how to draw 2D or 3D graphs with large data
조회 수: 3(최근 30일)
I have a data that contains X and Y coordinates (almost 25000 each), I also have Z values from an experiments. I would like to draw a 3D graph or 2D that can plot X and Y coordinates while Z coresponds to the height/density or just color at each X and Y values. I have tried to reduce my data to 400 and used the below
view ([0 90])
However, the figure wasn't understandable and it was showing a square unlike the real data even when I use only the 400 it suppose to be like a (+) not square.
I have also tried the meshgrid for X and Y and repmat for Z but the result was almost the same.
I'm looking for something simillar to the attached figure.
Is there anyway that I can do that knowing that all my data are known (no equations or assumptions needed)
