设备像素比率(Device Pixel Ratio) - Chart.js中文文档 - 笔下光年

设备像素比率(Device Pixel Ratio)
By default the chart's canvas will use a 1:1 pixel ratio, unless the physical display has a higher pixel ratio (e.g. Retina displays). For applications where a chart will be converted to a bitmap, or printed to a higher DPI medium it can be desirable to render the chart at a higher resolution than the default. Setting `devicePixelRatio` to a value other than 1 will force the canvas size to be scaled by that amount, relative to the container size. There should be no visible difference on screen; the difference will only be visible when the image is zoomed or printed. ## Configuration Options Namespace: `options` | Name | Type | Default | Description | |------------------|--------|---------------|-------| | devicePixelRatio | number | window.devicePixelRatio | Override the window's default devicePixelRatio. |
