Asked by Locks on 21 Apr 2013

Hi,

I have a plot for two different time series which both must be shown in the same figure. the problem is now, that for one dataseries, the y axis should be from 1000 to 1500 and for the other from 20 to 50, how can I do that?

Accepted answer

you can use plotyy function

plotyy(x,y1,x,y2)

thanks! this is working with the code below:

dates=dataSet(:,1);

%SPX y1=dataSet(:,2);

%VIX y2=dataSet(:,3);

plotyy(dates,y1,dates,y2);

set(gca,'Box','off')

but there is now another problem, the lines aren't starting at the left axis but there is a space between the left y axis and the line plotted in the graph and the same goes for the right axis.

I tried to use those comands:

% axis([8.5 11.5 0 1500]); % set(gca,'xtick',9:0.5:11.5)

but I am not sure how I can use them when I have two differnt axis
