Flex :: Programmatically Display A DataTip In Chart (without Hovering With The Mouse)?
Jun 15, 2010
I would like to show a dataTip on a flex chart by setting the selectedIndex property of the AreaSeries. For instance, if selectedIndex = 2, then a dataTip appears over the third item in the series. Is this possible in Flex 3.5? .

I have a following issue:My task is to style a datatip for two charts in Flex 4.5.Both charts reside in two different <Group> based components which are added to the <Application>
So after a thorough research here is what I tried to do.First applying a css descending selectors:
#container#chart1 chartClasses|DataTip{
backgroundColor:white;
backgroundAlpha:0.01;
[Code]....
Then I would like to be able to get access to the instance of the CustomDataTip class.But I can't .So currently the only thing I can do is to create a distinct custom datatip renderer class for each chart.That could be fine if you have only a couple of charts you want to style but what can we do if we have many of them?

I have a LineChart that contains multiple series, both LineSeries and PlotSeries, and I have a custom dataTipFunction set for the chart. However, I only want data tips displayed for line series, not the plot series. I have tried returning null from my format function, but that just displays an empty box. I have also tried disable mouse events on the plot series (by setting both mouseEnabled and mouseFocusEnabled to false), to no avail. Is this even possible?

I need to display price of item for every date in the month. The chart can be Bar chart or plot chart.
Question: Suppose there is no data available for 01/15/2010 then, Is there a way to display (01/15/2010) on x axis but no (bar or plot point) corresponding y axis point ?
i.e. there will be a empty space between 2 bars or plot points.
Currently i am using 0 , But 0 is a valid value.
Let me know if such a display is possible.

I have designed an application that will load the information from an XML File to a Pie Chart.
First my XML looked like this
[Code]...
Now this works perfectly and I can see the generated Pie Chart.But now let's say that I changed the XML in the following manner.
[Code]...
in the results event how do I access it? bookStock = evt.result.books.stock.bookinfo; doesn't work. I get a "Error: Unknown Property: 'bookinfo'." When I analysed the bookStock object I get this. How do I access the XML element now? Does anything needs to be changed here?

I'm trying to prevent a default chart item roll over highlight in a Spark column chart.If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent.
So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either.

I'm using a Flex ColumnChart with a custom dataTipRenderer. I'm able to apply a nice skin with the dataTipRenderer, but am not sure how to move the datatip to be centered. Is there a way to have the chart center the data tips over the column instead of the normal top-right alignment the chart does?
Instead of:
|tip text|

I have a datagrid with one datagridcolumn in it. Without a custom itemrenderer I can use a datatipfunction for showing a custom datatip but now I want to have a custom item render for colouring the rows differently.Therefore I extended a label and changed the data method but now my datatipfunction does not work anymore.

So I had an interesting request from a client the other day. Basically, he wanted the button (which looks like a sticker) to peel off as the mouse approaches the button. So from the outside of the hover point, it would peel a little. As the mouse gets closer, the peel animation would peel more (or less, depending on the mouse position) until it is 'peeld' off the page and sort of hovering above the background when the mouse is finally over the button.
Does anyone know of some custom classes that might achieve this? It seems like it would be making use of the new 3D in flash10, but I haven't had much time to experiment with 3D in flash.

I am basically trying to create a display object transformation manager which will allow me to scale/rotate objects. I am currently trying to figure out how to rotate an object so its corner follows the current x and y of the mouse. I always get confused on the math of things like this. I know how to listen for the events and everything, I just am unsure of how to calculate the amount of rotation to apply. I will probably be rotating via a Matrix so I can rotate the object around its center, rather than the upper-left corner of it. My question here is: how do I get values when I don't want them constrained, like scaleX and scaleY?

Within my component, I'm drawing some rectangles as below:
[Code]...
I need to display a custom tooltip for each rectange when the mouse cursor is hovering over it.
How can I do this? I'm using the MouseMove event to track when the cursor moves over these coordinates (that part is working), but when I change the tooltip text it's not refreshing
private function this_MOUSE_MOVE(event:MouseEvent):void
[code]...
EDIT: The problem seems to be with the following line:
ToolTipManager.destroyToolTip(_myToolTip);
If I comment out the preceding line, it will display the new tooltip, but it will keep creating new ones and the old ones never get removed. But if I add that line, it doesn't add any tooltips! Is the code not being executed sequentially, i.e., is the code to remove the tooltip somehow getting executed after the code to add the tooltip?

I would like to create a component(extending from spark Panel), which upon a buttonclick should show up next to the button(something like a bubble popping up or like the small box opening up when hovering up on profile links in facebook/twitter). I tried to create a component that implements mx.core.IToolTip and provided the methods required by the interface. And on the toolTipCreate event, set this component as the tooltip.
This works to an extent. When I bring the mouse over the button, the panel appears as the tooltip and goes away when i move the mouse away. What I need is, the panel should appear next to the button when click on it and should go away only when I click outside the panel or click the close button present inside the panel.

I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)
