Are you using a DateTimeAxis? Have you set any of the properties on DateTimeAxis like: dataUnits, dataInterval, labelUnits, interval, unitSize, padding, etc? Not saying any of those properties will address your problem, but not a bad place to start. Sunil

Subject: [flexcoders] FLEX defaut xml parser issue with Auto Exponential

cusipvalue7898778E345/cusipvalue
if you see above xml tag value, that is having E char. this E is causing the
issue.
above value(7898778E345) displaying as Infinite When i display this value on
flex grid. the reason is this value has E. so the flex parser is implecitly
convertion is faling.
7898778E345 = 7898778 * 10 Power of 345 = too big value = Infinite.
Is there any way to instruct flex defalut xml parser to stopping auto
conversion into expaning exponential value?.
Any help is appriciated.

Like growl, I wanted to bring out a number of rectangular notification windows that fade out after some time. There are 3 ways I can see this being accomplished: 1) Open new NativeWindow for each notification 2) Open one transparent nativeWindow add children to it calculate its size based on the number of children being added (notifications), and then place the window appropriately on the screen's edge 3) Open one transparent nativeWindow to the size of the screen (resolution), and add notifications to its right edge. Is there one implementation over another that may have better performance ? #2 seems it may since it creates one native window of the exact size it needs, but its the most work. Any thoughts ?

childCanvas.percentWidth = 100;

childText.percentWidth = 100;
parentCanvas.addChild(childCanvas);
parentCanvas.addChild(childText);
Let the childCanvas be 100% of the height of it's parent. The parent container

[flexcoders] Re: Idiots guide to crossdomain.xml
If your SWF is hosted on server A, and it needs to access data from servers B, C, and D then you need to put a cross domain policy file on servers B, C, and D that permit access from server A. Note, these servers (A,B,C,D) are different servers ... the names are not aliases. It kind of sounded like one of your host names is an alias for the other. The cross domain policy file you deploy on each web server should allow access from server A, since that is where your SWF is hosted: allow-access-from domain=serverA.domain.com / Also, newer versions of the Flash player will complain if your cross domain policy file does not have a site-control tag. Here's a simple one I use: site-control permitted-cross-domain-policies=master-only/ Which means there's only one policy file for my site.

[flexcoders] Re: Plotting values equal to Zero on the Line Chart
Hi, When there is no data for a given day, are you representing this with an actual 0 (zero), or a null value? My experience is that when the data is 0, the chart plots data on the axis and often it looks like there is no value at that point (because the chart line is plotted on the axis itself). Enable dataTips for your chart and mouse over a point with no data, does a tool tip appear? I would expect no tool tip when the value is null. The way I understand it, interpolateValues is only used when the data is missing (null), not zero. So it sounds like you have no value, not a zero value :) Sunil --- In flexcoders@yahoogroups.com, David Unger [EMAIL PROTECTED] wrote: I'm relatively new to flex, and I have been using the line charting control to display a line chart of how many times a media type on my site has been accessed on a daily basis. The problem is that any time I have a value of zero for any one day there is a break in my chart. If I set interpolateValues to true on each of my line series, it just connects the line to the next day with a value, instead of connecting to the a value of zero on the X axis. I have searched all over to find an answer on how to plot values of zero on the access and have come up empty handed. Is there a straightforward way to do this? Am I missing something?
[flexcoders] Re: decrementing the x axis on a chart
I concur, massaging the data is perhaps the way to go. Another option would be to just generate your chart and rotate it 180 degrees ... but this might have other issues (i.e. upside down text, or data-tips, etc.) I did a data massaging approach here: http://blog.sunild.com/2008/08/inverting-chart-series.html Two important things to note: 1) I used the dataFunction property of the AreaSeries (LineSeries in your case) to massage the data. In my case I negated the value of each data point. This modifies the data to be plotted, not the actual data itself. 2) I used the labelFunction property of the LinearAxis to format the labels. So even though my data was plotted as a negative number, the axis labels show them being positive. I think you can achieve what you're looking for by doing something similar. Sunil --- In flexcoders@yahoogroups.com, Tim Hoff [EMAIL PROTECTED] wrote: HI, You're goung to have to massage the data to get your desired result.

