# clip
• clip: number | false | ChartArea

# maintainAspectRatio
• maintainAspectRatio: boolean
Maintain the original canvas aspect ratio (width / height) when resizing. For this option to work properly the chart must be in its own dedicated container.
Default
true
# Defined in
types/index.d.ts:1634 (opens new window)
# normalized
• normalized: boolean
Chart.js is fastest if you provide data with indices that are unique, sorted, and consistent across datasets and provide the normalized: true option to let Chart.js know that you have done so.

# parsing
• parsing: false | { [key: string]: string; }
How to parse the dataset. The parsing can be disabled by specifying parsing: false at chart options or dataset. If parsing is disabled, data must be sorted and in the formats the associated chart type and scales use internally.
