I'm making a mobile application with a bargraphs in it. I'm using Flash Builder 4.6 and Flex SDK 4.6.0.
In my appication I'm using the builtin Bar Graph from Flash Builder. Is there a possibility to zoom and scroll with this chart. Remembder that it is a mobile app (iPad) so it needs to work with gestures.
I'm trying to create a custom view (one that is not 100% listview, for example), mix and matching images and labels.One issue is that when the label overflows greater than the screen height, the rest just gets off. I had assumed scrolling or touch-drag scrolling would be automatically enabled? How do you enable the touch-drag scrolling that happens naturally in list view?
View 1 RepliesI have a spark datagrid on a mobile application, I set the
interactionMode="touch"
and the dataGrid scrolling is good, I got some problems adding a selectionChange eventListener to it, because scrolling the dataGrid will automatically change the selection and instead simply scrolling it, the function binded will start...
How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
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 trying to make chart which is combination of bar and line chart using Flex Charting API . Here x axis would be common and y axis would be different. note that y axis got different range of value one is % and other is amount. Any one got idea how to make this chart. Here line chart would be staked on top of bar chart . The line chart and never over laid or drawn on top of bar chart.
View 1 RepliesI would like to move (right or left according the current view) between 2 views when I move my finger on the mobile screen; for example with Google+ mobile application, in profil section, you can change the view just on move your finger on the screen, and the offset and the moving speed must be checked before change complete view.

View 1 Repliesi have a 400x400 image i want to zoom it by 200 percent whan it zoom i need vertical and horizontal scroll bar to show it.
View 3 RepliesI need to be able to zoom in on my image, but I cant get it to work properly. I've got an Image showing my content, and it get it's content from a BitmapData. The BitmapData is full-res, which is 2880x1620, and the Image is scaling to fit my window. The SmoothImage is the same as Image, but with smoothing added.
<me:SmoothImage id="imageFull" visible="false" width="100%" height="100%" />
How would I go about zooming this image when I scroll my mouse? This is the code I have, and it does change the scaling factor. But since it's set to fit my view, nothing happens...
public function videoBufferWheel(event:MouseEvent):void{
myZoom += (event.delta/10);
if(myZoom >=1){
imageFull.scaleX = myZoom;
imageFull.scaleY = myZoom;
}else{
myZoom = 1;
}}
Okay, I will begin be mentioning I am pretty new to flash, however I have a decent amount with other programming languages like c++, c#, vb, pl/sql, coldfusion, and some others so I feel comfortable jumping right in.I do understand a lot of the basics in flash, but I am starting a project in as3 that I am having some issues with.(I would attach the fla, but it exceeds the file size limit with the png file attached)

//import slider classes

Using flex / air 2.6 working on an Android device, I am using a canvas with a TransformGestureEvent for zoom in on a map. The listening of the efect is working ok, but I canīt seem to find the information on wether the user intended zoom in or zoom out (fingers getting closer or getting apart).I expected the intention of the gesture to be identifiable with the offsetX and offsetY properties of the event, as you will do on a swipe gesture event. But I always get 0 for both properties, no matter how I do the gesture in the device.How can I know if the fingers getting closer or getting apart in a gesture zoom event?

View 3 RepliesHow can I Create an animated Bar Chart or Line Chart type of component in flash programmatically, which should depends upon an incoming XML data, the chart should have the basic criteria like, Chart Label, Item Tooltips, background grids (without using any image). There also needs an ability to change the data which should reflect the chart as well.
View 1 RepliesMy 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?
Flex 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,
I have a dynamic ArrayCollection that will contain a unknown number of objects of type MyObj:

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 ..?
Is it possible to restrict flex bar chart y-axis count?I have a very big name coming in my y-axis and i want to reduce or restrict it to 5 characters and on rollover i want to display it in full.

I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.

There is many answer regarding the speed of the mouse wheel but no answer concerning the spinner itself.
I 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.
In Flex how can I set a custom name (string) for the X axis and Y axis titles of a chart?

I want to make a scope wich can zoom in on button click and go back to previous stage (zoom out) also by clicking a button.Now i made it work for zooming in (when i click my button it zooms) but when i want to zoom out everything i tried didn't work .Here is the code:
//button for zoom in
zoom.addEventListener(MouseEvent.CLICK,glassMove);
function glassMove(event:MouseEvent):void{[code]..............
i've made a button that zooms into a movie clip on a rollover, but it on moves it a certain amount each time you rollover the button. code below:
on (rollOver){
_root.Mypic._width += 5;
_root.Mypic._height += 5;
}
wot i want it to do is to continue zooming in for as long as the mouse is over the button, is there anyway i can change the code to zoom in at the same amount but do it continuously until the mouse is moved off the button. Also is there anyway that i can set it so that the zoom stops at a certain percentage, i.e. it only zooms in so much and then stops. What i mean is that the user can zoom in but the picture will only zoom in to say 200% of the original size.