[flexcoders] Re: flicker problem with zoom effect
I think this depends on how you've setup your effects. For example, I had funny problems w/effects that were part of view state transitions. This happened because I neglected to specify where in the transitions that the add child/remove child actions should have occurred (b/c I didn't use AddChildAction or RemoveChildAction). Might be easier to pinpoint if you post your code or a simple example.

[flexcoders] Re: Issue with runtime adding of axis labels in DateTimeAxis
For what it's worth, I do this all the time with charts: call removeItemAt(0), and then call addItem( newDateHere ) It works well. The oldest date is removed from the beginning of the array collection and a newer one is tacked on to the end, the chart updates automatically. No need to call any other methods (like refresh). As suggested a code example would help... Sunil --- In flexcoders@yahoogroups.com, Arun Shankar [EMAIL PROTECTED] wrote: dataprovider which is an ArrayCollection for the dateTimeAxis is bindable one. My code looks something like this ArrayCollection.removeItemAt(0); ArrayCollection.addItem(date object); ArrayCollection.refresh(); i believe the first item would get removed and the new date object would get added to the end of the list and the call to refresh() should ultimately makes the chart to redraw with the new change in the collection. i guess flex caches the dateTime axis labels which is ultimately causing this problem.

[flexcoders] Re: Displaying a date in a line chart
Hi, Here are two approaches I've used: 1) Using a DateTimeAxis: If the data representing your dates is in the format that can be easily converted into a Date object (see docs for the Date constructor), your DateTimeAxis will understand the dates implicitly. Otherwise, you need to write a parseFunction (see DateTimeAxis docs) so your data can be converted into a Date object. Then as Tom suggested, use the labelFunction property to specify a function that will return a properly formatted date string ... in the labelFunction use a DateFormatter to print the dates in the UK format ( or just use the Date object's toLocale method). 2) Using a CategoryAxis: Instead of using a DateTimeAxis, consider using a CategoryAxis. This approach is similar, except now you don't need to worry about writing a parseFunction. Just write a labelFunction as described above. The CategoryAxis won't deal with dates as nicely as DateTimeAxis, but it works nicely for fixed date ranges (it wouldn't be so good for doing a Google Finance type of chart where you can change time frames of the chart). Check out the docs for the labelFunction and parseFunction properties of the DateTimeAxis (or CategoryAxis). They show the function signature that's required, from there it's easy :) Sunil --- In flexcoders@yahoogroups.com, Tom Chiverton [EMAIL PROTECTED] wrote: On Wednesday 10 Sep 2008, gr33neye501 wrote: The data is a collection of Date objects, and is displayed in US format.

[flexcoders] Repeat SSL certificate warnings in AIR app on Windows
I'm working on an AIR project that uses a Timer to fetch data w/an HTTPService.
The UI
for the appliance uses a self signed SSL certificate.
As expected, the AIR app throws up a warning dialog about not trusting the self
signed
cert. But I get different behavior on this between Windows and Mac OS:
- On the Mac OS X 10.5, I am warned only once about the cert.
- On Windows XP, I am warned each time an HTTPService is used (when
authenticating
w/the appliance, and each time the Timer triggers an update).
I know I can install the certificate in the browser to make it trust it...
but the average
user of the appliance wouldn't necessarily know this.
This seems like a bug, any thoughts or suggestions would be greatly appreciated.
Here's a really simple app that exhibits this behavior. Clicking the Reload
button on Win
XP generates the cert warning each time, but not on Mac OS. Sorry, the URL
below is for a
private IP ... the example is so simple, you don't need to run it anyway :)
