Class: ezcGraphChartElementLabeledAxis  - X-Ref

Class to represent a labeled axis.

Axis elements represent the axis in a bar, line or radar chart. They are
chart elements (ezcGraphChartElement) extending from
ezcGraphChartElementAxis, where additional formatting options can be found.
You should generally use the axis, which matches your input data best, so
that the automatic chart layouting works best. Aavailable axis types are:

- ezcGraphChartElementDateAxis
- ezcGraphChartElementLabeledAxis
- ezcGraphChartElementLogarithmicalAxis
- ezcGraphChartElementNumericAxis

The labeled axis will accept any values and converts them to strings. The
labeled axis does not know about any special meanings of values and
maintains the order of the given labels with equidistant spaces between all
values. If your data has a special meaning, like a set of numbers or dates,
use one of the other more appropriate axis.

Because it is not always possible to fit all labels in a chart you may
define the count of labels drawn using the $labelCount option. For all other
labels only a small step will be rendered.

The labeled axis may be used like:

<code>
$graph = new ezcGraphLineChart();
$graph->options->fillLines = 210;
$graph->options->font->maxFontSize = 10;
$graph->title = 'Error level colors';
$graph->legend = false;

$graph->yAxis = new ezcGraphChartElementLabeledAxis();
$graph->yAxis->axisLabelRenderer->showZeroValue = true;

$graph->yAxis->label = 'Color';
$graph->xAxis->label = 'Error level';

// Add data
$graph->data['colors'] = new ezcGraphArrayDataSet(
array(
'info' => 'blue',
'notice' => 'green',
'warning' => 'orange',
'error' => 'red',
'fatal' => 'red',
)
);

$graph->render( 400, 150, 'tutorial_axis_labeled.svg' );
