Seaborn Heatmap Colorbar Label as Percentage : <p>Given this heat map:</p>

<pre><code>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)
</code></pre>

<p>How would I go about making the color bar values display in percent format?
Also, what if I just wanted to show the first and last values on the color bar?</p>

<p>Thanks in advance!</p>
