编辑： Jan 2018-6-12

Hi everyone! I've got this graph and i'd like to put on the x axis the correspondant time windows of my data. For example, the first bar refers to a date from 11/2006 to 11/2008; then, i switch one month for each following bar, as following:

1st bar: 11/2006 to 11/2008
2nd bar: 12/2006 to 12/2008
3rd bar: 1/2007 to 1/2009and so on...Is there a way to set like this a vector to be used as unit of measurement on the x axis? Thank you a lot in advance

If it was not easy to do, how would i put a standard date vector as unit of measurement on the x axis?

在 MATLAB Online 中打开

image(M,'CDataMapping','scaled')
colormap([0,1,0;1,0,0])

M is a logical matrix, of dimensions (P,Treb) where P=80 and Treb=155. So, on the x axis i have the Trebs. They represent a specific time window; for istance, Treb=1 corresponds to 11/2004-->11/2006 and so on, switching month by month. I'd like to put the correspondant time window instead of 1,2,..., 155 of course for few Trebs values.

My question remains the same: "Treb=1 corresponds to 11/2004-->11/2006" does not clarify, how the time information is stored in Matlab. Please provide this detail.

Did you read the documentation of datetick already? Define the XData correctly in the image command, then datetick solves the problem directly.
