# Question regarding data grid

Hi I have a data set on a 0.5 grid, the dimension for x is 141, y is 71 and t is 38. I am trying to calculate the z score which I already did. I am trying to plot the the Z scores on a time series but since is greater than two dimensions is not possible to do it. Is there anyway to work around this without ruining the yearly data? Thanks in advance for your help

Attach some example and data

The uploaded file contains a single variable with size 1x71x38. If that is correct, just use the squeeze function to remove the singleton dimension.
Z = squeeze(Z);
The new size of Z is 71x38.
From here you can create a line plot for each column
plot(Z)
or a 3D surface
surf(Z)

I'm pretty sure this plot was created using the code
plot(Z(:))
Here, the values of X represent the index of the data point. The command Z(:) turns the entire array into a one-column vector. You can see that syntax described in this doc page. What that means is all the columns were placed head-to-tail. There are 71*38 data points, or 2698.

I am trying to have one line for the 38 years which I got earlier but with the frequency which is 2698 instead of the years. When I was trying to do the plot the error message I was getting was that the vectors were not the same lenght. I am new to matlab i have spent hours trying to get this graph right. But I guess thats part of the process of learning to use something new.

Yes, learning requires some practice. If you are brand new, have you gone through MATLAB Onramp? It might help introduce you in a guided, incremental way.

I'm afraid I don't know enough about your data to tell you how you should combine the values to get a single line of data for all 38 years.
