Creating a custom data tip function on a Flex PieChart control

by Peter deHaan on November 4, 2007

in Charting,PieChart,PieSeries

The following example shows how you can create a custom data tip function on a PieChart control in Flex by specifying the dataTipFunction property in your PieChart control. This example also shows how you can make all the data tips visible at the same time in the pie chart by setting the showAllDataTips property to true.

If you set the showAllDataTips property to true in your PieChart control, the data tips would be visible regardless of whether the user’s cursor was over the pie chart or not, but in the following example we only set the showAllDataTips property to true when the user rolls their mouse over the pie chart, and set it back to false when the user rolls out of the pie chart. For more information, see “Displaying all data tips at once on a Flex PieChart control”.

Sorting date columns in a DataGrid

by Peter deHaan on August 12, 2007

in DataGrid,ObjectUtil

Here’s an example of sorting a column of dates in a Flex DataGrid. The dates start out as Strings (such as “04/14/1980″) so you create a custom sortCompareFunction on that DataGrid column which converts the strings to dates so Flex will sort the dates in sequential order (as oppsed to string order). Hope that helps somebody out there.

I also created a little tooltip on the date column which shows the dates in a somewhat more readable form (“April 14 1980″) using the DataGridColumn object’s showDataTips and dataTipFunction properties.
