Chart values in legend or on the chart, and tooltip issues

[rdelaplante]

Hi,

Before a create a ticket for this feature request I would like to discuss it here first. I'm using bar charts and pie charts. Users have to hover over each bar or pie slice to get numbers. When I look at reports in other applications they display the values in the legend, and/or beside the bar or pie slice.

I also noticed when hovering over the bars/slices in Firefox (I'm on the latest Firefox and flash), the tooltip containing the number flickers and goes away before you can read it. When I do this in Chrome or IE the tooltip usually stays put so I can read it although I sometimes have to move the mouse a bunch of times to make it re-display then stay put. So I don't think this is a Firefox issue.

I also noticed the tooltip on the bar chart with series gives a bit too much info: Series Name : Bar name : bar index within series : bar value. The bar index within series shouldn't be there? It just confuses users since it is a number just like the bar value.

I'm using PrimeFaces 3.0.M3 on GlassFish 3.1.1.

Thanks,
Ryan

Hi Ryan
About the the tooltip flickering, it was an issue in 3.0M4 for charts without a Title. For 3.0RC1, it looks like the issue was solved for Pie Charts, but not for Bar Charts. Could you confirm your charts do not include a title?

About the Bar Chart Series tooltip giving too much info, I completly agree with you. I think the X-Series name and the bar index are redundant. Why can't we just hide the index from the tooltip?

Hello, I'm using primefaces 3.0 final and the tooltip of the PieChart still flickers if there's no title. I also agree about the index in the tooltip.. I think that's useless information.

I can confirm the bug with the barchart. As a workaround, add an empty title if you like:

Code: Select all

<p:barChart title="&#160;"

Empty string

Code: Select all

title=" " 

doesn't work.
