why don't you develop your own data model and utility classes for different
computation. I think Tablue can give you more ideas & understanding if you just
The Data Visualization library charts will display whatever data you feed them and it is open source if you really need to dive deep (you can find it by digging through the Flex repository). You should write support for all of the filtering and summary data computations into your data model class. What you're asking for is very common and easily accomplished.
Sorry my question was completely different. Let me rephrase it again. If I
select a graph data in linechart how can I change the graph background color?. I
didn't say that I have some problem displaying data on graph for your
understanding it is more related to chart background element.
do you have any idea of it?
So on selection of a chart item, change the color of the entire chart background region?
FLEX LineCharts are a pain in the rear, unless you understand advanced ActionScript and overriding Renderers.
I am currently developing on a complex FLEX LineChart and I dont wish this on my worst enemy.
I took a look at the NASDAQ AIR application and the chart they use is very similar to mine. Only difference is, I am one developer and they paid millions to build theirs
Any info which renderer should I use. because I tried different at Series and
SeriesItem level but no luck till now. I also realized that you can change line
background color of line easily but this question related to background of whole
No I don't want to change entire chart background color I only want to change
the portion of chart background.
Actually the chart is representing hydrocarbons details inside the different
depth of earth. I want to make different zone in color If I select multiple
Hope this would clarify further.
Believe it or not I went every part of this article earlier. it is only
discussing how to change alternate color of chart background.
I really appreciate your interest.
Maybe look at the source for this open-source project:
it's probably not changing background portions, but it using overlay which might be a substitute for your requirements?
