I need to recalculate the max value of lineChart according to the visible lineseries. In the application I have the ability to make visible or not the lineseries of the graph and if I make not visible the lineseries with the actual top value I want to zoom in and change the top value of the graph.
View 1 RepliesI've created a Flex LineChart that shows high and low tide predictions over time. I'm using the LineSeries with form="curve", which produces a nice sinusoidal wave graph, representing water level over time. The X-axis represents time, and the Y-axis represents water level. The only data points I have to work with are high and low tide values, but I would like to figure out how to determine the y-values of arbitrary x-values along the line.[code]
View 2 RepliesI have a chart in Flex 4 with a LineSeries with a curve form. Is there a way to get a corresponding y value (along the curve) by providing an x value?
View 1 RepliesFinding descendants are easy. But how do you find an ancestor? Consider the attached XML. How would I find the group whose ancestor is subitem(@id=1)? I can get subitem easily, but I don't know how to determine what group it's in.
I would imagine a syntax something like this:
xml.group..(@id==8)
or
var subitem = xml..subitem.(@id==8)[0];
xml.group.(contains(subitem))
But I can't find a way other than to iterate the tree upward from subitem using parent().
I have a number of boxes on screen - each box is a rectangular movieclip, and they fall to the bottom of the screen where they pile up to make a stack of boxes. I'm using box2d for the physics. Oh, and each box may be rotated. I need to find the highest point - ie the smallest y value, of the stack of boxes.
Obviously I can find the position of the highest box's registration point easily (which is the centre of each box) - but that may not be the highest point of the pile of boxes. The highest point may not even be the highest box - it could be a lower box that is rotated on end, for example.
In a LineChart in Flex you can set a LineSeries to interpolateValues="true" what this does is connect missing values so you do not have gaps in your line. But what I would like is for it to insert 0's for the missing fields instead of drawing a direct line to fill the gap.
Is there a way to set it to do that?
the LineSeries is not dynamically added to my CartesianChart...What's wrong in this code:
private function chartComplete():void {
var ls:LineSeries = new LineSeries();
ls.styleName = 'timeline';
[code].....
This is my array collection
[Bindable]private var Projects:ArrayCollection = new ArrayCollection( [
{ Department: "Software", TotalProjects: 73,Completed:30,Inprogress:30,Approved:13},
{ Department: "XML",TotalProjects: 50,Completed:20,Inprogress:20,Approved:10},

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?

You can easily set a stroke on a line series like this:
[Code]...
This will set alpha for the entire stroke to .8 But I want to be able to set a different alpha on the stoke for each plot based on something in the dataProvider. For example the yField in the lineSeries is "Apple" which is how it knows where to plot for the lineSeries. I want to be able to add something like alphaField which tells it what to set the stroke alpha for each plot.

I am plotting an AreaSeries and a LineSeries on a AreaChart using Flex 3 in built chart components. I want to code a custom item renderer for LineSeries to be shown at the intersection points where LineSeries crosses AreaSeries.
View 1 RepliesI am implementing a LineChart in FLEX 4. I have the chart working well except I do not like the default colors and cannot use them, as they do not relate to my data very well. For instance, Orange is not a great default color for my data column "Outdoor temperature". I would rather override it and use a green color if possible.
When I explicitly specify the SolidColorStroke, like so, this breaks the LineChart Legend:
<mx:SolidColorStroke id = "s1" color="haloGreen" weight="2"/>
<mx:LineSeries yField="v1" form="curve" displayName="Indoor Temp" lineStroke="{s1}"/>
^ With this code, The LineChart Legend stops displaying the color for that specific LineSeries, and only displays in black.
How can I override the LineSeries stroke color and persist those colors to the Legend's display?
Is this a FLEX 4 bug? I noticed in FLEX 3 examples (even on Adobe's FLEX 3 Help website) you can override the stroke colors and it persists to the Chart Legend.
I have a LineChar, with one LineSeries, on which i am drawing values ( Y axis ), on specific time ( X axis ).The problem is that i don't wanna the points which is distanced on a specific distance in time ( let say 6 hours ) to be connected.Is there a way to make LineSeries with DateTimeAxis not connecting points distanted in specific time ?
View 1 RepliesI am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
Example: Grid displaying list of towns grouped by state. At the group level ( for each state) I want to show the total number of towns in each state. Here how can i show the total number in the town column.
I 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 ..?
Here's my test application:

