[flexcoders] Re: Question?? Best method for plotting a Moving Average
I'll vouche for ta-lib as well. I used it in an excel trading/chart app I made
years ago.
My approach for the ticker data array would be to use a for..loop instead of
hard coding. That way you could adjust a few paramaters.
When it comes to technical indicators, I prefer making the calcs on the server
side and then having the data available to be plotted
passed/requested/whatever. The reason being I can use that data in whatever
client I want versus trying to learn different ways of doing the same thing in
different clients.
Another approach you might want to look at is using a charting library that has
built in functions for the traditional indicators. I've used ChartDirector
from ASE in multiple clients and multiple platforms. http://www.advsofteng.com/
You could write up your charting section in whatever and then bring it into
flex as an image. ChartDirector is also open enough that you can program custom
indicators into as well which is something I've done quite a few times and is
what really sold me on the product.

There's a lot more than just a moving average and bollinger bands there but
those are parts of it. In order to get this data, we first tapped into a
feed which you have to pay good money for. I believe we are using NxCore
which I think is a DTN product. You might look into that but I know there
are others as well.
For the data, we pass data into a java library called ta-lib:
http://ta-lib.org/
It has methods for moving averages, deviations, etc. We found that the
calculations for our app were simply too intense to be done on the client.
But, we have 5-7 years worth of data that we are looking at for calculations
so you might not run into the same bottleneck we had

[flexcoders] Detect if any of the Items on a List are Selected - thought it would be easier.
The only property I could find, from the Flex docs, that tells you whether your
List control has anything selected is: isItemSelected().
And this takes a parameter that refers to a specific item. So before my Delete
button handler, I check if any item is selected with the following:
private function deleteHandler() {
var bDoesNotHasFocus: Boolean = true;
var len:Number = projectList.dataProvider.length;
for (var i:int = 0; i = len - 1; i++) {
if (projectList.isItemSelected(projectList.dataProvider[i]))
{
bDoesNotHasFocus = false;
}
}
if (bDoesNotHasFocus)
return;
// the code to delete
}
Is there a better way, anyone?

RE: [SPAM] Re: [flexcoders] Can't bind XMLListCollection to Datagrid
You have a namespace issue.
You might be able to use the namespace in the dataField, like this:
dataField=datas6::Employee LastName, but I am not sure that will work.
But I would declare a namespace and use that. I don't have any code handy,
but search for namespace and you will find examples and more info.

I am stumped with a problem in my DataGrids itemRenderer. I am using a regular DataGrid and my column has a renderer that extends UIComponent and not DataGridItemRenderer. In my renderer is a UITextField that has wrapping turned on. The user can expand and reduce the width of the column, and as they do I have a function that truncates the text if there is not enough room in the column to display it in 4 lines or less within the visible space of the resized cell. I use the UITextField.numLines property as my indicator. This works great when I expand the width of the column. I doesn't work when I reduce the width of the column by making the text go from, say 2 lines, to 5 lines. When I roll over the row, the UITextField updates its numLines property. Any ideas about an event I can listen for on the DataGrid or ItemRenderer, or a method to call on the UITextInput to make it update the numLines property? thanks! Dustin
