When I use the mouse point to the bar, it shows USD/GBP: X=1

[Carrie]

I have used BasicTimeSeries to create dataset and modify the createUSDTimeSeries to creatMyTimeSeries and then use createVerticalXYBarChart to create the chart

When I use the mouse point the bar, it shows
USD/GBP: X=1,036,080,000,000, y=9

What is the value of x mean?
Is the the day time??
If yes, how can I convert it back to date (and where to do it)

If Not, can I disable the message (and how to do it)??

Anyone can help? It's urgent. Many Thanks

Hello,

What You see when "When You use the mouse point the bar" is the Tooltip. It is extra information about the datapoint where Your mouse is located.

You can set the tooltip off, or customize it with special formatter, or even write You owns TooltipsGenerator classes.

By default, the createVerticalXYBarChart() method in the ChartFactory uses a StandardXYToolTipGenerator()...

I'm not very familiar yet with the all API, but You could perhaps set the toolTipsGenerator of Your renderer (method setToolTipGenerator in XYItemRenderer) to a TimeSeriesToolTipGenerator providing the dateFormat You wish.

thx, but do you know how to disable tooltip which show while the mosue point to the bar?

Hello,

Use the setToolTipGenerator method passing a null argument.

Hello,

Some code example :
1) using the constructor of createVerticalXYBarChart(String title,
String xAxisLabel,
String yAxisLabel,
IntervalXYDataset data,
boolean legend,
boolean tooltips,
boolean urls)
--> simply set tooltips value to false

2) if You already have a JFreeChart instance, let's say chart, You can write :
((XYPlot) chart.getPlot()).getRenderer().setToolTipGenerator(null);

In my case I have the tooltips set to true, but nothing shows up. Do I have to write any code for the tooltip to show ?

Thanks

If you use the ChartFactory class to create your chart, and set the tooltips parameter to true, and display your chart in a ChartPanel, then the tooltips should appear. If that doesn't happen, there is a bug somewhere.

Found my mistake !!
I was trying to look for a tooltip in an image file !!
What is the easiest way of seeing a tooltip in a jsp ? I dont like to put too much code in JSPs

Thanks
