 This renderer uses a separate rendering engine to draw the text on the canvas.&nbsp;  Two modes of rendering the text are available.&nbsp; 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.&nbsp; You do so by setting the &ldquo;enableFontSupport&rdquo; option to true.</p><p>Browsers lacking native font support will have the text drawn on the canvas using the Hershey font metrics.&nbsp;  Even if the &ldquo;enableFontSupport&rdquo; option is true non-supporting browsers will still render with the Hershey font.</p><!--START_ND_SUMMARY--><div class=Summary><div class=STitle>Summary</div><div class=SBorder><table border=0 cellspacing=0 cellpadding=0 class=STable><tr class="SMain"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer" >$.jqplot.<wbr>CanvasAxisLabelRenderer</a></td><td class=SDescription>Renderer to draw axis labels with a canvas element to support advanced featrues such as rotated text. </td></tr><tr class="SGroup SIndent1"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.Properties" >Properties</a></td><td class=SDescription></td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.angle" id=link1 onMouseOver="ShowTip(event, 'tt1', 'link1')" onMouseOut="HideTip('tt1')">angle</a></td><td class=SDescription>angle of text, measured clockwise from x axis.</td></tr><tr class="SProperty SIndent2"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.show" id=link2 onMouseOver="ShowTip(event, 'tt2', 'link2')" onMouseOut="HideTip('tt2')">show</a></td><td class=SDescription>wether or not to show the tick (mark and label).</td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.showLabel" id=link3 onMouseOver="ShowTip(event, 'tt3', 'link3')" onMouseOut="HideTip('tt3')">showLabel</a></td><td class=SDescription>wether or not to show the label.</td></tr><tr class="SProperty SIndent2"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.label" id=link4 onMouseOver="ShowTip(event, 'tt4', 'link4')" onMouseOut="HideTip('tt4')">label</a></td><td class=SDescription>label for the axis.</td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.fontFamily" id=link5 onMouseOver="ShowTip(event, 'tt5', 'link5')" onMouseOut="HideTip('tt5')">fontFamily</a></td><td class=SDescription>CSS spec for the font-family css attribute. </td></tr><tr class="SProperty SIndent2"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.fontSize" id=link6 onMouseOver="ShowTip(event, 'tt6', 'link6')" onMouseOut="HideTip('tt6')">fontSize</a></td><td class=SDescription>CSS spec for font size.</td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.fontWeight" id=link7 onMouseOver="ShowTip(event, 'tt7', 'link7')" onMouseOut="HideTip('tt7')">fontWeight</a></td><td class=SDescription></td></tr><tr class="SProperty SIndent2"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.fontStretch" id=link8 onMouseOver="ShowTip(event, 'tt8', 'link8')" onMouseOut="HideTip('tt8')">fontStretch</a></td><td class=SDescription>Multiplier to condense or expand font width. </td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.textColor" id=link9 onMouseOver="ShowTip(event, 'tt9', 'link9')" onMouseOut="HideTip('tt9')">textColor</a></td><td class=SDescription>css spec for the color attribute.</td></tr><tr class="SProperty SIndent2"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.enableFontSupport" id=link10 onMouseOver="ShowTip(event, 'tt10', 'link10')" onMouseOut="HideTip('tt10')">enableFontSupport</a></td><td class=SDescription>true to turn on native canvas font support in Mozilla 3.5+ and Safari 4+. </td></tr><tr class="SProperty SIndent2 SMarked"><td class=SEntry><a href="#$.jqplot.CanvasAxisLabelRenderer.pt2px" id=link11 onMouseOver="ShowTip(event, 'tt11', 'link11')" onMouseOut="HideTip('tt11')">pt2px</a></td><td class=SDescription>Point to pixel scaling factor, used for computing height of bounding box around a label. </td></tr></table></div></div><!--END_ND_SUMMARY--></div></div></div>
