Question

Using matplotlib, I define the following function to print labels. Labels are located at the right place, but label is not correct.

def printPointLabel(x,y,z,iternum,ax):
    print x 
    label = '(%d, %d), ITER%s' % (x, y, iternum)
    ax.text(x, y, z, label)

I call printPointLabel for four different points in the for loop

for i,num,c in zip((0,sampl4,2*sampl4,len(simplexpath)-1),(0,sampl4,2*sampl4,len(simplexpath)),('r','r','g','b')):
    appendSimplex(xs,ys,zs,col,simplexpath[i], peaks, c)
    printPointLabel(simplexpath[i][0][0],simplexpath[i][0][1],peaks([simplexpath[i]  [0][0],simplexpath[i][0][1]]),num,ax)

and label content is not updated at each loop. It remains identical to first label.

Could you help?

Thanks!

There’s a problem with the

ax.text(x, y, z, label)

call. the text function’s call signature is:

text(x, y, s, fontdict=None, **kwargs)
