizontal axis of the same scale, the ordinate has two, left ordinate for x1,y1 data pairs, right ordinate for x2,y2 data pair.

The double y-axis coordinates can be implemented with PLOTYY (X,Y1,X,Y2)
Double x coordinates can be used
Set (GCA, ' xaxislocation ', ' bottom ', ' Xticklabel ', {' 0 ', ' 1 ', ' 2 ', ' 3 ', ' 4 '}) (assuming the x axis is labeled as 1,2,3,4)
Set (GCA, ' xaxislocation ', ' top ', ' Xticklabel ', {' 0 ', ' 1 ', ' 2 ', ' 3 ', ' 4 '})
Make the appropriate settings

There is still a problem: This setting method can be set for the minimum units of each axis, but the scale range (X-0~7), y1 ( -1~1) cannot be set.
