title: Converting values with commas in a pandas dataframe to floats.
body: <p>I have been trying to convert values with commas in a pandas dataframe to floats with little success. I also tried .replace(",","") but it doesn't work? How can I go about changing the Close_y column to float and the Date column to date values so that I can plot them? Any help would be appreciated. <a href="https://i.stack.imgur.com/IRJx2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IRJx2.png" alt="This is what I&#39;ve tried"></a></p>
