How it works

AnyChart Stock Component allows real-time data loading. This sample shows how to load CSV data from the server using AJAX and add this data directly into the data set.

Initial XML configuration file (config.xml) contains only one data set with source_mode set to "InternalData", but with empty <csv_data> node. Such empty data set generates empty chart, which is overlaid with special <div>.

When user changes the data set, CSV file is loaded using AJAX, old data is removed using removeDataRange() method, and new data is pasted using appendData method. You can learn more about this technique in Real-Time Data Streaming and Data Manipulations article.

Note, that when data is changed we also change series name using object model, learn more about object model in Updating Chart using Object Model article. Don't forget, that working with object model is possible only when needConfig property is set to true.

Loading data with AJAX takes some time, so we place an overlay <div> with "Loading" message when loading starts, when loading ends - we hide it, note, that wMode should be set to "opaque" to allow showing anything over the Flash object.
