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 )
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 |
Note: Loading chart graphical settings from a style file via the method LoadStyle automatically overrides all the Axis Min values. Therefore, you must call the LoadStyle method before calling the SetAxisMinValue method.
Use the ResetAxisBounds method to let Swiff Chart Generator automatically determine the Axis Min value.
The following PHP code illustrates use of the SetAxisMinValue method in a PHP page.
//Load the syle file first! $chart->LoadStyle( "C:\myXYStyle.scs" ); $chart->SetSeparators( ";", true ); $chart->AddSeries(); $chart->SetSeriesXValuesFromString( 0, "02/2002;05/2002;12/2002" ); $chart->SetSeriesYValuesFromString( 0, "187.8;156.9;121.8" ); //Set the min-max displayed dates of the X axis $chart->SetAxisMinValue( 0, "12/2001" ); $chart->SetAxisMaxValue( 0, "02/2003" ); //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 (12/1999,110) $chart->SetAxisCrossValue( 0, "12/2001" ); $chart->SetAxisCrossValue( 1, 110 ); $chart->ExportAsResponse();
