How to manually define color bar scale in seaborn heatmap

[SriRajesh]

Hi,

I want to define color bar, how to define manually.
I use below example:

import numpy as np; np.random.seed(0)
import seaborn as sns; sns.set()
uniform_data = np.random.rand(10, 12)
ax = sns.heatmap(uniform_data)

The automatic color bar ticks getting here are 0.2,0.4,0.6,0.8, but I want to display 0.0,0.2,0.4,0.6,0.8,1.0. How to make this.
