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

LinearTicks ::
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

Argument Default Description

$aFlg true No description available

Argument	Default	Description
$aFlg	true	No description available

Description:

No description available.

LinearTicks ::
GetMajor()

Return major step size in world coordinates

Description:

Return major step size in world coordinates

Example:

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

LinearTicks ::
GetMinor()

// Return minor step size in world coordinates

Description:

Return minor step size in world coordinates.

Example:

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

LinearTicks ::
Set($aMajStep, $aMinStep)

// Set Minor and Major ticks (in world coordinates)

Argument Default Description

$aMajStep Distance between major tick marks

$aMinStep false Distance between minor tick marks

Argument	Default	Description
$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);

LinearTicks ::
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."

Argument Default Description

$aMajPos No description available

$aLabels NULL No description available

Argument	Default	Description
$aMajPos		No description available
$aLabels	NULL	No description available

Description:

No description available.

LinearTicks ::
SetTextLabelStart($aTextLabelOff)

Which tick label should we start with?

Argument Default Description

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

Argument	Default	Description
$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);

LinearTicks ::
SetTickPositions($aMajPos, $aMinPos, $aLabels)

Manually specify tick positions for the axis

Argument Default Description

$aMajPos Array of major positions

$aMinPos NULL Array of minor positions

$aLabels NULL Array of major label strings

Argument	Default	Description
$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);
