Actionscript :: Add Glow Effect Flex 3 Chart?
Aug 14, 2009
I created a custom component in Flex 3 that contains a column chart. I also added code that will allow the user to drill down on a column when there is underlying detail data. If there is no data, clicking on the column has no effect. I want to make the column under the mouse glow when the drill down functionality is possible as a visual signal to the user. How do I make the column glow when my IF statement results in true?

I've come across several AS3 movies using what looks like a special kind of blending glow or blur effect. As I'm relatively new to AS3 I haven't come up with a similar effect. The effect looks like the one used here: [URL]

How do I make it so when I click an object, that object has an effect placed on it, using ambiguous programming, so I don't have to program each item individually.

I've come across a special kind of glow/blur effect on certain AS3 movies. Since I'm relatively new to AS3 I'm not sure how to achieve this effect, but it seems to be some kind of glow or blur. An example of the effect can be found in this game: [URL] How could I achieve this effect?

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.

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.

I made a gradient glow within the FLASH IDE on one of my textfields. I was wondering if there is a way to change the glow in as3? Apparently you can not change the glow in the flash IDE. It has to be white/black gradient.

I need to highlight a button's border, so I have created a glow filter like this:
<s:GlowFilter id="GlowFilter1"
color="0xD9D919"
blurX="30" blurY="40"
alpha="1"
/>
The problem is that I don't know to remove the effect. The effect remains in the opction as it was highlighted. Thus, I'd like to set a duration, or something that removes the effect I create.

Reproduce problem:
run code
click checkbox
click on the first input box
enter: 100
The red glowing error box should have disappeared, but it will disappear when you focus on another component e.g. the second input box. If you refersh the screen, click the checkbox, and TAB onto the first input box, type 100, the error glow will disappear as I expected. This is what I want for click also.

It's a bit of decoration to go behind a logo. When the dMove var is commented out I get the appropriate line of squares fading in and out at random spots along the x = 78 axis, but when introduced nothing appears at all...

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?

Flex 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,

I 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 ..?

I 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.

I would like to be able to specify the placement of a legend for a linechart. Currently, it continues to appear to the right of the chart. I have tried playing with the width/height of the chart to no avail... Putting the legend before the linechart in the mxml causes it to appear to the left. I can't seem to get it appear at the bottom though. I can't seem to find any good examples for this. They don't seem to specify anything but the legend usually shows up below the chart, I can't seem to do it.

I'm using a lineseries chart, but it gets fairly slow to re-render when I add a new point when the total # of points is ~1200 points. Granted, this is running on a fairly slow PC (~600 MHz). Reading the Flex documentation on how to speed up rendering (turning off dropshadows, turning off filterData, etc...) doesnt seem to help. I bound my chart to an ArrayCollection (rather than the array I used before which I manually updated) and it doesnt seem to be any faster. Adobe's documentation seems to have me believe that the Chart looks only at what changed since the last time it was updated, but i'm only adding one point!
If their info is correct, why does it take significantly longer (5 seconds) to update one point when I have ~1200 points then when I only have 2 points (instantaneous)? FYI - When I add a new point to my ArrayCollection, I have to do a "AC.refresh()" to get the DataBinding to pick up the new data.
