Sample Description

How to use this sample?

Sample allows you to change parameters of technical indicators shown on the chart: SMA, Bollinger Bands, MACD and Full Stochastic Oscillator. Change params in input controls to the right of the chart and see how indicators are changed.

How it works

All the changes in charts can be made using object model as described in Updating Chart using Object Model.

This sample uses auxiliary getTechIndicatorById function to obtain a link to technical indicator object and applySettingsChanges method to commit the changes made.

Note, that each indicator has the complex structure and parameters are very different, you can learn more about technical indicators available in AnyChart Stock in Technical Indicators section.

AnyChartStock JavaScript API

This sample uses the following methods, properties and events from AnyChartStock JavaScript API:

Item Type Description
needConfig Property (Boolean) Defines whether the access to full chart configuration object model is required.
applySettingsChanges Method Commits changes made to settings element of the objectModel.
getTechIndicatorById Method Gets the link to technical indicator object by its id.
setXMLFile Method Sets chart XML configuration file path.
write Method Adds the chart to HTML DOM as a child of the specified container.
onChartDraw Event This event is dispatched when the AnyChart Stock is drawn.
