Description

StartStream is used to begin producing streaming plots. This is a series of plots that are displayed rapidly, resulting in a moving video-like sequence. StartStream outputs the initial HTTP headers for the stream, disables browser-side caching, and prepares for the plot stream.

Parameters

None

Notes

The three functions StartStream(), PrintImageFrame, and EndStream are used together to produce streaming plots. Scripts producing streaming plots must use a web server. The PHP CLI will not work, because streaming plots require HTTP headers.

For more on streaming plots, see Section 4.9, “Streaming Plots”.

Example

See PrintImageFrame for a partial example, and Section 4.9.3, “Streaming Plots - Example” for the complete example.

History

This function was added in PHPlot-5.8.0. Prior releases are not able to produce streaming plots.
