<font size="2" face="Arial">This chart image can be placed freely in your page
and treated as a regular image file:<br>

The legend below is a separate image file which can be independently placed in
the page.<br><br></font>

<td><font size="2" face="Arial">This feature is useful for custom layouts but it
is also a powerful addition for multiple chart alignment as chart width is not
affected by differing legend size requirements on the chart surface. In
this sample the legend is added to a table so this text can adjoin it.</font></td>
