plot with dates on matlab

Hi All, I have some historical time series prices for some assets in a matrix of size 295x34. (Matrix called Absy)

Also I have the corresponding 295 dates in another matrix (295x1) called dates. The dates are in the format of 20060606 20060613 etc (weekly).

I want to plot Absy but with the x axis being the corresponding dates.

When I do plot (dates,Absy) I get a wrong graph. Could someone help me.

Is 20060606 a number or a string?

One way:

Convert to a MATLAB serial date first, using datenum()

d = datenum('20060606','yyyymmdd')

then plot, and use the datetick() function.
