AtlasSparklineItem

The painted item behind AtlasSparkline, a small axis-less line chart drawn with QPainter.

Since 1.4.0

The C++ item behind AtlasSparkline: a small line chart with no axes or captions, for the trend of a figure in a card or a row. It is drawn with QPainter, so it renders on Qt Quick's software backend as well as on the GPU. Use AtlasSparkline instead, which gives it the theme's accent colour and an accessible role; the properties are the same.

AtlasSparklineItem is a Qt Quick Item; its inherited properties work as usual.

Example

AtlasSparklineItem {
    values: cpu.usageHistory
    minimum: 0
    maximum: 100
    color: "steelblue"
}

Properties

Name	Type	Default	Description
`color`	`color`	`#3daee9`	The line's colour.
`fill`	`bool`	`false`	Adds a soft area under the line.
`lineWidth`	`real`	`1.5`	The line's width.
`maximum`	`real`	`NaN`	The value at the top of the item. `NaN` or an infinite value scales to the samples. Samples above it are drawn at the top edge.
`minimum`	`real`	`NaN`	The value at the bottom of the item. `NaN` or an infinite value scales to the samples. Samples below it are drawn at the bottom edge.
`minimumRange`	`real`	`0`	The least span an automatic scale shows, so a nearly flat series is not blown up.
`values`	`list<real>`	`[]`	The samples, oldest first, spread over the full width. Any value that is not finite (`NaN` or infinity) is a gap: the line breaks there. A single sample between gaps, or alone, is drawn as a dot.
