Looking at how you are setting x and y_a1:</div><div> y_a1 = dim_avg_n_Wrap(dox_ave_a1,(/1,2/)) <br></div><div>x = (/1/)<br></div><div><br></div><div>NCL returned a list of error messages to you, but the most important one is the first one:</div><div>fatal:CheckArray:Each vector in the caXArray array must have at least 2 elements<br></div><div><br></div><div>Your x array has one element. Assyming y_a1 is a 1D array containing values at each timestep, your input array "x" should contain the times that you want to plot the timeseries against. A typical example of using gsn_csm_xy on an annual timeseries that runs from 1900-2017:</div><div>plot = gsn_csm_xy(wks,ispan(1900,2017,1),tseries,res)</div><div><br></div><div>Hope that helps.
