Xml :: Flex - Retrieving Sub-XML Elements To Display A Pie Chart?
Feb 9, 2011I have designed an application that will load the information from an XML File to a Pie Chart.

Flex :: Prevent A Default Chart Item Roll Over Highlight In A Spark Column Chart?
Mar 3, 2011I'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.

Aug 26, 2011I am trying to programmatically skin a PopUpButton control in Flex Builder, but having no luck. As far as I know this requires writing a custom skin class or creating a modified version the control class itself (since the control is MX and not Spark). Again, just to clarify, I want to programmatically modify the appearance not simply set styling properties or display an image. I've been able to do this programmatically with other MX controls (e.g. tabs in a tab navigator), but not with the PopUpButton.I think part of the problem may be that the control is actually composed of two separate buttons, so you cannot draw just one rectangular area over the whole control.
View 1 RepliesFlex :: Creating Programmatic Skins For Canvas
Mar 24, 2010I am having 2 problems creating programmatic skin for Canvas.
First problem: I would like to have background with rounded corners and I am using GraphicsUtil.drawRoundRectComplex in order to have round corners for only the upper two corners. The problem is that drawRoundRectComplex takes for each corner one single parameter - the corner radius. However my scaleX and scaleY factors are different and in fact the corners are not properly rounded because I either can set the radius using scaleX or scaleY. Graphics.drawRoundRect is better because it takes two parameters for the corners - elipse width and height and then you could apply both scale factors but it doesn't allow me to specify different radius for different corners. How to use GraphicsUtil.drawRoundRectComplex when scaleX and scaleY are different.
Second problem: Even though I set my programmatic skin through style - <> the skin's updateDisplayList gets executed only once and after that somehow "backgroundImage" style gets "undefined" and my programmatic skin is not associated anymore to the Canvas instance. As a workaround I am setting on each resize event "backgroundImage" style again but this is ugly. What could cause such "silent" resetting of the "backgroundImage" style to undefined?
Flex :: Animate Between States In A Programmatic Skin?
May 12, 2010I have a button with the various states (up/over/down etc) that uses a skin file to render the display. I want to achieve animation between the states. For instance, between the change from 'up' to 'over' I want to fade in a color and a border.
The way I am doing this at the moment is to use viewstates and animate between them using transitions and the mx:AnimateProperty. However, using this method I can only animate one property per viewstate. So only the border, or the color can be animated.
Does anyone know how I can achieve multiple animations on multiple properties of a programmatic button skin?

So, if I sort the data,only the perticular page is being sorted. So,I need to sort the entire list by the column criteria.I tried HeaderRelease event,but I guess it is of no use as I need to make a round trip call to the server to get the sorted data.Is there any way I can implement that.I also need to show the sort markers in the Column headers' right position, indicating the sort numbers and direction.

Feb 10, 2011When I create something like the following:

View 1 RepliesFlex - Options To Create Line Chart In Flex For Data-intensive Web App?
Jan 13, 2012My group is working on a Flex/AS3 scientific web application that is data intensive. Luckily the only plots involved are line charts. However, each line chart may have multiple traces (up to 24), and each trace may contain up to 2000 points. The user will need to zoom in and out and interact with the data (e.g. data tips, etc.).
The response I'm getting from developers is that's a lot of data to render in a plot in Flash. For reasons beyond the scope of this post, we can't sample the data to reduce the size (this has already been done and nature of the data prevents further sampling).
Rendering speed is critical for this app. What kind of rendering speed should I expect the Flex 4 line chart component to provide for a given number of points (e.g. 1 second to render 1000 points?)
Are there products available that handle plotting large data sets better, which can be incorporated in Flex (I've seen FusionCharts and ZingCharts online but have no idea how they compare with Flex's components)? Of those, which are easy to develop with while still providing a lot of flexibility in look and feel?
Actionscript 3 :: Flex - Possible To Have Flex DataTips On Canvas Rather Than Chart Objects
Jan 17, 2010Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.
I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,

Flex :: Adobe Flex - Doing Group By At Client End (DataGrid To Pie Chart)?
Dec 23, 2010I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)
Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12
and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?
Get Fine Grained Programmatic Control?

I know this is possible by using LegendMouseEvents, as the events give access to the LegendItem that has been clicked/rolled over ect. However, I cannot rely on an event in this case.

1 Dimensional Chart In Flex?
Apr 15, 2011I want a bubble chart that just shows items along a straight line. So I'd like the horizontal axis to essentially not exist. I have it working right now with the yField assigned to a field that happens to always be '1' on my test dataset.. but this is not going to be the case in general, so I need some way to restrict the y-axis... preferably without needing to go back to my model and parse through all my data to add a dummy value '1' on each entry.
Unfortunately setting min/max values just cuts off anything above or below rather than restricting entries.
I set computedMin and Maximum (no idea what they are and the docs don't really explain) but it didn't seem to restrict the data in any way.

ActionScript 2.0 :: Connecting Looped Programmatic Tweens To Their OnMotionFinished Events?
Mar 6, 2007I'm working with the Tween object: I'm building a game where mc's need to drop periodically from the sky, and then when they reach the bottom of the screen, they need to be unloaded. The problem I'm having is firing "onMotionFinished" events for these dynamically, "loop-generated" mc's. I think I need to be able to send parameters to an onMotionFinished function, but I can't figure out how. I made a stripped-down version of what I'm doing, here's the code:
Code:
import mx.transitions.Tween;
import mx.transitions.easing.*;
//this keeps track of which bomb we're on
bomb_count = 0;
[code]....
Basically I just want to have more control over the programmatic tween and its associated events. Everything is there, it's just that the onMotionFinished event isn't attached to the tween I want it to be attached to, it's attached to the most recent tween that occured, or something. I suspect it has something to do with the fact that all my tweens have the same name, but I don't know how to name them differently in the loop.
I read some stuff about "delegates" and "superclasses" and other dizzying objecty things that seemed relevant but like I said, since I'm not oop fluent, I get pretty lost pretty quick, esp.
Flex :: Placement Of Legend For A Chart?
Jun 22, 2009I would like to be able to specify the placement of a legend for a linechart. Currently, it continues to appear to the right of the chart. I have tried playing with the width/height of the chart to no avail... Putting the legend before the linechart in the mxml causes it to appear to the left. I can't seem to get it appear at the bottom though. I can't seem to find any good examples for this. They don't seem to specify anything but the legend usually shows up below the chart, I can't seem to do it.
View 1 RepliesFlex :: Speed Up Chart Rendering?
Jul 10, 2009I'm using a lineseries chart, but it gets fairly slow to re-render when I add a new point when the total # of points is ~1200 points. Granted, this is running on a fairly slow PC (~600 MHz). Reading the Flex documentation on how to speed up rendering (turning off dropshadows, turning off filterData, etc...) doesnt seem to help. I bound my chart to an ArrayCollection (rather than the array I used before which I manually updated) and it doesnt seem to be any faster. Adobe's documentation seems to have me believe that the Chart looks only at what changed since the last time it was updated, but i'm only adding one point!
If their info is correct, why does it take significantly longer (5 seconds) to update one point when I have ~1200 points then when I only have 2 points (instantaneous)? FYI - When I add a new point to my ArrayCollection, I have to do a "AC.refresh()" to get the DataBinding to pick up the new data.
