Here is my question:I have a hybrid chart that uses bars and linesI want to add to the right vertical axis a horizontal line that represents a break even

I have a Flex Column Chart, which shows bars with each positive and negative values.I only want to have a horizontal line at 0 to distinguish between positive and negative values.I turned off all the axis.How could I achieve to get this line?
View 1 RepliesI 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. The date labels change as should, but the lines disappear as I set the minimum or the maximum. Here's a part of the code I have:

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 want to show the second line series underneath the first one, however with this code they are appearing sequentially. Not sure how to make sure they are overlayed! I followed some code I saw for combining charts.. not sure what to do.
<mx:LineChart showDataTips="true" x="10" y="77" id="GlucoseChart" width="1009" height="219">
<mx:horizontalAxis>
<mx:DateTimeAxis dataUnits="hours" parseFunction="parseDateString" displayLocalTime="true" />
</mx:horizontalAxis>
<mx:series>

I would like a single horizontal line to go across my 100% x 100% stage, but how do I do that? Im thinking its about knowing what resolution the viewer has, and the writing a script for the line, but how?
View 2 RepliesI'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.
View 1 RepliesFlex: - Is it possible to export Chart/Graph/component with dataGrid data into xls file without using server side?
(Web Application)
I have gone through number of article but could not find any hind to do. As per few article it is possible to export data of dataGrid into xls by using as3xls-1.0.swc but not Chart.
I am looking to export data from dataGrid as well as Chart.
I have a dynamically created chart and I need to add a horizontal and vertical axis in a script. I can't put the chart into MXML because I'm dynamically changing the chart type, deleting and creating a new chart. Therefore, the variable that I use to create the chart, an instance of chartBase, doesn't have either a horizontalAxis or verticalAxis. How do I assign to them if they don't exist? Should I be using a different type? The graphs I want to use are line, bar, and HLOC and/or candlestick.
View 1 RepliesI need to replace multiple contiguous new line/line feed characters in flex with a single new line character.
Example:
The string
"My name is blah blah
My name is blah
"
Should be converted to
"My name is blah blah
My name is blah
"
Hope the example makes it easier to understand.
I am using a component to render it.
I guess using regex would be the easiest way to do this, but still it would be great if people can point me out to references/examples to get this done with ease.
I am using flex 4.5.
I wish to remove the thin origin line from the background of a Flex graph. I have converted one of axes to a Category axis and an origin line remains, that is now unwanted. The following seems to remove all the vertical lines as well as the origin
<mx:backgroundElements>
<mx:GridLines verticalShowOrigin="false"/>
</mx:backgroundElements>
While
<mx:backgroundElements>
</mx:backgroundElements>
Removes all background lines1
I have created a flex chart with multiple Y axis. I want that it shows origin for one of the data series. It shows the line, but on the wrong plase.
Maybe it is because I didn't tell to GridLines which axis use as a source? But, I am not sure if it is possible to do...
how to show horizontal origin on a chart with multiple axis.

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.
View 1 RepliesDoes anyone know of a good charting/graphing tool that supports dynamic pie charts, i.e.where a user could change the values by dragging, etc? It would need an event API so I could get access to the changed values.
View 2 RepliesMy 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?
I want to do a line chart example in flash cs3 or in flex.

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 have a Line Series Chart in Flex with values from 0 to 90. I would like to set the background of the chart in such a way that, 0 - 30 is in green, 31 - 60 is in red and 61 - 90 is in blue.
View 2 RepliesI 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 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.
View 1 RepliesI 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 want to draw stock price in real time as a candle graph. I get open flash chart from someone and it looks good at drawing. I don't know how to update the candle graph in real time (using Ajax?), and is it a good way? I use Python a lot. But I cannot find tools as easily to use as OFC.
View 3 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.
