[Gantt Bar Height]

 I have to set an annotation so that its height is equal to the gantt bar height.

I know it is calculated from the chart height and the no of series.

But I want to know the exact formula so that my annotation height is egual to the gantt bar height.

Note: There is no scrollbar in the graph.

[Onmouseover event not firing while using tooltips]

The onmouseover event got fired and I got the tooltip. Actually the map tag name and the usemap attribute value of the img tag( obtained using the method "renderToStream(OutputStream content, Writer imgMap, Writer htmlTag)" ) were not matching and that was the reason for mouseover event not getting fired.

[Onmouseover event not firing while using tooltips]

I need to get a tooltip over the datapoints of png chart created using Chartfx7.0. I used the following piece of code.

ch.setRenderFormat(imagetype);

ch.setToolTipFormat("?',%S,%N,'" + imageMapName + "','");

ch.getAllSeries().getLink().setReload(false);

ch.getImageSettings().setInteractive(true);

ch.getImageSettings().setToolTips(ImageToolTipStyle.WITH_MOUSE);

ch.getAllSeries().getLink().setUrl(jumpURLBase+jumpURLParameters);

and got the area tag as follows

<area shape="poly" coords="654,16,654,20,680,20,680,16" href="javascript:DoDrillDown(0,22)" onmouseout="popupoff()" onmouseover="popupon('?',0,22,'ImageAvMap','',event)" />

But my onmouseover event is not getting fired when i move the mouse over the datapoints. I have written the popupon and popupoff functions correctly.

[Null Pointer Exception while creating the Flash Chart]

 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 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,

[Problem with Y axis labels while using log scale]

  I am using ChartFX 6.5 for Java.I am not getting the y axis labelproperly when i set yaxis to log scale.I have used the following code.   ch.getAxisY().setLogBase(10);    ch.getAxisY().setStep(10);    ch.getAxisY().setMinorStep(10);   ch.getAxisY().setAutoScale(false);   ch.getAxisY().setMin(yMin);   ch.getAxisY().setMax(yMax);TheyMin is 7.00 and yMax is 10.54.All the data values are in the range8.For this condition I am not seeing any Ylabel on the yaxis. When Ichanged the Ymax value to 100.00 I am getting only one Ylabel value 97.00. Similarly when the Yaxis scale is set to 2.718281828;Ymin=5.00 and Ymax=100.00 I am getting Ylabels as 7.718,22.496,42.582.Couldyou please explain me the behavior how the Yaxis label is set whileusing log scale. Also how can i set the Ylabels in the desired rangelike 8.0,9.0.10.00 while using log scale.
