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.

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.

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 also tried it in the code by importing mx.charts.LineChart, my code completion found the classes but when compiling the same error occurs.
View 2 RepliesI'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:
<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 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 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.
