+ <h2>Methods</h2>
+
+ <a name="getbar"></a>
+ <b>obj.getBar()</b><br /><br />
+ This method makes it easier to get hold of which bar has been clicked on, or hovered over. It returns an array of:
+ <ul>
+ <li>The X coordinate</li>
+ <li>The Y coordinate</li>
+ <li>The width of the bar</li>
+ <li>The height of the bar</li>
+ <li>The numerical index of the bar. This corresponds (for example) to the tooltips array, and the coordinates array</li>
+ </ul>
+
+ An example usage is:
+
+ <pre class="code">
+&lt;canvas id="cvs" width="600" height="250"&gt;[No canvas support]&lt;/canvas&gt;
+
+&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
+&lt;script src="RGraph.hbar.js"&gt;&lt;/script&gt;
+
+&lt;script&gt;
+ myGraph = new RGraph.HBar('myCanvas', [1.2, 1.3, 1.4, 1.5,6,1.9,2,2.1,2.5]);
+ myGraph.Set('chart.labels', ['John', 'Barry', 'Rich', 'Craig', 'Tom', 'Frank', 'Helen', 'Joyce', 'Fred'])
+ myGraph.Draw();

+ context.strokeStyle = 'black';
+ context.fillStyle = 'rgba(255,255,255,0.5)';
+ context.strokeRect(top, left, width, height);
+ context.fillRect(top, left, width, height);
+ context.stroke();
+ context.fill();
+ }
+ }
