Flex :: Change Starting And Ending The LineChart Of JSON Data With Slider?
Feb 28, 2011
My JSON Data file ise data.txt
[
{
"sayim":"1",
"x":"400",
[code]...
and my aim ise to create a Slider which can change starting and ending of the graphic, it is like what is showing in figure 6 in this website and here the MXML codes;
Adobe Flash Builder: How to make a function to play video starting from one second and ending in another? So I havein MXML simple video player tag. I need some function to play that video from second X to second Y and pause it. How to do such thing?BTW: we asume file is embeded into SWF.
Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData); public function getGridData():String {[code].....
However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
I've compiled an MTS video into MP4 format using FFMPEG. The video is 2 minutes long.
I want to be able to play the video back but start at 0:15 seconds and end at 0:45 seconds. Effectively I want the playback software to only show 30 seconds of playback available. The software must be a Flash-based application for integration into HTML.
i am working on a line chart on flex which enable me to view the progress of data according to the year. I have tried using a slider to filter but it doesn't seemed to work.
How do you display data on a LineChart that cuts off where there is no more data? For example, if I am showing a chart of company revenue for 2010, the chart should only show up to July now (with August and forward on showing no data). This would make the line in the line chart break and dissappear off at about midway through the year.
why the data points on the LineChart don't line up with the corresponding tick mark / horizontal axis label? See adobe's example (at the bottom of the page):[URL]See how the data for 7/28/05 is to the right of the 7/28/05 tick mark / label?
I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:
var send_lv:LoadVars = new LoadVars(); send_lv.data = JSON.stringify({some json object}); var response_lv:LoadVars = new LoadVars(); response_lv.onData = function(rawdata) {
[code]....
In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?
I have to work with webservices in Actionscript. I found the following code that allows me to use JSON URLs that implement only the GET method. However, it doesn't work for POST methods (doesn't even enter the "onComplete" method). How can i "POST" JSON data using Actionscript 3.0?
Is it possible to change the starting value on an axis for a chart in Flex 3.4? For example, rather than the y axis starting at 0, have it start at 50.
I am using JSON to parse HTML data with customized html tags in Flex. Flex's support for HTML is pretty minimal, so I am wondering if it's possible to do a simple font color change rollover effect on these links. Currently I have found that Flex only supports a few HTML tags, but also supports CSS through Flex's whack CSS methods. Can I manipulate HTML that is written in my JSON files through an external CSS file? Or better still using a simple tag with the JSON file?
The JAX-RS service receives the request and respond successfully with some dummy response, but I have no access to the request.data field.
How do I access the data of the request message (which is {"type":"get_configuration","data":"some data"} in this particular example)? I think that I'm supposed to add some parameters to the handleMessage method like
public SomeResponse handleMessage(Object message) {...
but this does not work at all. The request got 415 response.
I have a nested MC that functions as a continuous slider; when you mouse right of center it slides one way and when you mouse left of center it slides the opposite direction. Right at center it stops. The problem I have is that I'm using this as a menu at the bottom of a .swf and there are other places to mouse on the page, which means that this menu is constantly in motion even when it's not being used. I want it to stop when it isn't being used, only because it's an MC I can't use the onMouseOut command to stop the clip. I tried making a button that targets the clip and stops it when you roll over the button but it doesn't work.
Here's the script I'm currently using: onClipEvent (mouseMove) { xcenter = 467.5; speed = 1/25; } onClipEvent (enterFrame) { var distance = _root._xmouse-xcenter; [Code] .....
I am having a set of slider for each bar in the graph. I have bindded all the sliders with their corresponding bars. When i change the value of slider the value in the ArrayCollection changes and i have also used
I have a line series in a linechart and a slider that goes from 0 to 200. When I now move the slider, I want to have a dot appearing at the chart so when I move the slider to 150, there should be a dot where the x-coordinate of the chart is 150.
I have a LineChart with a DateTimeAxis as horizontalAxis and a maximum set. If a point is beyond the maximum date, the whole segment will not appear. Yet, is there a way to make it appear until it reachs the border of the chart?The code here :
<?xml version="1.0"?> <!-- Simple example to demonstrate the DateTimeAxis class. --> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
how can i create mx:LineSeries dynamically depending upon array collection values. Now only 4 line series is there but some times i have to show more as per the array collection values change ex: if one more status HoldProject added to array collection?
Is there a way to break the line in a line-chart, if the gap between 2 values on the x axis is bigger then a given value? For example there are 20 values but the first 13 are close to each other on the x axis and should be connected with a line, but the other 7 are a bit far from these and should be connected with another line. The type of values are the same.
I have a line chart with 4 line series with diamond, circle, box and triangle as item renderer for the plots for these 4 line series.Now my requirement is I want to show labels for the plots in the chart. It should be like this : I tried with some item renderes but not getting it correctly since I want to use the circles and triangles to render the plots.
I have a radio button group within a data grid, whenever I attempt to change the selected radio button the web page crashes. Below is how I put together the radio button in the data grid.
If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.
I have a Flex3 LineChart component using an CircleItemRenderer and the datapoints are being cut off because they are too close to the edge. Here's what it looks like: [URL] As you can see, the circles on the left and right sides are being cut off. How can I make the LineSeries area, plus the horizontal labels, narrower so it fits in the chart area?
I'm doing some line charts in my Flex application, and I need to draw segments of those line chart in different color. Does anyone have an idea how this could be achieved? For instance, if I have a code like this (actually, I have given this trivial example for simplicity (the problem is the same)):
I'd like to put a label to each LineSeries on my Flex LineChart so it will be shown next to the line (along it). Any relatively easy way to archieve that?
I have a line chart in flex with a dateTime axis. I am setting the dataprovider to that linechart via actionscript. The graph gets drawn. The problem occurs when i assign a null to the dataprovider so that the graph becomes empty.
Actual code looks similar to the code below :
var actualValues:XMLList=flowChartDP.upFlows; var localSeries1:LineSeries = new LineSeries(); localSeries1.dataProvider = actualValues;
I need to create LineChart that display datetime points, for example:
public var stockDataAC:ArrayCollection = new ArrayCollection( [ {date: "2005,7,27,22,15,30", close: 41.71}, {date: "2005,7,27,22,16,30", close: 42.21},
