Reading and visualizing netcdf with vectors of differing lengths

This is my first time reading netcdf data. I can read the file and variables of interest as follows:
vardata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','TLdata');
H_latdata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','H_latdata');
H_londata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','H_londata');
H_freqdata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','H_freqdata');
Unfortunately I cannot attach the file because even in Zip format it is greater than 5mb.
>> whos vardata
Name Size Bytes Class Attributes
vardata 91x489x280 49838880 single
I'd like to be able to plot/visualize the data, but when I try to use plot3() it tells me the vectors must be the same length. Is there another way?
My goal is to find the freq value for a specific lat/lon, but in order to do make a selection of positions of interest, I need to look at the positions I have and see how they vary.

If you want to attach the file, you can upload in some cloud spaces (google drive) and share the link here without asking the login's credentials.
[p,m,n] = size(vardata) ;
for i = 1:p
pcolor(H_londata,H_latdata,squeeze(vardata(i,:,:))') ;
shading interp
drawnow
end
If you want to extract a series from the (i,j) position
i = 3 ;
j = 4 ;
v = squeeze(vardata(:,j,i)) ;
plot(v)

Done :) Thank you!
They are in UTM so a coordinate format just different to decimal degrees. I will try your suggestion, thank you.
