In flex charting, I want to draw something like "reference lines" which are related to specific series, therefore these lines are not independent series and should not be shown in legend. Is it possible to exclude some series from chart legend?
View 3 RepliesI would like to be able to specify the placement of a legend for a linechart. Currently, it continues to appear to the right of the chart. I have tried playing with the width/height of the chart to no avail... Putting the legend before the linechart in the mxml causes it to appear to the left. I can't seem to get it appear at the bottom though. I can't seem to find any good examples for this. They don't seem to specify anything but the legend usually shows up below the chart, I can't seem to do it.
View 1 RepliesMy Flex chart has code that creates a legend from each data series. Currently, I have the drawLegend function execute when a button is clicked.
I am trying to get the legend to draw automatically but I am having trouble determining when to call the drawLegend function. Users click on an 'Update' button which retrieves data. I want the legend to get created after this, without the users having to click on another button.
I have put my drawLegend function in several places (ResultHandler, afterEffectEnd(for chart animation, etc.) and nothing works.
Sometime after the series has been added to the chart and after the series animation ends, the legend can be added.
How can I trap this point in time and call my function?
Below is the code I used to create the legend. Note that even though the code processes each series, I noticed that the Fill color is null if it is called too early.
private function drawLegend(event:Event):void {
clearLegend();
// Use a counter for the series.

I have a LineChart continaing 6 lineseries. I should be able to pass parametrers to server using HTTPservice. But then the returned XML may contain information for a single line series or for all the lineseries. The problem, if we have a value for a single lineseries , the legend should contain also only one item and similarly for multiple items. [code]...
View 1 RepliesHow can i make the Legend Horizontal or Vertical.
View 1 RepliesI'm creating a custom legend using legendItemClass to highlight each item when the user rolls over, remove it when they roll off and highlight it a little differently when they click. That all works just fine but I also want the pie wedge to explode out when the user click. I have the piece of code but it requires a LegendMouseEvent. I'm also thinking I may be able to re-write the code if I could get the displayName but I'm a loss with that as well. Here's what I have:
Legend:
<mx:Legend id="legend" width="100%" direction="vertical"
labelPlacement="right" markerHeight="10" markerWidth="10"
legendItemClass="CustomPieLegendItem"[code]......
Instead of having legend scroll, I want to make it multi-columnar. I will fix the height of legend, and if the items exceed the legend, then it should extend one more column to display extra legend and so on.

View 1 RepliesI am implementing a LineChart in FLEX 4. I have the chart working well except I do not like the default colors and cannot use them, as they do not relate to my data very well. For instance, Orange is not a great default color for my data column "Outdoor temperature". I would rather override it and use a green color if possible.
When I explicitly specify the SolidColorStroke, like so, this breaks the LineChart Legend:
<mx:SolidColorStroke id = "s1" color="haloGreen" weight="2"/>
<mx:LineSeries yField="v1" form="curve" displayName="Indoor Temp" lineStroke="{s1}"/>
^ With this code, The LineChart Legend stops displaying the color for that specific LineSeries, and only displays in black.
How can I override the LineSeries stroke color and persist those colors to the Legend's display?
Is this a FLEX 4 bug? I noticed in FLEX 3 examples (even on Adobe's FLEX 3 Help website) you can override the stroke colors and it persists to the Chart Legend.
I'm trying to build a webmap application in flex. For this, I've got a fxg-file which represents the maps. It's in a also there are some elements, like POIs, text etc., in this group. I zoom the with scaleX and scaleY, this works just fine for the map. But the problem is: All children zoom also. I don't want this. They should stay the same place on the map and the same size.

I've got a Flex TileList which has an ArrayCollection as its data provider. The ArrayCollection is used elsewhere in the application so modifying the base data is not possible.
There are two items at the start of the collection (indices 0 and 1) which I don't want to be rendered.
Is it possible to exclude these items from the TileList rendering?
Using Adobe Flex Builder Pro stand-alone, how do I filter or exclude some files in my project source folder from being copied into the bin-debug folder during a build? Flex Builder is based on the Eclipse platform IDE, this could be as much of a question about Eclipse as it is Flex Builder.
View 2 RepliesI have a flat data array that comes form a remoteobject, I want to group whatever is to be grouped, but leave single items (the ones with no common data with anything else) alone and without grouping, it's annoying to open each node only to find there's just one item inside, so there was no need to put it inside that group anyway. I can't find any reference and I don't know if getting the hierarchicaldata out of the groupingcollection and then iterate thru it would be any good, sounds like a lot of duplicate work.
View 2 RepliesI have a Flex LineChart which contains three series:
two LineSeries
one ColumnSet
Has anyone seen or heard of a way to set the dataTipRenderer on a per-series basis? You can only override it for the entire chart and I would prefer to not have to overlay multiple charts just to achieve this effect.
There is probably no way for this but does anyone know a method of excluding certain functions from a build by use of a meta tag and or compiler option?I want to expose some functions for testing but not have them bloat the application on production. I could create separate testing classes and test for a complier directive or option and only load them if necessary but I like the idea of having the test function on the actual object (in the class).

