How it works

This sample uses chart object model to change chart setting as described in Updating Chart using Object Model article.

Most of visible chart entities, such as series, event markers, indicators and other, have enabled attribute, which defines whether this element is shown or not. You can change the value of this attribute using objectModel access and commit changes using applySettingsChanges method - this leads to show/hide effect.

In this sample we change enabled attribute of technical_indicator entity and we obtain link to it using getTechIndicatorById method, but please note, that some technical indicators should be shown in separate charts (Full Stochastic and MACD in this sample), so we need to show/hide the charts in which they are placed, as decribed in Show/Hide Charts sample.

Also, you can set enabled to false in initial JSON or XML configuration and change it in the run time, in this sample MACD Indicator is disabled in config.xml, but when enabled is set to true - it is instantly shown.
