I am trying to modify the 2D contour figure automatically generated by ksdensity for my bi-variate data.
I used the following lines, where ``data`` is a matrix size of 16000-by-2:
I used ``gcf``, ``gca``, ``findobj`` to extract the current figure, axis, object, however, I couldn't modify any of the properties I need. For example, setting it to a filled contour ('fill', 'on'), turning off the lines ('Linestyle','none') and increasing the level.
Does anyone know how to do this? Thanks!
