I have two nx2 vectors:
date = date number
closep = closing price
I then want to plot the time series with logarithmic scale. Anyone who knows how to do this?
So far I've only:
tsobj = fints(date, closep)
plot(tsobj)

set(gca, 'YScale', 'log')

? With that tsobj and that plot() command, closep will be the Y axis, and the set() to log scale will change the axis scaling and the default y tick locations and default y tick label formatting
For example,
tsobj = fints([(now-(500:-1:401)/10).'], rand(100,2));
plot(tsobj)
set(gca, 'YScale', 'log')
the Y ticks will get labeled with powers of 10 in this example.
If you are looking for a different tick label format or tick positions, then the way to do that is going to depend upon what your MATLAB release. In particular are you using R2014b or later?
