Flex :: Extending X-axis On LineChart For Unknown Future Data?
Jul 13, 2010
How do you display data on a LineChart that cuts off where there is no more data? For example, if I am showing a chart of company revenue for 2010, the chart should only show up to July now (with August and forward on showing no data). This would make the line in the line chart break and dissappear off at about midway through the year.
why the data points on the LineChart don't line up with the corresponding tick mark / horizontal axis label? See adobe's example (at the bottom of the page):[URL]See how the data for 7/28/05 is to the right of the 7/28/05 tick mark / label?
i am working on a line chart on flex which enable me to view the progress of data according to the year. I have tried using a slider to filter but it doesn't seemed to work.
and my aim ise to create a Slider which can change starting and ending of the graphic, it is like what is showing in figure 6 in this website and here the MXML codes;
<Projectlist><Project> <ProjectName>Alcoswitch - ToggleSwitches </ProjectName> <ProjectStatusname>Planning</ProjectStatusname> </Project><Project><ProjectName> Transverse Wedge</ProjectName> [Code] ..... My X-Axis shows multiple values of In-Progress, but I just need one. Is it possible to represent such relationship using BarChart. Any other Flex chart is Advisable.
I'm making a chart where the x-axis needs to have dates and y-axis names. The lenght of the bar is longer when the date is later. But I want to stack multiple bars on eachother. for example This is the code I have so far
I've made an user login, working with php and MySQL. When the user logs in, he can see all of his details, loaded from a database. Here he can press a button to change this content. After changing it, he needs to press the "save" button to load the new data into the database. But everytime the user presses the save button, it's adding an extra line to the data into the database, which results in an error of displaying the data. Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'google_verify.php' (include_path='.:/usr/local/lib/php') in Unknown on line 0
I have a line series in a linechart and a slider that goes from 0 to 200. When I now move the slider, I want to have a dot appearing at the chart so when I move the slider to 150, there should be a dot where the x-coordinate of the chart is 150.
I have a LineChart with a DateTimeAxis as horizontalAxis and a maximum set. If a point is beyond the maximum date, the whole segment will not appear. Yet, is there a way to make it appear until it reachs the border of the chart?The code here :
<?xml version="1.0"?> <!-- Simple example to demonstrate the DateTimeAxis class. --> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
how can i create mx:LineSeries dynamically depending upon array collection values. Now only 4 line series is there but some times i have to show more as per the array collection values change ex: if one more status HoldProject added to array collection?
Is there a way to break the line in a line-chart, if the gap between 2 values on the x axis is bigger then a given value? For example there are 20 values but the first 13 are close to each other on the x axis and should be connected with a line, but the other 7 are a bit far from these and should be connected with another line. The type of values are the same.
I have a line chart with 4 line series with diamond, circle, box and triangle as item renderer for the plots for these 4 line series.Now my requirement is I want to show labels for the plots in the chart. It should be like this : I tried with some item renderes but not getting it correctly since I want to use the circles and triangles to render the plots.
I have a Flex3 LineChart component using an CircleItemRenderer and the datapoints are being cut off because they are too close to the edge. Here's what it looks like: [URL] As you can see, the circles on the left and right sides are being cut off. How can I make the LineSeries area, plus the horizontal labels, narrower so it fits in the chart area?
I'm doing some line charts in my Flex application, and I need to draw segments of those line chart in different color. Does anyone have an idea how this could be achieved? For instance, if I have a code like this (actually, I have given this trivial example for simplicity (the problem is the same)):
I'd like to put a label to each LineSeries on my Flex LineChart so it will be shown next to the line (along it). Any relatively easy way to archieve that?
I have a line chart in flex with a dateTime axis. I am setting the dataprovider to that linechart via actionscript. The graph gets drawn. The problem occurs when i assign a null to the dataprovider so that the graph becomes empty.