I would expect the mask to be applied when the checkbox is selected, and removed when it issin't. But it doesn't seem to work.However, when you change to , it works like a charm. Can anyone explain to me why?
Note: In my actual application, i'm applying this in a skin to a component that is extending SkinnableComponent which can't use BorderContainer so a solution to this would be great.
I've got some MC's in my library that have radiobuttons in them -- all of this created at design time -- and pull them onto the stage dynamically. My question is how do I get the selectedData from the group? The setup is like this: In a MC called pageOne, I have a group of buttons with a group name of Q1, Q2, etc. I pull the MC onto the stage like this:

Do I need instance names on each of the buttons and add listeners to all of them?
I have a DataGrid with info like this:
Associate AmountTimeCustomer
John Doe 29amSam Smith
John Doe 210amBerry Cooper
Bill Ace 19amSandy James
Repeating the name and amount gets redundant so I would like it to look something like this:
Associate Amount
John Doe 2
Bill Ace 1
Then when you select one, it expands to show the times and customers for the selected associate. I hope this makes sense...I am currently just using a DataGrid but I can use an AdvancedDataGrid if thats needed...I am pretty sure something like this can be done, I just don't know how.My data is in xml and looks like this:
<stat associate="John Doe" date="08/12/09" amount="2" time="9 am" customer="Sam Smith"/>
<stat associate="John Doe" date="08/12/09" amount="2" time="10 am" customer="Berry Cooper"/>
<stat associate="Bill Ace" date="08/12/09" amount="1" time="9 am" customer="Sandy James"/>
if I place a Border with width and height of "100%" inside a Group with width and height of 10 pixels the Border looks bigger than 10 pixels, why?

I have a Group that I want to do a wipe effect when it shows and hides.
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
<s:Wipe id="wipeUp" direction="up" duration="2000"/>
<s:Wipe id="wipeDown" direction="down" duration="2000" startDelay="2000"/>

The group is being hidden and shown on change of the group's visibility, but the effect doesn't do anything. When I set the visibility to false, it takes 4 secs for it to hide (delay+duration), but again, no effect.
I am trying to automatically resize the children within an s:Group. The children are another s:Group and a H:Group. Each have a percentage width of 10% and 90% each. The problem is that when one of the groups is resized (using a transition and rotation combination in the Skin), the other group does not automatically resize to fill the space?
Shouldn't Flex do this automatically? or do I have to code this?
<s:Group
id="listsGroup"
width="100%"
height="255"

I have a SkinnableContainer class called: 'GroupNavCustomContainer' that uses a skinClass called 'GroupNavCustomSkin'. The GroupNavCustomSkin is the default one Flex creates for you: (The default skin class for a Spark SkinnableContainer container). Now, I have to add buttons to the GroupNavCustomContainer dynamically from outside the class which is not a problem. However, I can't seem to figure out out to make my skin behave as a HGroup so the buttons are spaced evenly. I tried: modifying the Group container to no avail:

In Flex, sometimes when you need to clear a form you run into the problem that radio button groups seem to defy clearing: try as you might, setting selected=false on all buttons, setting selection=null on the group, doing both, doing them twice, etc., you always seem to end up with one pesky little radio button that's still selected. How do you solve this and restore the radio button group to its initial no-selection state?

I'm trying to use XML to convert the code that a Flex RTE creates to valid HTML. No problems on other HTML elements, but difficulty with unordered lists. I created a solution for moving consecutive LIs into a UL node. After trial and error, I came up with the following solution. My question is - surely there's a better way to do this?
for each (listXML:XML in xml..li) {
if (listXML.children().length() == 0) {
// list item is empty - make it an empty paragraph instead
