I'm using a graph with a <mx:LineSeries> . When I hover over the line it shows the data points as little circular points. How can I get these points to display all of the time?

itemRenderer="mx.charts.renderers.CircleItemRenderer"
When constructing a LineSeries in ActionScript, then set the itemRenderer... .

What is the best way to store a large number of data points?
For example temperature values which are measured every minute over lots of locations?
SQL databases with one row per data points doesn't seem very efficient.

I have a series of data points (tuples) in a list with a format like:
points = [(1, 'a'), (2, 'b'), (2, 'a'), (3, 'd'), (4, 'c')]
The first item in each tuple is an integer and they are assured to be sorted. The second value in each tuple is an arbitrary...

Hi,
I've been puzzling over path rendering for the past couple of days without any real solution.
By path rendering I mean given a set of x,y data points (at varying distance) to draw a dashed line (or in my case a rotated quad) of fixed length at regular...

Admittedly, you'd ideally want to group data points by distance from point to point, and this groups into a graph.
