Dear Matlab community,
in advance: Many thanks for the great help I always get!
I am trying to plot a time series (in a column), with the simple following function:
The result is exactly as I hoped for:
However, I am trying to put dates on the x-axis. I have a separate column variable for that with the same dimensions, called 'ffdates': 192601 192602 192603 192604 192605 192606 192607 192608 192609 192610 192611 192612 192701 192702 ...
I would like to display those on the x-axis, but if I execute the respective command
i get this:
I suspect that the distortion comes from the date jumps 192612 to 192701. However, is there a way that I can simple use the variable 'ffdates' as x-axis labels?
Alternatively, I would also be happy with defining a date range from 07/1926 to 12/2014 to the x axis, in any date format.
Thank you very much in advance!

>> dn=datenum(1926,7+[0:(2014-1926)*12+5].',1);
>> datestr([dn(1));dn(end)])
ans =
>> y=rand(size(dn)); % some dummy data
>> plot(dn,y)
>> xlim([dn(1) dn(end)])
>> datetick('x','mm/yyyy','keeplimits')
Adjust ticks but won't have sufficient room to label every month by any stretch...
