The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Highlighting a AdvancedDataGrid Row when corresponding point clicked on PlotChart

Asked by glg3 in Adobe Flex, ActionScript

Tags: Flex 3, Advanced DataGrid, ArrayCollection, PlotChart

I'm pulling my hair out on this one...
I've got a plot chart and an advanced datagrid both supplied by the same dataProvider - an arraycollection. My goal is to have the row in the adg highlight when a point is clicked in the plotchart and visaversa - the point hightlight when the row is clicked...

At this point I'm focusing on the plotchart click with the row highlight. I've tried a number of solutions - and have gotten some interesting results, but not what I want..

The code below ends up highlighting all rows, and interestingly, when I mouse over the rows - they are unhighlighted. Clicking on the plotchart points does nothing...
