How to add tooltip to images?

How to add tooltips to images?

OK, here is a more robust, more generic (any node) implementation.
It would be nice if I could find a way to automatically insert the tooltips in the scene, but at time of node with tooltip creation, scene doesn't exist yet... Should have a post-layout event, perhaps. Or I can do that once on the onMouseEntered event, but then I have to find a way to get the scene holding a given node. Tried to iterate on Parents, but I can't cast a Parent to a Scene?
Anyway, here is the new code:
Tooltip.fx
public class Tooltip extends CustomNode
public var text: String;
public var fill: Paint = Color.web('#EEFF00');
public var stroke: Paint = Color.GREEN;
var label: Label; // Make public to access textOverrun, textWrap, etc.?
var back: Rectangle;
override function create(): Node
    label = Label
      text: text
    back = Rectangle
      x: -2, y: -1
      width: label.width + 4
      height: label.height + 2
      fill:   fill
      stroke: stroke
    Group
      content: [ back, label ]
init
    visible = false;
    layoutInfo.managed = false;
WithTooltip.fx
public mixin class WithTooltip
/** The tooltip to display. */
public var tooltip: Tooltip;
// We display the tooltip after a while being over the node
var tooltipTL = Timeline
    keyFrames: KeyFrame
      time: 750ms
      action: function ()
//~         println("visible {%.0f tooltip.boundsInParent.minX} {%.0f tooltip.boundsInParent.minY}");
        tooltip.visible = true;
var baseMouseMoved;
var baseMouseEntered;
var baseMouseExited;
postinit
    var tooltipNode = this as Node;
    baseMouseMoved = tooltipNode.onMouseMoved;
    tooltipNode.onMouseMoved = function (evt: MouseEvent): Void
      if (not tooltip.visible)
        tooltip.translateX = evt.sceneX;
        tooltip.translateY = evt.sceneY - 20;
      baseMouseMoved(evt);
    baseMouseEntered = tooltipNode.onMouseEntered;
    tooltipNode.onMouseEntered = function (evt: MouseEvent): Void
//~       println("onMouseEntered: {%.0f evt.sceneX} {%.0f evt.sceneY}");
      tooltipTL.playFromStart();
      baseMouseEntered(evt);
    baseMouseExited = tooltipNode.onMouseExited;
    tooltipNode.onMouseExited = function (evt: MouseEvent): Void
//~       println("onMouseExited");
      tooltipTL.stop();

I have no idea how to set up a pie chart for tracking spending with categories

This is what I want to do to help me track my credit card spending.
I want to make a Numbers sheet where i can jot down how much money i spent on a item, and what category that item would go with (example, food, electronics, gas, so on).
and then i want to have a pie chart that will show much how much money i'm spending in each category and how much of a percentage of the total each category takes up of the whole.
I have no idea how to set this up in a sheet. I tried typing it in a few times and every time i go to make a pie chart, it never shows me any of the results i want to see.
can someone please help me set up a sheet to be able to get this information to display correctly in a pie chart?

Brad,
Create a table with the categories and the data (for now you can make up the data):
Now add a chart from the Charts menu in the toolbar:
Now click the "Add Chart Data" button just below the chart.
Now select data (from column B) in the table. Last trick is to click the menu at the bottom-left corner of the window and change the selection to "Plot rows as series" :
Now add formulas to the table to properly summarize the data from your data entry table using the sumif() function.

How to Get Lines in Pie Charts

Using CF7 and WebCharts3D, and got my pie chart working. Only
problem, I can't figure out how to get it to show LINES from the
label of each pie slice, to the label's corresponding slice. The
pie slice labels (descriptions) appear outside the pie chart, which
is where I need them. But when you get a pie chart with a lot of
slices (say 8 or more) and a lot of smaller slices close together,
it's hard to tell which label applies to which slice. Hope this
makes sense.
All I need is to ADD A SMALL LINE from each label to it's
corresponding pie slice. I've looked for options in WebCharts3D to
do this, but can't seem to find anything (in the Decorations,
Series, etc., sections).
If this is possible (getting these lines to appear) could
someone please advise how to do this? Greatly appreciate any
help/advice. (It's probably something very easy, and I just missed
it).
Gary

I was afraid of that. Just wanted to make sure I wasn't
missing something. Thanks for the note and for confirming. Much
appreciated.

How can I create a Pie charts ?

HI all,
I'm a beginner in java and i'm investigate in a web project (website) which should display statistical charts. I did a beans to generate basic bar charts, but it is most difficult to build a Pie chart. That's why i need help to put me on the rigth way to build Pie Charts beans (this pie charts should be filled up with db query).
Every kind of help will be appreciated.
Thanks in advance
Hope someone can help me.

I take it you constructed the bar graphs using html and images together?
Obviously it's a little more difficult to make a pie chart with html. Chances are that it will have to be an image rendered by a Servlet or JSP. I suggest looking at how to create images using AWT or swing. This will allow you to create a circle with different color slices and what not. Then you need a Servlet or JSP that will send the image out the output stream. You can then place an image tag in your html page like this <img src="http://myserver.com/PieChartServlet>
I'm actually working on an API myself that will render pretty histograms (line graphs), and hopefully pie charts down the road. It's going to be an open source project. I decided to make my own API when I looked at some others out there who were charging an arm and a leg for theirs. Chart Builder for example, it's like $6K for their java based API <choke>.
So if you're interested, or anyone else is, shoot me an email and I'll let you know when the beta is ready. [email protected]

Thanks a lot for your reply.
But it shall works in a beans and this was set up only for applications or applet. Besides it seems (i'm really not sure but i have found lot of thread)that an applet can't be run into a jsp page that is searching data into db (thanks to sql query)
: there is a problem of buffer (tomcat can't generate the jsp page in the same time as it execute the applet).
Let me know if i'm wrong or not please ?

I am wanting to add an interactive pie chart to a custom form

The pie chart or "wheel" is a visual for my project status form I want to share with clients. Can this be done? I only see an option to insert an image.
thanks

Currently we only support one field/item on a line. We are working on adding a feature that allows you to put multiple fields/items on a single line. We hope to have that out in a few months.

How to add Oracle Graphics 6i charts (OGD) to my Oracle Reports 10g

Hi,
Is there any possibility to add Oracle Graphics 6i Charts (.OGD) to Oracle Reports 10g
(OR)
If not possible, Can you please provide steps to migrate OGD to any format that is supported in Oracle Reports 10g.
Regards,
Swethan

Oracle Graphics and its OGD image format are no longer supported. Reports built with previous versions of Oracle Reports containing Oracle Graphics charts will continue to run in Oracle Reports 10g Release 2 (10.1.2) if the Oracle Graphics 6i runtime is installed on the same machine in a separate ORACLE_HOME. However, this is not a supported configuration, and Oracle will not fix bugs that result from this configuration.
Re-create all Oracle Graphics 6i objects using the Graph Wizard
