flot chart tips
Flot 文档比较混乱
完整数据
[ series1, series2, ... ]
一个 series 的格式
{
color: color or number
data: rawdata
label: string
lines: specific lines options
bars: specific bars options
points: specific points options
xaxis: number
yaxis: number
clickable: boolean
hoverable: boolean
shadowSize: number
}
legend 参数
legend: {
show: boolean
labelFormatter: null or (fn: string, series object -> string)
labelBoxBorderColor: color
noColumns: number
position: "ne" or "nw" or "se" or "sw"
margin: number of pixels or [x margin, y margin]
backgroundColor: null or color
backgroundOpacity: number between 0 and 1
container: null or jQuery object/DOM element/jQuery expression
}
xy 坐标
xaxis, yaxis: {
show: null or true/false
position: "bottom" or "top" or "left" or "right"
mode: null or "time"
color: null or color spec
tickColor: null or color spec
font: null or font spec object
min: null or number
max: null or number
autoscaleMargin: null or number
transform: null or fn: number -> number
inverseTransform: null or fn: number -> number
ticks: null or number or ticks array or (fn: axis -> ticks array)
tickSize: number or array
minTickSize: number or array
tickFormatter: (fn: number, object -> string) or string
tickDecimals: null or number
labelWidth: null or number
labelHeight: null or number
reserveSpace: null or true
tickLength: null or number
alignTicksWithAxis: null or number
}
tickLength = 0 不显示背景格子
options 写法
在 $.flot(‘#div-id’,dataArr,options) 情况下:
var options = {
series: {
lines, points, bars: {
show: boolean
lineWidth: number
fill: boolean or number
fillColor: null or color/gradient
}
points: {
radius: number
symbol: "circle" or function
}
bars: {
barWidth: number
align: "left" or "center"
horizontal: boolean
}
lines: {
steps: boolean
}
shadowSize: number
},
colors: [ color1, color2, ... ]
}
grid
grid: {
show: boolean
aboveData: boolean
color: color
backgroundColor: color/gradient or null
labelMargin: number
axisMargin: number
markings: array of markings or (fn: axes -> array of markings)
borderWidth: number
borderColor: color or null
minBorderMargin: number or null
clickable: boolean
hoverable: boolean
autoHighlight: boolean
mouseActiveRadius: number
}
borderWidth = 0 去掉最外面的黑框
动态修改数据(重画 chart)
var flot_gs=$.flot('#flot_div',data1,option1);
flot_gs.setData(data2);
flot_gs.draw();
动态修改options
把 grid.borderWidth 0 改为 10
var flot_gs=$.flot('#flot_div',data1,option1);
flot_gs.getOptions().grid.borderWidth=10;
flot_gs.draw();
setupGrid()
没有参数。重新计算 坐标轴、ticks 和 legend 等。一般放在 flot_gs.draw() 前面。
查看 object 结构
console.log(flot_bar
options 内容
console.log(flot_bar.getOptions())
