title: How do I plot this as a scatterplot?
body: <p>This is killing me.
  How do I modify this code so that the chart displays as a scatterplot instead of a line graph? I think it has something to do with this line but I dont know what ax=ax does.</p>
  
  <pre><code>data.plot(ax=ax)
  </code></pre>
  
  <p>Here is my code:</p>
  
  <pre><code>#import libraries
  import pandas as pd
  import matplotlib.pyplot as plt
  import matplotlib.dates as mdates
  %matplotlib inline
  from matplotlib.dates import MO, TU, WE, TH, FR, SA, SU
  
  #read data from csv selecting columns inline
  data = pd.read_csv('EURCHF_Daily.csv', skipinitialspace=True,parse_dates=['Date'])
  #set date as index
  data.set_index('Date',inplace=True)
  data = data.loc['2019/11/5':'2019/12/30']
  #data = data[['Open','High','Low','Last']]
  #data['High_Low_Mean'] = data['High'] - data['Low']
  data = data[['Last']]
  
  #plot data
  fig, ax = plt.subplots(figsize=(15,7))
  data.plot(ax=ax)
  ax.tick_params(axis='x', colors='White',rotation=90)
  ax.tick_params(axis='y', colors='White')
  plt.style.use('seaborn-paper')
  
  #set ticks every week
  ax.xaxis.set_major_locator(mdates.WeekdayLocator(byweekday=(MO, TU, WE, TH, FR,)))
  #set major ticks format
  ax.xaxis.set_major_formatter(mdates.DateFormatter('%b %d'))
  </code></pre>
