Cewolf help in tooltips

[Phillip Sulvan]

Hi..
i am new at cewolf.. but checking the examples and the war, i was able to make a timeseries chart. it is working excepts for the tooltipgenerator... i tryed tons of stuff and didnt get it working for a timeseries one...
i checked the tutorial one, and it works. and my timeseries cant generate...

i even put

public String generateToolTip(CategoryDataset arg0, int series, int arg2)
{
System.out.println("arg0: "+arg0.toString()+ "series "+series+" arg2"+arg2);
return seriesNames[series];
}

to check how it was generating the tooltip. but couldnt make equal in the timeseries... seems it dont execute this method...

please help

How are you specifying the tooltip generator in the JSP?

here is my chart

<jsp:useBean id="lineRenderer" class="de.laures.cewolf.cpp.LineRendererProcessor" />
<jsp:useBean id="pageViews" class="de.laures.cewolf.example.PageViewCount"/>
<cewolf:chart id="line" title="Umidade" type="timeseries" xaxislabel="Tempo" yaxislabel="Umidade">
<cewolf:data>
<cewolf:producer id="pageViews"/>
</cewolf:data>
<cewolf:chartpostprocessor id="lineRenderer">
<cewolf:param name="shapes" value="false" />
<cewolf:param name="outline" value="true" />
<cewolf:param name="useFillPaint" value="true" />
<cewolf:param name="fillPaint" value="#FFFFFF" />
<cewolf:param name="useOutlinePaint" value="true" />
<cewolf:param name="outlinePaint" value="#000000" />
</cewolf:chartpostprocessor>
</cewolf:chart>
<p>
<cewolf:img chartid="line" renderer="/cewolf" width="800" height="600">
<cewolf:map linkgeneratorid="pageViews" tooltipgeneratorid="pageViews"/>
</cewolf:img>

the chart is working, only the tooltip that isnt... seems it isnt being called.. but i cant find in the examples where "to call" it.

ps: the method productdataset is returning a TimeSeriesCollection... ( that is the only difference from the example tutorial.jsp that return a DefaultCategoryDataset) and i cant figure why the generateToolTip isnt being called

You can check out the HTML that gets generated. It should have a <map> tag with onmouseover and onmouseout event handlers.

Also please check your private messages and act accordingly.

I have this as html generated.

dunno what is wrong on my bean...

i have the following structure there..

public class PageViewCount implements DatasetProducer,
CategoryToolTipGenerator, CategoryItemLinkGenerator, Serializable {
public Object produceDataset(Map params) throws DatasetProduceException {
TimeSeriesCollection ts = new TimeSeriesCollection();
//alot of code
TimeSeries[] testts;
//a for to run resultset and create timeseriesdataitem and adding to the
//TimeSeries array using a method to locate which series it is then
ts.addSeries(testts[x]);
return ts;
}
public boolean hasExpired (Map params, Date since)
{
return System.currentTimeMillis() - since.getTime() > 5000;
}
public String getProducerId()
{
return "PageViewCount DatasetProducer";
}
//yes.. those 2 methods i know is Wrong.. but seems they arent getting executed
//.. so... dunno what i am missing...
public String generateLink (Object data, int series, Object category)
{
System.out.println("LINK: "+seriesNames[series]);
return seriesNames[series];
}
public String generateToolTip(CategoryDataset arg0, int series, int arg2)
{
System.out.println("arg0: "+arg0.toString()+ "series "+series+" arg2"+arg2);
return seriesNames[series];
}
}

if possible, has any example of this method generateToolTip working on a timeseries?


ps: how do i assure that the method generateToolTip is being executed?

Thanks in advance.

hi.. hello again

i managed to "generate tooltips" by adding the following code to my jsp...but, i really dunno why the method (generatetooltip) is being called on the java...
here is the code

<%
// create example link generator for the overlaid chart
final SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
XYToolTipGenerator tooltipGenerator = new XYToolTipGenerator() {
public String generateToolTip(XYDataset data, int series, int item) {
Date d = new Date(((Long)data.getX(series,item)).longValue());
return "Time=" + dateformat.format(d) + ", Y="+ data.getY(series,item);
}
};
pageContext.setAttribute("tooltipGenerator", tooltipGenerator);
%>

now the problem is :
- the tooltip being generated is "a time + the y value of the chart".. i dont want to get y value.. maybe i want.. dunno yet.. but seriusly i want is the "Name of the Serie". ( dunno how to get this... for this timeseries chart )
- Figure out why it didnt executed the method from the .java

any help/idea?

The tooltip is returned by the generateToolTip method - you're free to make it do anything you want. It's one of the advantages of implementing the DataSet, the ItemLinkGenerator and the ToolTipGenerator in the same class that usually all required data (like the series names) is available there.

- Figure out why it didnt executed the method from the .java

Could have something to do with the fact that the first code implements CategoryToolTipGenerator, while the second code implements XYToolTipGenerator.

ok.. solved one problem, the "name" of the series on the tooltip

return "Time=" + dateformat.format(d) + ", Series="+ data.getSeriesKey(series).toString();

now, kinda done but appreciate any help in that other problem.. how to execute the generatetooltip in the java, so i can take out that method from my jsp

thanks in advance...

i have a "timeline series chart" from a timeseries collection... when i executed the second code (in the jsp) it worked somehow.. then i tryed to reproduce it on the java as a tooltipgenerator using a xydataset. it compiled without problems, but didnt get executed. dunno what i am missing here.

[Phillip Sulvan]

kinda solved..
just recreated the producedataset method again.. now working.. dunno what was happening..maybe i miss something.. anyway.. thanks
