This renderer uses a separate rendering engine to draw the text on the canvas. Two modes of rendering the text are available. If the browser has native font support for canvas fonts (currently Mozila 3.5 and Safari 4), you can enable text rendering with the canvas fillText method. You do so by setting the “enableFontSupport” option to true.</p><p>Browsers lacking native font support will have the text drawn on the canvas using the Hershey font metrics. Even if the “enableFontSupport” option is true non-supporting browsers will still render with the Hershey font.</p><!--START_ND_SUMMARY--><divclass=Summary><divclass=STitle>Summary</div><divclass=SBorder><tableborder=0cellspacing=0cellpadding=0class=STable><trclass="SMain"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer">$.jqplot.<wbr>CanvasAxisLabelRenderer</a></td><tdclass=SDescription>Renderer to draw axis labels with a canvas element to support advanced featrues such as rotated text. </td></tr><trclass="SGroup SIndent1"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.Properties">Properties</a></td><tdclass=SDescription></td></tr><trclass="SProperty SIndent2 SMarked"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.angle"id=link1onMouseOver="ShowTip(event, 'tt1', 'link1')"onMouseOut="HideTip('tt1')">angle</a></td><tdclass=SDescription>angle of text, measured clockwise from x axis.</td></tr><trclass="SProperty SIndent2"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.show"id=link2onMouseOver="ShowTip(event, 'tt2', 'link2')"onMouseOut="HideTip('tt2')">show</a></td><tdclass=SDescription>whether or not to show the tick (mark and label).</td></tr><trclass="SProperty SIndent2 SMarked"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.showLabel"id=link3onMouseOver="ShowTip(event, 'tt3', 'link3')"onMouseOut="HideTip('tt3')">showLabel</a></td><tdclass=SDescription>whether or not to show the label.</td></tr><trclass="SProperty SIndent2"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.label"id=link4onMouseOver="ShowTip(event, 'tt4', 'link4')"onMouseOut="HideTip('tt4')">label</a></td><tdclass=SDescription>label for the axis.</td></tr><trclass="SProperty SIndent2 SMarked"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.fontFamily"id=link5onMouseOver="ShowTip(event, 'tt5', 'link5')"onMouseOut="HideTip('tt5')">fontFamily</a></td><tdclass=SDescription>CSS spec for the font-family css attribute. </td></tr><trclass="SProperty SIndent2"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.fontSize"id=link6onMouseOver="ShowTip(event, 'tt6', 'link6')"onMouseOut="HideTip('tt6')">fontSize</a></td><tdclass=SDescription>CSS spec for font size.</td></tr><trclass="SProperty SIndent2 SMarked"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.fontWeight"id=link7onMouseOver="ShowTip(event, 'tt7', 'link7')"onMouseOut="HideTip('tt7')">fontWeight</a></td><tdclass=SDescription></td></tr><trclass="SProperty SIndent2"><tdclass=SEntry><ahref="#$.jqplot.CanvasAxisLabelRenderer.fontStretch"id=link8onMouseOver="ShowTip(event, 'tt8', 'link8')"onMouseOut="HideTip('tt8')">fontStretch</a></td><tdclass=SDescription>Multiplier to condense or expand font width. </
