Unsure how to plot the various columns from my data-set. Using df.scatter or plt.plot(kind = 'scatter'...) throws "Line2D object has no property kind error", so I've been using plt.plot(df['colname'], df['colname'], 'o').

Each data point has the following information:

* Date (datetime.date)
* Number of Businesses (integer)
* Big/Small (String of "B" or "S")
* Size (Number of either 1000 or something less than 1000)

I want to create a scatterplot that plots (x = date, y = number of businesses) while marking/coloring each data point by whether its Big/Small and whether it's Size = 1000 or is less than 1000. Not sure how to do this because errors keep being thrown (on my part I need to also weed out the N.A.s)
