[flexcoders] Line chart: how to materialize data points with dots?

[flexindesign]

Is there any way to have dots marking data points on a line chart? 

Basically, I would like to avoid a blank chart when only one data
point exists and also would like to visually materialize data points
in a  chart with date axis, so a line joining two data points days
apart do not look like it is linking data point on days in between, I
find it misleading.
