anitha Posted October 14, 2009 Report Share Posted October 14, 2009 Hi, I wrote the following java code for generating the flash chart: ChartServer ch = new ChartServer(); ch.setChart3D(false); ch.openData(COD.VALUES, 1, 100); for (int i=0;i<99;i++) { ch.setValue(0, i, java.lang.Math.random()* 80); } ch.closeData(COD.VALUES); FlashWriter w = new FlashWriter(); Axis axis = ch.getAxisY(); axis.setMinorStep((short) 5); axis.setMinorTickMark(TickMark.INSIDE); axis.setMinorGridlines(true); axis.getMinorGrid().setColor(new java.awt.Color(255, 0, 0)); ch.setInsideColor(new java.awt.Color(192, 192, 192)); axis.getGrid().setColor(new java.awt.Color(0, 0, 0)); axis.setAlternateColor(new java.awt.Color(255, 255, 255)); axis.setInterlaced(true); ch.setOutputWriter(w); ch.getHtmlTag("400","400","Flash");I am getting an exception while generating Flash Chart using ChartFx6.5 for java, 17:52:40,956 ERROR [[knchart]] Servlet.service() for servlet knchart threw exceptionjava.lang.NullPointerException at SoftwareFX.internal.ChartFX.Internet.Server.Chart.yZYw(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.WZYw(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.zZYw(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.V$ww(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.wZYw(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.Vxww(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.Chart.yxww(Unknown Source) at SoftwareFX.ChartFX.Chart.getHtmlTag(Unknown Source) at SoftwareFX.ChartFX.ChartServer.getHtmlTag(Unknown Source) I wrote the above java code by looking into the flash.jsp example given in Chartfx samples folder.But while using that in Java code i am getting this exception.Could you please explain me the behavior of getHtmlTag function.Can we use getHtmlDataEx function for generating the Flash Chart?Thanks,Anitha Quote Link to comment Share on other sites More sharing options...
