Class usage and Overview
Internal class that handles the drawing and formatting of the tick marks on each axis. This class is accessed through it'sinstance variable in the scale, e.g.

$graph->xaxis->scale->ticks->Set(20,10);

Note: When you manually specify a scale you must also specify the major/minor tick intervall.

Class Methods

 

 

function AdjustForDST($aFlg)
// For a normal linear type of scale the major ticks will always be multiples// of the minor ticks. In order to avoid any rounding issues the major ticks are// defined as every "step" minor ticks and not calculated separately

ArgumentDefaultDescription
$aFlg true No description available

Description
No description available.

 

 

function GetMajor()
Return major step size in world coordinates


Description
Return major step size in world coordinates 

Example

$majintervall = $graph->xaxis->scale->ticks->Getmajor();

 

 

function GetMinor()
// Return minor step size in world coordinates


Description
Return minor step size in world coordinates. 

Example

$majintervall = $graph->xaxis->scale->ticks->Getmajor();

 

 

function Set($aMajStep,$aMinStep)
// Set Minor and Major ticks (in world coordinates)

ArgumentDefaultDescription
$aMajStep  Distance between major tick marks
$aMinStep false Distance between minor tick marks

Description
Set Minor and Major tick intervall (in world coordinates) 

Example

$graph->yaxis->scale->ticks->Set(40,20);

 

 

function SetMajTickPositions($aMajPos,$aLabels)
//(" Minor or major step size is 0. Check that you haven't got an accidental SetTextTicks(0) in your code. If this is not the case you might have stumbled upon a bug in JpGraph. Please report this and if possible include the data that caused the problem."

ArgumentDefaultDescription
$aMajPos  No description available
$aLabels NULL No description available

Description
No description available.

 

 

function SetTextLabelStart($aTextLabelOff)
Which tick label should we start with?

ArgumentDefaultDescription
$aTextLabelOff  The number thaht the automatic textscale should start with.

Description
Normally text labels start at 0. However, automtic text labels can be started with an arbitrary number as specified with the argument to this method.  

Example

$graph->xaxis->scale->ticks->SetTextLabelStart(10);

 

 

function SetTickPositions($aMajPos,$aMinPos,$aLabels)
Manually specify tick positions for the axis

ArgumentDefaultDescription
$aMajPos  Array of major positions
$aMinPos NULL Array of minor positions
$aLabels NULL Array of major label strings

Description
Manually specify major and minor tick positions for the axis together with the optional label strings. If no label array is specified then the numerical values at the positions of the major tick marks will be used as label strings. 

Example

$graph->xaxis->SetMajTickPositions($tickPositions,$tickLabels);
