Specifies the lowest value displayed from all data series as the smallest data value on a given axis.

void object->SetAxisMinValue( int axis_number, min_value )

Arguments

object

Required. A Chart object.

axis_number

Required. An integer value that specifies the axis (see table below).

min_value

Required. A data value that specifies the lowest value on the selected axis.

Remarks

The SetAxisMinValue method specifies the lowest value displayed from all data series as the smallest data value on a given axis.

The axis is defined by an integer value interpreted as follows:

Code	Definition
0	Horizontal Axis
1	Vertical Axis
2	Secondary Horizontal Axis
3	Secondary Vertical Axis

Use the ResetAxisBounds method to let Swiff Chart Generator automatically determine the Axis Min value.

PHP Sample Code

The following PHP code illustrates use of the SetAxisMinValue method in a PHP page.

// Load the style file first!
$chart->LoadStyle( "C:\\myXYStyle.scs" );

$chart->SetSeriesXValuesFromString( 0, "02/2007;05/2007;12/2007" );
$chart->SetSeriesYValuesFromString( 0, "187.8;156.9;121.8" );

// Set the min-max displayed dates of the X axis
$chart->SetAxisMinValue( 0, "12/2006" );
$chart->SetAxisMaxValue( 0, "07/2008" );

// Set the min-max displayed values of the Y axis
$chart->SetAxisMinValue( 1, 110 );
$chart->SetAxisMaxValue( 1, 200 );

// X axis and Y axis cross at (05/2007,110)
$chart->SetAxisCrossValue( 0, "05/2007" );
$chart->SetAxisCrossValue( 1, 110 );

$chart->ExportAsResponse();
