Flex Charting Question
Does anyone know how include a labeled 'phase change line'
within a Flex chart? These types of charts are normally used to
track behavior over time (the phase change denotes changes in
medication, etc.). Any advice would be greatly appreciated.
Yes it is possible
You need to use the cartesian chart and a secondSeries and
secondHorizontalAxis or secondVerticalaxis

Simple Flex Chart question - Plot Chart labels
I'm playing around with displaying data from WDA as charts in Flex 3.
I'm able to bind my internal table, which has 3 fields, to the plot chart.
The table looks like this
ext_id type string " bound to prjname in Flex
cost type string " bound to prjcost in Flex
benefit type string " bound to prjbenefit in Flex
These are all bound to my island's DataSource.
I have bound these in Flex and the Cost and Benefits are showing up as points on my chart. However, I can't seem to get the Project Name to display on the plot points. All I see when I mouse over the point is EXT_ID, and the values for cost and benefits.
The cost/benefit values are coming across correctly, just not the project name (ext_id) value. any ideas?
here's the Flex code for the chart
[Bindable]
public var dataSource:ArrayCollection;
[Bindable]
public var prjcost:String;
[Bindable]
public var prjbenefit:String;
[Bindable]
public var prjname:String;.
<mx:PlotChart id="plotchart1" dataProvider="{dataSource}" showDataTips="true">
<mx:series>
<mx:PlotSeries displayName="{prjname}" yField="{prjcost}" xField="{prjbenefit}" dataProvider="/>
</mx:series>
</mx:PlotChart>This is really a Flex question not an Islands specific one. I don't think the displayName properity is what you want to use here. This is the name for the entire series as it will be displayed in the legend. I think what you want is a dataTip. You register a callback for the dataTip rendering and then fill the custom dataTip quick info.
This is an example from a bar chart, but the theory is the same:
<mx:BarChart id="barChart" dataTipFunction="dtFunc" xmlns:mx="http://www.adobe.com/2006/mxml" type="clustered" width="100%" showDataTips="true" height="100%">
<mx:verticalAxis>
<mx:CategoryAxis categoryField="{SalesOrd}" dataProvider="{dataSource}" />
</mx:verticalAxis>
<mx:series>
<mx:BarSeries id="bsGross" xField="{grossAmt}" displayName="Gross Amount" dataProvider="{dataSource}" fill="{otdFill}" showDataEffect="{slideIn}" />
<mx:BarSeries id="bsNet" xField="{netAmt}" displayName="Net Amount" dataProvider="{dataSource}" fill="{rtyFill}" showDataEffect="{zoomIn}" />
</mx:series>
</mx:BarChart>
private function dtFunc(hd:HitData):String {
switch(BarSeries(hd.element).id){
case "bsGross":
return "Sales Order #: " + hd.item.SO_ID + "\n" + FlashIsland.formatNumber(hd.item.TTL_GROSS_AMOUNT) + " " + hd.item.CURRENCY_CODE;
break;
case "bsNet":
return "Sales Order #: " + hd.item.SO_ID + "\n " + FlashIsland.formatNumber(hd.item.TTL_NET_AMOUNT) + " " + hd.item.CURRENCY_CODE;
break;
return "Amount"; -
Hello All
I am in need of your help in saving a flex chart on to the server. Basically I want to export the chart to excel, as I dont find any resource for Flash builder 4, SDK 3.5, I opted the option of 1. saving chart as image to server and 2. accessing that image file in my excel
Any sample codes should be very helpful, as this is quite urgent. Thanks!The problem was, that it is not possible to see the pdf directly from transaction AL11.
I used the transaction CG3Y to move the file from the server to my desktop, and there I can see the pdf file.
Solved
Thanks for the input. -
Flex chart x-axis data spacing
hello
i am using flex chart line series and column series. i want
to display 100 data points, with different dates along the x-axis,
but i don't want all 100 points to be displayed at the same time as
the x-axis dates will not be readable. i want to have a fixed space
between each x-axis point and the user then scrolls along the
chart.
i read the API but do not see any way to add the x-axis
spacing?
also how i do put more data information, with each data point
if a mouse if placed over it, not just the X & Y data points.
thank you for any assistance.

you mentioned about using min/max values on the x-axis. That
is a good solution except i would then need to add buttons to say
,show the next 30 days.
I really want to to show 90days of data data, with say 30
days appearing at once, and the user just scrolls to see the rest
of the days data without having to press buttons for more data. Any
idea how i can do this?

