如何画Flot堆栈折线图、堆栈柱形图和堆栈条形图

Answer 1

var data = [ [gd(2012, 1, 1), 208557], [gd(2012, 1, 2), 125068], [gd(2012, 1, 3), 931208], [gd(2012, 1, 4), 450040], [gd(2012, 1, 5), 761180], [gd(2012, 1, 6), 744526], [gd(2012, 1, 7), 707095], [gd(2012, 1, 8), 601316], [gd(2012, 1, 9), 187495], [gd(2012, 1, 10), 716189], [gd(2012, 1, 11), 587141], [gd(2012, 1, 12), 147266], [gd(2012, 1, 13), 574670], [gd(2012, 1, 14), 175881], [gd(2012, 1, 15), 272519], [gd(2012, 1, 16), 211131], [gd(2012, 1, 17), 637015], [gd(2012, 1, 18), 794050], [gd(2012, 1, 19), 399010], [gd(2012, 1, 20), 799942], [gd(2012, 1, 21), 595768], [gd(2012, 1, 22), 717126], [gd(2012, 1, 23), 414923], [gd(2012, 1, 24), 462479], [gd(2012, 1, 25), 674334], [gd(2012, 1, 26), 20312], [gd(2012, 1, 27), 675892], [gd(2012, 1, 28), 808655], [gd(2012, 1, 29), 194543], [gd(2012, 1, 30), 664716], [gd(2012, 1, 31), 980720] ]; function gd(year, month, day) { return new Date(year, month - 1, day).getTime(); } 堆栈图选项 当你要画堆栈图时需要设定series.stack为true,这样Flot就会以堆栈图呈现,另外我们做的是堆栈折线图,我们可以设定series.lines.fill为true,让图表用颜色填满区块,程序代码如下. var data = [ [569106, gd(2012, 1, 1)], [743944, gd(2012, 1, 2)], [120865, gd(2012, 1, 3)], [890208, gd(2012, 1, 4)], [259723, gd(2012, 1, 5)], [177150, gd(2012, 1, 6)], [32430, gd(2012, 1, 7)], [274054, gd(2012, 1, 8)], [63435, gd(2012, 1, 9)], [994514, gd(2012, 1, 10)], [885453, gd(2012, 1, 11)], [289791, gd(2012, 1, 12)], [411717, gd(2012, 1, 13)], [95324, gd(2012, 1, 14)], [646479, gd(2012, 1, 15)], [448868, gd(2012, 1, 16)], [669678, gd(2012, 1, 17)], [909944, gd(2012, 1, 18)], [675965, gd(2012, 1, 19)], [281272, gd(2012, 1, 20)], [629781, gd(2012, 1, 21)], [330138, gd(2012, 1, 22)], [802835, gd(2012, 1, 23)], [139079, gd(2012, 1, 24)], [187101, gd(2012, 1, 25)], [354332, gd(2012, 1, 26)], [361090, gd(2012, 1, 27)], [78171, gd(2012, 1, 28)], [452212, gd(2012, 1, 29)], [404369, gd(2012, 1, 30)], [63509, gd(2012, 1, 31)] ]; 接着设定bars.horizontal为true,若这里没设定就会显示成柱形图,然后再设定yaxis.mode为"time",表示y轴以时间格式显示,另外我们还设定了yaxis.min及yaxis.max,如此可限制y轴刻度显示的最大及最小值.完整的选项程序代码如下.
