Plot the "microsoft" series in data and add the title "Dividend date and amount"
Without creating a new plot, add the "citigroup" series to the plot, and make its line "orange" and twice as thick as the default width
Add an appropriately scaled Y axis on the right side of the chart for the "citigroup" data using axis() and pretty(), and make it orange
