Flex :: Does Fire An Event After A Chart Is Rendered In UI
Sep 7, 2011I am looking for an event which is fired (if any) after a chart is rendered (visible in UI) in Flash, we are using Flex SDK 3.0. We have to capture the screenshot after the chart is rendered, current implementation adds a huge delay in update_complete event callback, this is slowing down the whole job of generating images. I tried to use EXIT_FRAME event, but this doesn't seem to serve the purpose.

Flex :: Draw Line On Top Of Column Chart
Aug 3, 2010Apparently, it is not possible to have a chart with several independant horizontal axis. What I am trying to achieve is :
Display a bar chart, organized by any category
Overlay a line (actually a single horizontal line) on top of it (to display some sort of threshold)
I tried doing the following :
[Bindable] public var columnsDataProvider : ArrayCollection =
new ArrayCollection([{"Category" : "Cat1", "Value" : 10},
{"Category" : "Cat2", "Value" : 20}]);
[Code] .....
This is the closest to what I want, except that the line does not start span all the graphs vertically (it is drawn only between the two columns of my bar chart). Is it possible to define a completely independant horizontal axis? I also tried drawing directly on the canvas, but the canvas.lineTo() method only works in "data" coordinate; I would need something that works in "chart/canvas/absolute/whatever" coordinates.

Flex :: Line Chart Leaving Gaps In Data?
Dec 6, 2010I have a Flex line chart where I allow the user to change the y axis ranges.

Actionscript 3 :: Draw Line Segment On Chart Using Screen Coordinates?
Jan 16, 2012I'm new to Flex, I've tried to do this using a CartesianDataCanvas inside backgroundElements in mxml, then using ActionScript to draw lines on the data canvas using moveTo(x1,y1) and lineTo(x2,y2), which draws a line between (x1,y1) and (x2,y2).
The problem with the above method is the tick mark length is a function of the chart area (which depends on the browser window size).
What I need is a method that:
(1) starts at a data coordinate (e.g. moveTo(x1,y1) works fine for this)
(2) draws a line to a screen coordinate (e.g. lineTo(x_screen, y_screen) where x_screen and y_screen are screen coordinates).
Is there anything that can accomplish this in Flex/AS3?
Alternatively, could I use screen coordinates for both steps above? If so, how to convert between screen and data coordinates? For example, is the upper right corner of the screen always a fixed data coordinate that I could reference is creating such a conversion?
Alternatively, could I save a five-pixel line in Illustrator and simply paste that image in the chart somehow? If so, how to paste it exactly at a data coordinate?

Flex :: Top Horizontal Grid Line On Column Chart Is Not Applying Style
Oct 21, 2010I have a Flex Column Chart that has a range of 0 - 6 on the y-axis. I have added the following block to change the default colour of the horizontal grid lines to black.
<mx:backgroundElements>
<mx:GridLines>
<mx:horizontalStroke>
[Code]....
This works fine for all but the horizontal grid line at the top of the chart (at y=6). If I change the maximum value for the y-axis to something different then this new max doesn't have the formatting applied (but all the others do).
how do I get the top line to be black like the rest of the grid lines?
