Python Plot, delete just the Label from the Legend
<p>I just want to delete the Label from the Legend: </p>

<p>example (i just copy pasted the plot from an other stackoverflow problem)<a href="https://stackoverflow.com/questions/4700614/how-to-put-the-legend-out-of-the-plot">Plot example</a></p>

<p><a href="https://i.stack.imgur.com/ntD7R.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ntD7R.jpg" alt="enter image description here"></a></p>

<p>The question is, is there a way to delete the color Labels in the legend?</p>

<p>So that I'll just see "first" , "second" , "third" without the blue,green,red color label.</p>

<p>My problem is, i just want to use 1 Value in the Legend ( float ) and i dont want to have a label. 
The Value should be outside of the plot like in this example.
I use the Legend with this code:</p>

<pre><code>PC= np.pearsonr(x,y)
plt.scatter(x,y,color="#3F5D7D",label='PK:  %.3f'%(PC[0]))
plt.legend(prop={'size':12},bbox_to_anchor=(1.1, 1.1))
</code></pre>
