how to use hist in plotyy

Hi

Does anyone know how to use hist in plotyy. I have calculated daily number of events by hist. Also I calculated pressure change over time. Now I need to plot the 2 plots by plotyy.(daily seismicity rate(hist) on left and pressure change on right y axis).

I am getting trouble how to use the hist in my plotyy? How I can do it?

Thanks!

Look at this example

t=1:10
x=randi(10,1,10)
y=sin(t)
hist(x)
hold on
plotyy(nan,nan,t,y)

Thank Azzi for the code. It is helpful.

Answer 2

[Walter Roberson]

[counts, bins] = hist(... the data to histogram);
plotyy(bins, counts, x2, pressure_change, @bar, @plot)

However, the bins probably do not span the same range as x2 does, which is probably going to lead to one plot or the other being squished badly. For that situation, plotxx from the file exchange would make more sense.
