Example
The following example
shows a bar chart of the top global automobile makers in 2008. To
focus the graph on the 2008 merger between Chrysler and Fiat, the
example uses DRAWRECTANGLE and DRAWIMAGE statements to highlight the
three bars in the chart that correspond to the unit sales for the
two auto makers. The example also uses a DRAWARROW statement and two
BEGINPOLYLINE blocks to point to the sales figures, and it uses a
DRAWTEXT statement to explain the implications of the merger.
All of the draw statements
in this example use the data space (see About the Drawing Space and Drawing Units) to integrate the drawn elements into the
graph’s data area.
