With the defaut true value, the only * the fonts of the yAxis will be used. * @property bool $axisEndStyle * Style of axis end markers. Defauls to arrow heads, but you may * also use all symbol constants defined ein the ezcGraph class, * especially ezcGraph::NO_SYMBOL. * @property bool $shortAxis * Defines wheather to render the axis extending the chart boundings * or stop them at the chart boundings.
