fusioncharts仪表盘定义一个title或称caption

即在xml中定义annotations，申明text来输出一个标题：

<chart manageResize="1" origW="350" origH="200"  palette="2" bgAlpha="0" bgColor="FFFFFF" lowerLimit="0" upperLimit="100" numberSuffix="%" showBorder="0" basefontColor="000000" chartTopMargin="5" chartBottomMargin="5"  caption="设备运行状态实时监控" subCaption="xxxxd" toolTipBgColor="009999" gaugeFillMix="{dark-10},{light-70},{dark-10}" gaugeFillRatio="3" pivotRadius="8" gaugeOuterRadius="120" gaugeInnerRadius="70%"  gaugeOriginX="175" gaugeOriginY="170" trendValueDistance="5" tickValueDistance="3" manageValueOverlapping="1" autoAlignTickValues="1"><#rt>
