How can I do scatter density plot inmatlab?

I have two variables such as Blue_ELM and Blue_USGS each of size of 779963x1, I want to do the scatter density plot so that I can see where my most of data points lies? How can I do this?

See https://www.mathworks.com/matlabcentral/fileexchange/65166-densityplot-x-y-varargin and https://www.mathworks.com/matlabcentral/fileexchange/31726-data-density-plot and https://www.mathworks.com/matlabcentral/answers/225934-using-matlab-to-plot-density-contour-for-scatter-plot#answer_184607

If you have Mapping Toolbox then geodensityplot

Dear Walter,

Non of these are working. Would you please suggest me any other technique?

[Walter Roberson]

No, if you are having trouble installing Add-Ons, and problems calling accumarray() then we need to debug those problems first before we hope to make progress on your task at hand. If none of the approaches I posted the links to work, then you have serious problems with your MATLAB installation.

What about simply using scatter :

scatter(Blue_ELM , Blue_USGS)
xlabel('Blue_ELM')
ylabel('Blue_USGS')
