visualization - Plot 3D Grid Data as Heat Map using gnuplot -

-

assume have 5x4x3 3d grid, each cell has value:

0.5523    0.0495    0.1465    0.5386 0.6299    0.4896    0.1891    0.6952 0.0320    0.1925    0.0427    0.4991 0.6147    0.1231    0.6352    0.5358 0.3624    0.2055    0.2819    0.4452  0.1239    0.2085    0.9479    0.6210 0.4904    0.5650    0.0821    0.5737 0.8530    0.6403    0.1057    0.0521 0.8739    0.4170    0.1420    0.9312 0.2703    0.2060    0.1665    0.7287  0.7378    0.8589    0.1339    0.3329 0.0634    0.7856    0.0309    0.4671 0.8604    0.5134    0.9391    0.6482 0.9344    0.1776    0.3013    0.0252 0.9844    0.3986    0.2955    0.8422

how can achieve plot in gnuplot similar plot achieved in matlab using patch? note grid cells has alpha value of 0.8. enter image description here
