Gallery - Format Numbers

Method: set_y_format

set_y_format( string $val )

Format the Y axis labels. If any of the following format options are used, the Y axis labels use the format options.

In the string, the magic #val# is replaced with the actual value (see tooltip for more details on magic string values). So in the example above the following Y Axis Format string was used:

#val# km

So #val# is replaced with the calculated Y Axis value.

Method: set_num_decimals

set_num_decimals( integer $val )

For example, we set this to 3, so now 6.6666666666 becomes 6.666 and 7.1 stays as 7.1

This effects the tooltips, the Y axis labels and the X axis labels in scatter charts.

Method: set_is_fixed_num_decimals_forced

set_is_fixed_num_decimals_forced( boolean $val )

If this is set to true the chart will display all calculated numbers with set_num_decimals() (see above) (e.g. for set_num_decimals(3), 10 becomes 10.000, 10.1 becomes 10.100) this is useful for prices: £10 becomes £10.00

This effects the tooltips, the Y axis labels and the X axis labels in scatter charts.

Method: set_is_decimal_separator_comma

set_is_decimal_separator_comma( boolean $val )

Use a comma for the decimal seperator.

This effects the tooltips, the Y axis labels and the X axis labels in scatter charts.

Method: set_is_thousand_separator_disabled

set_is_thousand_separator_disabled( boolean $val )

Stop using a comma to seperate the thousands.

This effects the tooltips, the Y axis labels and the X axis labels in scatter charts.
