Solve the following python programming problem given the following code:
def _redraw(self, db, tofile = 0, eta = None) : 
    ' redraw the updated grid interactively ' 
    import pylab as p 
    if ((len (db) <= 3) or (not self.plotflag)) : 
        return 
nContours = 25 
    def cmp(x, y) : 
        if (x [0] < y [0]) : 
            return (- 1) 
if (x [0] > y [0]) : 
            return 1 
if (x [1] > y [1]) : 
            return (- 1) 
if (x [1] < y [1]) : 
            return 1 
return 0 
db.sort (cmp) 
    dbarr = p.asarray (db) 
    x = dbarr [:, 0] 
    dimy = len (x [(x == x [0])]) 
    dimx = (x.size / dimy) 
    print (('plotting: ', dimx, dimy)) 
    x = x.reshape (dimx, x) 
    y = dbarr [:, 1] 
    y = y.reshape (dimx, dimy) 
    z = dbarr [:, 2].reshape (dimx, dimy) 
    p.ioff () 
    p.clf () 
    p.contourf (x, y, z, nContours) 
    p.hsv ()

#Here is Python program to fix the buggy line: x = x.

x = x.reshape (dimx, dimy)
