ChartFactory.createStackedAreaChart() with CategoryDataset ?

[deepika]

Hi Everyone,

Here is something very simple, I am trying to do. I am trying to create a stacked area chart using ChartFactory.createStackedAreaChart() with CategoryDataset. But to my surprise, tooltip behaves very different compared to using ChartFactory.createAreaChart() with CategoryDataset. When I say it behaves different, I mean that for formar case, I have to move the mouse to the (X,Y) intersection to display the tooltip while later displays the tooltip no matter where the mouse is on the chart.

I am using Jfreechart version 1.0.3. I am also attaching the sample example I am working with.

Can anyone please help me here. This is really urgent. I have also bought JFreechart developer guide so any reference to that can also be helpful.

Thanks,
Deepika

You should use another subject for this thread - like "Tooltip" behaviour in StackAreaChart"...

[deepika]

Hi Everyone,

I am trying to create a stacked area chart using ChartFactory.createStackedAreaChart() with CategoryDataset. But to my surprise, tooltip behaves very different compared to using ChartFactory.createAreaChart() with CategoryDataset. When I say it behaves different, I mean that for formar case, I have to move the mouse to the (X,Y) intersection to display the tooltip while later displays the tooltip no matter where the mouse is on the chart. Is it possible that there is some kind of bug in ChartFactory.createAreaChart()?

I am using Jfreechart version 1.0.3. I am also attaching the sample example I am working with.

Can anyone please help me here. This is really urgent. I have to use CategoryDataset because the values on the X-axis are strings( NOT numbers). Any suggestion on as to how could I get tooltips working in the same way as it does for ChartFactory.createAreaChart().

Thanks,
Deepika