Actual code looks similar to the code below :
var actualValues:XMLList=flowChartDP.upFlows; var localSeries1:LineSeries = new LineSeries(); localSeries1.dataProvider = actualValues;
I need to create LineChart that display datetime points, for example:
public var stockDataAC:ArrayCollection = new ArrayCollection( [ {date: "2005,7,27,22,15,30", close: 41.71}, {date: "2005,7,27,22,16,30", close: 42.21},
I need to be able to animate a LineChart based on the SeriesInterpolate data effect (I will have an Array of dataproiders). I want to have a "Play" button that will:
initialize the LineChart with the first dataprovider in the array start the animation and wait for the animation to finish before loading the second data provider repeat the process until all data providers in the Array are loaded
I am using FlashDevelop to develop flex applications and wanted to paint a LineChart in a panel. I used an example of Adobe itself to be found here. When I compiled it FlashDevelop showed the following output file type was not found or was not a compile-time constantFor Both LineChart and AreaChart.Can someone tell me why this happens? I also tried it in the code by importing mx.charts.LineChart, my code completion found the classes but when compiling the same error occurs.
I'm new to Flex. I've been graphing multiple series in a line chart where all of these series are the same length. Now I need to plot new data and each series has a different length from each other. The question is how to modify the following code to do this.
The initApp() function is called at the start of the program, and it calls function genData() to generate the dataSet used for plotting in the LineChart.
public function initApp():void { // Initialize data provider array. dataSet = new ArrayCollection(genData());
[Code]....
Can someone recommend how to place array1, array2, array3, and array4 into x1, y1, x2, y2 (respectively) when the length of array1 and array2 do not equal that of array3 and array4? Or, equivalent outcome.
I'm assuming everything has to come in through dataSet, but I wonder if it's possible to simply reference array1 (etc.) directly from <mx:LineChart ...> or <mx:LineSeries ...> somehow, to avoid wasting memory on an unnecessary array (e.g. dataSet).
I 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:
^ 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 wrote a function to override y FLEX LineChart's datatips because the default datatips were ugly and rather boring.I finally set the style I wanted but am now having some problems removing un-necessary tags from being displayed in the custom datatips.For example, the datatips now display things like this:
"<b>Humidity</b></BR>2010-07-05T00:15:00"
I can always perform a "Replace()" to remove those break and bold HTML tags, but that seems really un-necessary and anti-development.I am using this to set the dataTip's label text:
var hd:HitData = value as HitData; var item:LineSeriesItem = hd.chartItem as LineSeriesItem; _xAxisText = String(hd.displayText + ' ' + item.xValue);
I want to extend the dictionary class. Everything works so far except that in some of my methods that need to reference the dictionary's content I make a call like:
this[ key ]
It doesn't like that. It just tells me that there's no property 'key'. Is there a way to way to access the data within this class?Also, I'm using an integer for the key.
Edit: I've found that the same behavior happens when you extend Array.
var myArray : Array = new Array(); trace( myArray[ 0 ] ); var myArrayExtender : ArrayExtender = new ArrayExtender();[code]....
Where in this case, myArray returns "undefined" and myArrayExtender throws error 1069. ArrayExtender is an empty class that extends Array and calls super() in the constructor.
I have a LineChar, with one LineSeries, on which i am drawing values ( Y axis ), on specific time ( X axis ).The problem is that i don't wanna the points which is distanced on a specific distance in time ( let say 6 hours ) to be connected.Is there a way to make LineSeries with DateTimeAxis not connecting points distanted in specific time ?
I have a Hgroup that contains of four panels. Sometimes it happens then when users open it the panls have a unknown width even bigger than the window resolution.
I looked at different flash chart software (free and commercial) and could find only one that supports the feature I want: map my dataset on the predefined X axis. Let me give an example.
Let's say my X axis is time. The time is represented in hours. So let's assume my X axis has last 24 hours. Now the data I have in the database contains data coming every 50 minutes. My goal is to have a chart that will show this data. The point on the graph will not correspond to X axis values one to one.
The simple solution (and all charts support this) is to set X axis resolution to 1 minute and only show "ticks" on A axis every hour. Assuming that chart supports "null" values (and most of them are) - it works fine as an idea.
The problem is that in this case (for all of the charts I know) I have to provide XML/json/CSV as a source of data that will contain 24 hours * 60 minutes points of data, with only ~29 (24 hours, every 50min) containing meaningful data. This puts a stress on 1) database, 2) more traffic 3) makes chart less responsive.Are there any flash graphs that will accept a dataset of ~29 values and map into 24 points on X axis.
I would like to compile my flex application with a services-config.xml file. However, I am forced to supply a context.root. In my setup, the context root (context path) isn't known until my .war file is named and dropped into the webapps directory.
