Actionscript 3 :: Show A Threshold Line In Flex Chart?
Jul 26, 2011
I am stuck with a requirement to display a horizontal line on a ColumnChart to indicate a threshold level. I have the data to the Chart as an ArrayCollection.
Is it possible to get the location of a value that is shown on the y axis? I think I will be able to place a line or 1px high canvas on top of the Chart to achieve this. Or better, is there any built in functionality that i may have overlooked or is there some open library that can achieve something like this?

I need a small help on Flex Line Chart. I 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 values 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'm trying to make chart which is combination of bar and line chart using Flex Charting API . Here x axis would be common and y axis would be different. note that y axis got different range of value one is % and other is amount. Any one got idea how to make this chart. Here line chart would be staked on top of bar chart . The line chart and never over laid or drawn on top of bar chart.

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.

My group is working on a Flex/AS3 scientific web application that is data intensive. Luckily the only plots involved are line charts. However, each line chart may have multiple traces (up to 24), and each trace may contain up to 2000 points. The user will need to zoom in and out and interact with the data (e.g. data tips, etc.).
The response I'm getting from developers is that's a lot of data to render in a plot in Flash. For reasons beyond the scope of this post, we can't sample the data to reduce the size (this has already been done and nature of the data prevents further sampling).
Rendering speed is critical for this app. What kind of rendering speed should I expect the Flex 4 line chart component to provide for a given number of points (e.g. 1 second to render 1000 points?)
Are there products available that handle plotting large data sets better, which can be incorporated in Flex (I've seen FusionCharts and ZingCharts online but have no idea how they compare with Flex's components)? Of those, which are easy to develop with while still providing a lot of flexibility in look and feel?

Apparently, 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.

I'm trying to show some data that's integers but the BarChart is using fractional values on the axis which makes no sense in this scenario. Is there any way to force the chart to only use integer values on the axis? I don't know the range so it could be anything from 1 to 10000000, so I can't just explicitly set up everything.

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.

I am using the standard Flex 3 BubbleChart component and I would like to customize a couple of the grid lines separately from the rest.
I would like to highlight a gridline in the X-direction as well as in the Y-direction to show a quadrant.
Is there any way to customize the look and feel of a subset of gridlines within a Flex chart (i.e. bubble chart)?

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 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 two requirements: the line need to be dashed as of now the line starts from top right corner of the first column to the same corner of the second column. How can i shift the line to the left, so that it starts from center of first column to center of second column.

I have a problem zooming in on a line chart with a dateTimeAxis as horizontal axis. I want to zoom in and out, by setting the minimum and the maximum attribute of the dateTimeAxis with a slider.

I 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?

I'm new to Flex/AS3. I've attached an example line chart below. I want to know if this type of graph can be created using the standard line-series chart available in Flex (Flash Builder 4.6), or whether there's something drawn below that is non-standard and would therefore require some rather involved customization. The key features are:
-Different line styles and colors (dashed, dot-dash, solid, thick, thin, opacity)
-Placement of units (y-axis "seconds" and x-axis "Hz")
-x-axis zoom/pan control bar below graph (move knobs in and out to set x-axis min and max plotted values)
-Log x-axis scale, linear y-axis scale
-Data Tip (or, some call it tool tip, not shown below)
-SI units for x- and y-axis tick labels.
My guess is that everything should be pretty standard to accomplish using Adobe's built-in charting (with the possible exception of item 6, see below). Is that a good assumption?I'm particularly concerned about the x- and y-axis tick labels (item 6). For example, the x-axis tick marks as a number would be:1, 10, 100, 1000, 10000, 100000, 1000000, 10000000 but they need to be replaced with SI units, where k=1000, and M=1000000, so the corresponding marks would be (replacing the numbers above with the strings below)"1", "10", "100", "1k", "10k", "1M", "10M".The same goes for the y-axis, where p represents 1e-12, and n represents 1e-9.I can create an algorithm that accepts a number and outputs a string to do the SI unit conversion. But given that, is there a way to easily manage the tick mark labels to replace the default numbers with such strings?
