ScatterChartData constructor
- List<
ScatterSpot> ? scatterSpots, - FlTitlesData? titlesData,
- ScatterTouchData? scatterTouchData,
- List<
int> ? showingTooltipIndicators, - FlGridData? gridData,
- FlBorderData? borderData,
- double? minX,
- double? maxX,
- double? baselineX,
- double? minY,
- double? maxY,
- double? baselineY,
- FlClipData? clipData,
- Color? backgroundColor,
- ScatterLabelSettings? scatterLabelSettings,
ScatterChart draws some points in a square space,
points are defined by scatterSpots
,
It draws some titles on left, top, right, bottom sides per each axis number,
you can modify titlesData
to have your custom titles,
also you can define the axis title (one text per axis) for each side
using axisTitleData
, you can restrict the y axis using minY
and maxY
value,
and restrict x axis using minX
and maxX
.
It draws a color as a background behind everything you can set it using backgroundColor
,
then a grid over it, you can customize it using gridData
,
and it draws 4 borders around your chart, you can customize it using borderData
.
You can modify scatterTouchData
to customize touch behaviors and responses.
You can show some tooltipIndicators (a popup with an information)
on top of each ScatterChartData.scatterSpots
using showingTooltipIndicators
,
just put spot indices you want to show it on top of them.
clipData
forces the LineChart to draw lines inside the chart bounding box.
