<div dir="ltr">Hi Prasad,<div>Please do not write to individuals who respond to ncl-talk and not to ncl-talk itself, as that way others can assist and see the resolution of the issue. My original email still stands: The range of values specified in tmXBValues needs to match the range of x-axis coordinate values of the plotted array. In your case, from your printVarSummary output, you have latitudes that are around 30N:</div><div>lat: [29.84782..33.84531]<br></div><div>so you will want to set tmXBValues to have values between 29.84 and 33.84.

Try commenting out the resources that start with res@tmXB*, and labels should appear (although they likely will not be what you want).
