## Chart3d  

Python package to create from a numpy Array a 3d triangle Chart like 

https://skfb.ly/osJAz

```{python}

import chart3d as c3d

from chart3d import EnumColor

_date=datetime.now()-timedelta(366)

pointMatrix = None

for x in range(366):

    ay = np.array(_date)

    for y in range(25):

        ay=np.append(ay,random()*15+3)

    if pointMatrix is None:

        pointMatrix=np.array([ay])

    else:

        pointMatrix=np.append(pointMatrix,[ay],axis=0)

    _date = _date + timedelta(1)

pointMatrix2 = np.array([[datetime.now()-timedelta(-2),1, 2, 3, 4, 5, 6, 7, 8, 9],

                        [datetime.now()-timedelta(-1),5, 5, 5, 5, 5, 5, 5, 5, 5],

                        [datetime.now()-timedelta(-0),9, 8, 7, 6, 5, 4, 3, 2, 1]])

vertices, vcolors, triangles = c3d.matrix_to_vertices_quader(pointMatrix,

                                                             colx=EnumColor.r2b,
