Stacked bar chart of Tesla's revenue, expenses, profit and stock price for 2012-2015

Tesla's Revenue and Profit Growth

Tesla's revenue grew tenfold between 2012 and 2015.  Its expenses, however, kept pace and it has not shown a profit.  Investors were undeterred.  Tesla's stock price grew from $34 at the end of 2012 to $240 at the end of 2015.  The data is summarized in the stacked bar chart below:


Adding a net line to a stacked bar chart allowed me to show revenue expenses and net profit in the same chart.  I used a legend to identify the three variables.  Bar totals contain the revenue and expense amounts for each year.  I added the values to the net lines to show net profits.  I also increased my bar gaps to widen the spaces between bars to make room for the net line values.  I added stock price as a data row and hid the Y axis.  Here is the chart in SlideShare to download and edit using Mekko Graphics:
