Open Flash Chart

:: Home - Gallery - X Offset

Info: Open Flash Chart 2 is out. Version 1.x and these pages will never disappear and the charts will continue working forever, but further development on 1.x has stopped. Take a look at version 2 here Open Flash Chart 2.

Gallery - X Offset

Method: set_x_offset

set_x_offset( boolean $val )

By default this is set to true, setting it to false shifts the X axis flush to the Y Axis.

Doing this is for bar charts makes them fall off the edge of the chart, so they look and act a bit weird.

See the scatter chart for another example.
