The RemoveAllObjects method removes all chart objects of a specified type from the chart. This is useful for cleaning up multiple objects at once. The method can remove either regular objects or static objects, depending on the isStatic parameter.

Example

// Remove all trend lines
this.api.RemoveAllObjects(TObjectType.TREND_LINE);

// Remove all static text labels
this.api.RemoveAllObjects(TObjectType.TEXT, true);

// Clean up all drawing objects
const objectTypes = [
  TObjectType.TREND_LINE,
  TObjectType.RECTANGLE,
  TObjectType.TRIANGLE,
  TObjectType.TEXT,
];

for (const type of objectTypes) {
  this.api.RemoveAllObjects(type);
}

// Remove objects and log count
const beforeCount = this.api.GetObjectCount();
this.api.RemoveAllObjects(TObjectType.RECTANGLE);
const afterCount = this.api.GetObjectCount();
console.log(`Removed ${beforeCount - afterCount} rectangle objects`);
