Realtime Charts
Description of the general approach of creating realtime charts in ChartDirector.

Simple Realtime Chart
This sample program demonstrates a realtime chart with configurable chart update rate, in which the chart image is being updated via streaming.

Realtime Chart with Snapshot
The example extends the Simple Realtime Chart example by adding buttons to download the chart in PNG and PDF formats.

Realtime Chart with Track Line
This sample program demonstrates a realtime chart with configurable chart update rate, in which the chart image is being updated via AJAX means. It includes a track cursor that updates the legend dynamically to display the data values as the mouse cursor moves over the chart. When the mouse is not over the chart, the track cursor will display the latest data values.