Flex chart how to put distance between x-axis data

TonyI don't know what you mean then.
If you set the min and max to be a certain number of days
apart then you know the dates within those days will be displayed.
That combined with the width of the chart will define how much
space there is between x-axis points. -

Flex language questions should go in the General Discussion Forum
This forum is intended for Flex Builder questions.
Of course you can post wherever you like, but if you want
help, go where the helpers are.
Tracycan you define what goes where then?
General discussion sounds like thoughts, comments, hopes and
wishes.
Builder 2, (meaning Flex Builder 2?), seems to be the only
area for other Flex 2 questions.
I don't mean to be wise here, but I personally don't
understand what a "builder 2" question is if not those that deal
with flex 2, such as those posted here. I want to post my questions
where they should be so that I might find help, so maybe the forum
labelling should be re-considered or better defined. -
Flex chart restarts on tab focus in firefox
I have plotted flex chart inside div element. It shows up correctly but when i go to another tab in firefox and comes back then flex chart restarts. Also i have seen it happens inside dojo tabs also.
Anyone has any idea why chart restarts ? How can this be avoided.
Thanks,
ZoozThe author of Custom New Tab says this will be in the next update of the extension.
If you don't want to wait for the approval cycle on the Add-ons site, you can grab it from the Versions page:
https://addons.mozilla.org/firefox/addon/custom-new-tab/versions/
<s>Note: I have not tested it myself.</s>
<u>Version 1.9 worked for me. See screenshot regarding how the Options dialog works for the updated extension.</u> -
Copy and Paste Flex chart to Word Document
Hi , I'm a newbie to Flex and was wondering if anyone knows
if it possible to use the right click button on the mouse to copy
and paste a Flex chart to a Word Document? Any help would be
greatly appreciated.
thanksHi,
Simply let a IE or FireFox window display your Flex chart,
and hold [Alt] and press [PrtSc] in your keyboard, Then, paste it
into Word or Paint to be edited.
Have fun!

Convert/Export Flex chart to MS Word
Hi All,
Please let me know how to Convert/Export the Flex Chart to MS Word...
Please send the related links or samples if you have.
Thanks in advance.
Regards,
Seshadri Babu.GWell, "used to..." is not a good business case.
They don't need to receive reports anymore, they can view them in the portal as needed. Viewing in Word is functionaly about the same as viewing in Excel if "receiving" is the preferred method for them.
Having reports in PDF is better if they want to print.
Or they can use Crystal reports as a last resort.... I think those might export to word.
Webi is on-demand, ad-hock reporting, that's what's it for. Export to other formats is a secondary function. -
Hi,
I've put together a simple test app that pulls data from blazeds and inserts the results in a PieChart defined in mxml. However when I try to create the same chart in AS the chart doesn't show up. I suspect that it is perhaps related to the sequence of how things are initialized? but I'm not sure
Here is my code. I've created 3 charts. The first (mxml) chart is the one that works fine. The second (AS) is my attempt to recreate the mxml chart in AS and it does not work. The third is a sanity check of another test AS chart just to see if I can actually make an AS PieChart and it also works fine.
If anyone has any insight it would be much appreciated.
Thank you,

This suggests that your HTTPService result is coming back in
a format where
you can't just get the properties off of it. You may need to
set the result
format to e4x, and since it is rss you may need to use one or
more
namespaces.