View 2 RepliesI want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?
View 2 RepliesI have an air app that collects live data from a user's action and graphs it.It records data every second and charts it on three different line series from the same array collection.This works out great at first, but it gets worse and worse as time goes by. When it gets close to an hour it's almost unusable.I'd like to be able to add a point to the graph and have flex JUST draw the new point and not invalidate the whole series and redraw it. Is this possible? I'm willing to override something to make this work.My last ditch effort is to take the average of 5 or 10 points and only adding those. This will still work poorly when the user is going for 3 hours or so, but I can't think of a better way.

I have a column chart that I made using Adobe Flash Builder.
I'd like to be able to dynamically add (or remove) column series.
I have a LineChart that contains multiple series, both LineSeries and PlotSeries, and I have a custom dataTipFunction set for the chart. However, I only want data tips displayed for line series, not the plot series. I have tried returning null from my format function, but that just displays an empty box. I have also tried disable mouse events on the plot series (by setting both mouseEnabled and mouseFocusEnabled to false), to no avail. Is this even possible?
View 1 RepliesI am creating a chart using mxml. The mxml tags only create a chart with a horizontal axis and vertical axis. My result event handler has actionscript code that loops through the xml result set and creates all the series (line series and stacked bar). This part of the code works fine. Now I need to use the functionfill function to set individual colors to each series. All the examples I have found call the functionfill from within an MXML tag, like so:

I'm trying to use a custom Text component to show a series of comments. I got the original idea from:
[URL]
I've got the base case working but I am stuck with 2 problems I cant seem to figure out:
Since I am drawing around the text, the actual height of each bubble is greater than that of the Text field, as a result, the last bubble is always chopped off. I have tried explicitly overriding the height getter, and adding some padding, but I cant seem to get it right. You can see an example here: [URL] In my layout, I have 2 VBoxes (one nested inside the other). The first vbox shows a form where the user can enter a comment, and the second box has all the comments. In order to ensure that the scrollbars only show up on the second box, I set minHeight="0" on the nested VBox, but then for some reason, some comments' text is shifted to the right. You can see an example here (look at the first comment): [URL]
Rather than posting the code here, I've provided some links:

I have a line chart with a column chart as a secondary series. When I roll over the line, the datatips appear. However, if I move the mouse to a spot where a column appears while still on the line, the data tip item appears for the line AND the column. How do I get it so that I only show datatips for the line but not the column?

I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me. So I am going to try to ask my question specific to what I need to do.I have a set of points that describe a non-straight line (sometimes a closed polygon). I have a rectangular "view" region. I need to determine as efficiently as possible whether any of the line segments (or polygon borders) pass through the view region.
I can't simply test each point to see if it lies within the view region. It is possible for a segment to pass through the region without any point actually inside the region (ie the line is drawn across the region).Here is an example of what I want to determine (red means the function should return true for the set of points, blue means it should return false, example uses straight lines and rectangles because I am not an artist).
Another condition I want to be able to account for (though the method/function may be a separate one), is to determine not just whether a polygon's border passes through the rectangular region, but whether the region is entirely encompassed by the polygon. The nuance here is that in the situation first described above, if I am only concerned with drawing borders, the method should return false. But in the situation described here, if I need to fill the polygon region then I need the function to return true. I currently do not need to worry about testing "donut" shaped polygons
Here is an example illustrating the nuance (the red rectangle does not have a single vertex or border segment passing through the on-screen region, but it should still be considered on-screen):For the "does any line segment or polygon border pass through or lie on screen?" problem I know I can come up with a solution (albeit perhaps not an efficient one). Even though it is more verbose, the conditions are clear to me. But the second "is polygon region on screen?"PS I have a function for determining line intersection, but it seems like overkill to use it to compare each segment to each side of the on-screen region because the on-screen region is ALWAYS a plain [0, 0, width, height] rectangle.

View 1 RepliesI have a problem with the cartesian charts in the Adobe Flex SDK 4.5 and 4.5.1. Perhaps it's a bug, because it's not in the SDK 4.0, 4.1 and 4.6. Or it's just a problem of my code.
I made a little example project to range over series data in a CartesianChart (Line/Area/Column/Bar), a little bit like the google finance chart. When I add all series to the chart, the problem didn't occur. Only when I have multiple series and remove one or more series and than range over the data, the series data get compressed:
Chart image It seems like the horizontal axis didn't change or didn't get an update that the chart data changed, when I range over the current data.

Had someone the same problem or has an idea how to remove a series in another way?
I have the follow class :

The new series name appear on the chart, but the data doest, and the chart always remains blank.
