Description

The SetIndexVisibility method sets whether a buffer should be visible on the chart. This can be used to hide buffers that are used for calculations but should not be displayed to the user.

Example

// Make buffer 0 visible
this.api.SetIndexVisibility(0, true);

// Hide buffer 1 (used for calculations only)
this.api.SetIndexVisibility(1, false);

// Conditionally show buffer based on user option
const showSignalLine = true; // This could be a user option
this.api.SetIndexVisibility(2, showSignalLine);
