Open Flash Chart

:: Home - Gallery - Data

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 - Data

Add different data to the graph.

The chart will automatically resize all of the elements to fit the large key.

Method: set_data()

set_data( array $data )

Method: line()

line( int $line_width, string $colour, string $key_text[, int $size] )

Draws a line. This does not have tool tips. This is a bug, and at the moment I'm not sure if it needs fixing.

Method: line_dot()

line_dot( int $line_width, int $dot_size, string $colour, string $key_text[, int $key_size] )

Method: line_hollow()

line_hollow( int $line_width, int $circle_size, string $colour, string $key_text[, int $key_size] )

To add more than one line of data to the graph, call the method set_data() with each line of data. Then set the line style with line()

For details of how we changed the key text styles, see Line and Key.
