Css :: Setting Different Chart DataTip Styles In Flex Components
Nov 1, 2011I have a following issue:My task is to style a datatip for two charts in Flex 4.5.Both charts reside in two different <Group> based components which are added to the <Application>
So after a thorough research here is what I tried to do.First applying a css descending selectors:
#container#chart1 chartClasses|DataTip{
backgroundColor:white;
backgroundAlpha:0.01;
[Code]....
Then I would like to be able to get access to the instance of the CustomDataTip class.But I can't .So currently the only thing I can do is to create a distinct custom datatip renderer class for each chart.That could be fine if you have only a couple of charts you want to style but what can we do if we have many of them?

Jan 29, 2010Is it possible to tell flex to display a chart with no visible axis? I want the contents of the chart to take up all the available space. I can set the visibility on the AxisRenderer to false which will hide the axis but that leaves an empty space where the axis would usually be. How can I remove this empty space?
<mx:horizontalAxis>

I've tried setting the height on the renderer but that has no effect, and there is no height style on the axis itself.

How do I get it so that I only show datatips for the line but not the column?

View 1 RepliesFlex :: Prevent A Default Chart Item Roll Over Highlight In A Spark Column Chart?
Mar 3, 2011I'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.

View 1 RepliesFlex - Options To Create Line Chart In Flex For Data-intensive Web App?
Jan 13, 2012My 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?
Actionscript 3 :: Flex - Possible To Have Flex DataTips On Canvas Rather Than Chart Objects
Jan 17, 2010Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.
I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,

Flex :: Adobe Flex - Doing Group By At Client End (DataGrid To Pie Chart)?
Dec 23, 2010I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)
Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12
and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?

1 Dimensional Chart In Flex?
Apr 15, 2011I want a bubble chart that just shows items along a straight line. So I'd like the horizontal axis to essentially not exist. I have it working right now with the yField assigned to a field that happens to always be '1' on my test dataset.. but this is not going to be the case in general, so I need some way to restrict the y-axis... preferably without needing to go back to my model and parse through all my data to add a dummy value '1' on each entry.
Unfortunately setting min/max values just cuts off anything above or below rather than restricting entries.
I set computedMin and Maximum (no idea what they are and the docs don't really explain) but it didn't seem to restrict the data in any way.
