3d plot for big array

[reptile Forex]

Hello,

I found this forum regarding Luke sugestion around some question about 3d plot for big array (how to).

I'm not understand main problem for this type ploting (manipulate axes). Can You explain me how this should be in python code?

Some csv files are here https://drive.google.com/file/d/0B90uvLHLyJO1V1pTV1I3OVpwS2M/view?usp=sharing

The code is based on example  w.setWindowTitle('pyqtgraph example: GLLinePlotItem')

code: matrix8.py

---

from pyqtgraph.Qt import QtCore, QtGui
import pyqtgraph.opengl as gl
import pyqtgraph as pg
import numpy as np

 

app = QtGui.QApplication.instance()
if app == None:
    app = QtGui.QApplication([])

 

w = gl.GLViewWidget()
w.opts['distance'] = 40
w.show()
w.setWindowTitle('3D PLOT')

 

gx = gl.GLGridItem()
gx.rotate(90, 0, 1, 0)
gx.translate(-10, 0, 0)
w.addItem(gx)
gy = gl.GLGridItem()
gy.rotate(90, 1, 0, 0)
gy.translate(0, -10, 0)
w.addItem(gy)
gz = gl.GLGridItem()
gz.translate(0, 0, -10)
w.addItem(gz)

 

file = 'E:\DB\matrix8.csv';
my_data = np.loadtxt(file,delimiter=';',skiprows=1)
X = my_data[0,:]
Y = my_data[1,:]
Z = my_data[1,:]

 

n = 7
y = np.linspace(-10,10,n)
x = np.linspace(-10,10,100)
for i in range(n):

 

    yi = X
    d = Y
    z = Z
    pts = np.vstack([X,Y,Z]).transpose()
    #pts = np.array([X,Y,Z]).transpose()

 

    #yi = np.array([y[i]]*100)
    #d = (x**22 + yi**2)**0.5
    #z = 10 * np.cos(d) / (d+1)
    #pts = np.vstack([x,yi,z]).transpose()

 

    plt = gl.GLLinePlotItem(pos=pts, color=pg.glColor((i,n*1.3)), width=(i+1)/10., antialias=True)
    w.addItem(plt)

 

## Start Qt event loop unless running in interactive mode.
if __name__ == '__main__':
    import sys
    if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
        QtGui.QApplication.instance().exec_()

This ploting just line not surface how I expect (attachment).

You are using the example "LinePlot", why would you expect it to make a surface?  You should try "GLSurfacePlot" example.

Thx for interesing in this topic. Well.. the surface in Mathematica ploting my matrix from file very long. The matrix is for small example 20000 x 500 or more. Soo.. my idea was.. forgot about surface and draw line from one row and any next row i next line. Thats why LinePlot looks more sense for me as GLSurfacePlot_3d.PNG
The surface is not to much cognitive for me.

In fact I think that this project must be droped based on Mathematica experience as long computing (around 15min as on colur surface and more for rainbow MATHEMATICA EU1.png ).
matrix10 v1.png - is as small test file as matrix.
