I have been looking for a simple way to chart some data dynamically but to no avail. I have been using LineChart from Astra but I cannot change its data dynamically.
I think this very crude example should work, but it doesn't:
Code:
// The flash simply consists of a LineChart called "chart" ...
import com.yahoo.astra.fl.charts.*;
import com.yahoo.astra.fl.charts.series.LineSeries;
[Code]....
I want to display the same data in a chart and a data grid. I want to use the same data provider for both of them to reduce the amount of SQL queries.How do I transform the database structure into the chart structure and into the table structure using ActionScript?*
Database structure in JSON format:
[
{key:, year:, value:},
{key:, year:, value:}
]
Data provider structure required by a chart:
[
{series1:, series2:, year:},
{series1:, series2:, year:}
]
Data provider structure required by data grid:
[
{key:, year2000:, year2001:, ...},
{key:, year2000:, year2001:, ...}
]
Is it possible to develop chart in flash (eg. bar chart, pie chart)?

View 0 RepliesI am a scientist who knows molecular biology well but is a neophyte to Flex/ActionScript. I created a ColumnChart representing a probability histogram. I want to allow users to select a range of values on the X-axis via 2 sliders separate from the chart itself (one for the minimum value, one for the maximum.) By default the column bars are blue. But when the user selects a range, I would like to highlight that range in the chart a different color (eg. orange). How can this be done using ActionScript?

View 1 RepliesI am using FlashBuilder 4 and doing a simple application in flex. I am displaying a graph with 10 random values and based on the values I am trying to change the itemrenderer dynamically like CandlestickItemRenderer and BoxItemRenderer. Now my requirement was, if the values are > 10. I want to show my chart with CandlestickItemRenderer else i want to show the remaining spots as BoxItemRenderer. I am failing to do this. Either I am getting all the shapes as BoxItemRenderer or CandlestickItemRenderer. I am sending the code as a text file along with this.

I have a question for you....I'm not able di draw a pie chart dynamically. I have the Layer1 with a F3DPieChart, 4 input text and a button, I put 4 numer in the 4 inputtext (sum total = 100) and when I press the button I would like to see pie Chart to appear with 4 slices that rappresented my 4 numbers.unfortunately it doesn't happen. This is the code on layer1:

I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void
{
var printSelection:Box = new Box();
[Code]....
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
i.e.
printSelection.includeInLayout = false;
addChild(printSelection);
I have the follow class :
package my.controls.charts.series
{
import mx.charts.series.LineSeries;
import mx.collections.ArrayCollection;
[Code]....
The new series name appear on the chart, but the data doest, and the chart always remains blank.

I need to display price of item for every date in the month. The chart can be Bar chart or plot chart.
Question: Suppose there is no data available for 01/15/2010 then, Is there a way to display (01/15/2010) on x axis but no (bar or plot point) corresponding y axis point ?
i.e. there will be a empty space between 2 bars or plot points.
Currently i am using 0 , But 0 is a valid value.
Let me know if such a display is possible.

I am wondering how will I proceed with the following requirement. I need to create a line chart of business data of the last 8 quarters. It is easy, but the requirement is that, there should not be a connection between last year's Q4 and this years Q1. In effect, using the same array collection i need to split the line chart so that it looks like two different lines on the same chart. How to proceed with it.
View 1 RepliesI am having an issue with ColdFusion's CFChart tag. I have a couple graphs that do not display properly. For a horizontal bar chart, when attempting to display 50 or more chart data items, the graph's bar labels stop plotting, but keeps plotting the bars themselves once it gets to bar number 50. I noticed making the chart height larger makes the issue worse as well. If i go from 1000px pixels to 2000px, it stopped plotting labels even sooner. The query that populates the chart items do not return blank label names either. See the screen below, the labels should keep plotting after "7 to 1".
I am running on ColdFusion 8 Developer Edition. Is this a possible limitation for ColdFusion's native charting capabilities? Or should I consider checking out Flex Charting instead?
<cfset hideZeroData = "25">
<cfparam name="paramID" default="25">
<cfset ecfData = QueryNew("ecfName,cumValue")>

I have a Flex line chart where I allow the user to change the y axis ranges. When a data point falls outside the ranges, the chart drops the line segments on either side of the out of range point leaving a gap in the data line. I'm currently using the data function to clamp the values out of range to the y axis min/max, but this displays misleading data.

I'm trying to prevent a default chart item roll over highlight in a Spark column chart.If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent.
So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either.
How can I Create an animated Bar Chart or Line Chart type of component in flash programmatically, which should depends upon an incoming XML data, the chart should have the basic criteria like, Chart Label, Item Tooltips, background grids (without using any image). There also needs an ability to change the data which should reflect the chart as well.
