<div class="textblock"><p>Class which represents an axis of a cartesian chart. </p>
<p>A cartesian chart has two or three axes: an X axis (<a class="el" href="group__charts.html#ggaddb678f67fbd9f374fcee0922f158c9fa2a592919e6cbd94bf09e1259559499b5">XAxis</a>), a Y axis (<a class="el" href="group__charts.html#ggaddb678f67fbd9f374fcee0922f158c9fa2e1017fdef77b4663715c3d7663a4db4">YAxis</a>) and optionally a second Y axis (<a class="el" href="group__charts.html#ggaddb678f67fbd9f374fcee0922f158c9fadbfcf55c246aa3a385974a185f4220e3">Y2Axis</a>). Each of the up to three axes in a cartesian chart has a unique <a class="el" href="classWt_1_1Chart_1_1WAxis.html#aca500256c7ec397512f872bd44e93b8d" title="Returns the axis id.">id()</a> that identifies which of these three axes it is in the enclosing <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a726d6c73a28960ed0231ea4ed57e5be9" title="Returns the chart to which this axis belongs.">chart()</a>.</p>
<p>Use <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a59fd4c6a79f6e3ea75f21aa44c4acfa8" title="Sets whether this axis is visible.">setVisible(bool)</a> to change the visibility of an axis, <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a79d70190d984c7f956e44b79de0af527" title="Sets whether gridlines are displayed for this axis.">setGridLinesEnabled(bool)</a> to show grid lines for an axis. The pen styles for rendering the axis or grid lines may be changed using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#ab1b9dcb9e23e01ec18994712fa5e11d1" title="Changes the pen used for rendering the axis and ticks.">setPen()</a> and <a class="el" href="classWt_1_1Chart_1_1WAxis.html#aa97db5c1f1bff788382ef48b8a6d1cc2" title="Changes the pen used for rendering the grid lines.">setGridLinesPen()</a>. A margin between the axis and the main plot area may be configured using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a61a297a8d3c99e74b07e9def9ebe88a5" title="Sets the margin between the axis and the plot area.">setMargin()</a>.</p>
<p>By default, the axis will automatically adjust its range so that all data will be visible. You may manually specify a range using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a878e20a87f7f6c5b4693bb81699c9f5b" title="Sets the minimum value displayed on the axis.">setMinimum()</a>, setMaximum or <a class="el" href="classWt_1_1Chart_1_1WAxis.html#aae563fd94b81a03cfe2662dbde2ae548" title="Sets the axis range (minimum and maximum values) manually.">setRange()</a>. The interval between labels is by default automatically adjusted depending on the axis length and the range, but may be manually specified using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a68b1f798fd0d9a713fac29f9d761e2a8" title="Sets the label interval.">setLabelInterval()</a>.</p>
<p>The axis has support for being "broken", to support displaying data with a few outliers which would otherwise swamp the chart. This is not done automatically, but instead you need to use <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a159f74342b4800e5c5be11eb1b2a351b" title="Specify a range that needs to be omitted from the axis.">setBreak()</a> to specify the value range that needs to be omitted from the axis. The omission is rendered in the axis and in bars that cross the break.</p>
<p>The labels are shown using a "%.4g" format string for numbers, and "dd/MM/yyyy" (for <a class="el" href="group__charts.html#ggadfcaed8cd6ff52f5747f7df48f2eeab6aaa627030efa552170a889d7a80a65a12">DateScale</a>). The format may be customized using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#a7c37c241825af404b36916dcae9ae87b" title="Sets the label format.">setLabelFormat()</a>. The angle of the label text may be changed using <a class="el" href="classWt_1_1Chart_1_1WAxis.html#afd850eefc2beb7dffa5a637987cb1c6c" title="Sets the label angle.">setLabelAngle(double)</a>. By default, all labels are printed horizontally.</p>
