Type parameters

• HorzScaleItem = Time

Methods

remove()

remove(): void

Removes the chart object including all DOM elements. This is an irreversible operation, you cannot do anything with the chart after removing it.

Returns

void

resize()

resize(width, height, forceRepaint?): void

Sets fixed size of the chart. By default chart takes up 100% of its container.
