<div class="textblock"><p>A cartesian chart. </p>
<p>A cartesian chart is a chart that uses X and Y axes. It can display one or multiple data series, which each may be rendered using bars, lines, areas, or points.</p>
<p>To use a cartesian chart, the minimum you need to do is set a model using <a class="el" href="classWt_1_1Chart_1_1WAbstractChart.html#aa23d116689e939301470398df8ad5c8b" title="Set the model.">setModel()</a>, set the model column that holds the X data using <a class="el" href="classWt_1_1Chart_1_1WCartesianChart.html#a6c954fa4ed6d73f00ee973bfe3af5ed0" title="Sets the the model column for the X series.">setXSeriesColumn(int modelColumn)</a>, and add one or more series using <a class="el" href="classWt_1_1Chart_1_1WCartesianChart.html#afa4ac6588e6e2e0dd93320c3a0541d46" title="Adds a data series.">addSeries(const WDataSeries&)</a>. Each series corresponds to one data column that holds Y data.</p>
<p>A cartesian chart is either a <a class="el" href="group__charts.html#gga8d63464f873580c77508e1c0c26cbfeaaebfd9bd11d1126f2db7ff891c04c29f9">CategoryChart</a> or a <a class="el" href="group__charts.html#gga8d63464f873580c77508e1c0c26cbfeaa6ddab43d32242eb28831938a1e469a1f">ScatterPlot</a>.</p>
<p>In a <b>CategoryChart</b>, the X series represent different categories, which are listed consecutively in model row order. The X axis scale is set to <a class="el" href="group__charts.html#ggadfcaed8cd6ff52f5747f7df48f2eeab6aa9b1356757a7b0935c3302c32798ef14">CategoryScale</a>.</p>
<div class="image">
<img src="ChartWCartesianChart-1.png" alt="ChartWCartesianChart-1.png"/>
<div class="caption">
A category chart with bar series</div></div>
<p> Each series may be rendered differently, and this is configured in the data series (see <a class="el" href="classWt_1_1Chart_1_1WDataSeries.html" title="A single data series in a cartesian chart.">WDataSeries</a> for more information).</p>
<p>In a <b>ScatterPlot</b>, the X series data are interpreted as numbers on a numerical scale. The scale for the X axis defaults to a <a class="el" href="group__charts.html#ggadfcaed8cd6ff52f5747f7df48f2eeab6ad1c254fd10596e2565b32fd6f5967094">LinearScale</a>, but this may be changed to a <a class="el" href="group__charts.html#ggadfcaed8cd6ff52f5747f7df48f2eeab6aaa627030efa552170a889d7a80a65a12">DateScale</a> when the X series contains dates (of type <a class="el" href="classWt_1_1WDate.html" title="A value class that represents a date on the Gregorian calendar.">WDate</a>) to create a time series chart, or to a <a class="el" href="group__charts.html#ggadfcaed8cd6ff52f5747f7df48f2eeab6afba90921c9efb6c5131cdb1590bfa406">LogScale</a>. A ScatterPlot supports the same types of data series as a CategoryChart, but does not support stacking. In a scatter plot, the X series do not need to be ordered in increasing values, and may be set differently for each dataseries using <a class="el" href="classWt_1_1Chart_1_1WDataSeries.html#a9361e12e94699f59090ae8ac3a4921df" title="Sets the X series column.">WDataSeries::setXSeriesColumn(int modelColumn)</a>.</p>

<div class="caption">
A time series scatter plot with line series</div></div>
<p> Missing data in a model series Y values is interpreted as a <em>break</em>. For curve-like series, this breaks the curve (or line).</p>
<p>The cartesian chart has support for dual Y axes. Each data series may be bound to one of the two Y axes. By default, only the first Y axis is displayed. To show the second Y axis you will need to call:</p>

</pre></div><p>By default a chart has a horizontal X axis and a vertical Y axis, which corresponds to a <a class="el" href="namespaceWt.html#a2a8d45559e16a0185bf61bfad0a67912af916b7ec24727db2d972f0770170c7f5">Vertical</a> orientation.

<p>The styling of the series data are dictated by a palette which may be set using <a class="el" href="classWt_1_1Chart_1_1WAbstractChart.html#a044936e6358c8efc55699effc4b946d8" title="Set a palette for the chart.">setPalette(WChartPalette *)</a>, but may be overridden by settings in each data series.</p>
