S-PLUS Graphlets™ Gallery

This graphlet includes two pages with different displays of intra-day trades in crude light oil futures.

The first page shows a standard High-Low Time Series chart. There are two hyperlinks within the chart; these link to (fictitious) news stories that occurred at the marked times.

The second page shows a custom-built Point and Figure chart.  This kind of chart is a popular tool for futures traders. Click on the Point&Figure tab on the graphlet to see it.
