如何自定义Google图表直方图

Question

我想自定义一个列直方图，像行中一样用虚线表示。

Answer 1

不认为这会改变风格
也不是这个图表

上可用的样式列的角色，但你可以尝试改变风格的手工

$.each($('rect[fill="#3366cc"]'), function (index, bar) { 
     $(bar).attr('stroke', '#ffffff'); 
     $(bar).attr('stroke-width', '3'); 
    }); 

任何配置选项

a MutationObserver用于防止图表恢复为其原始样式，
任何时候都有激活知音如悬停

看到下面的工作片段...

google.charts.load('current', { 
 
    callback: drawChart, 
 
    packages: ['corechart'] 
 
}); 
 

 
function drawChart() { 
 
    var data = google.visualization.arrayToDataTable([ 
 
    ['Dinosaur', 'Length'], 
 
    ['Acrocanthosaurus (top-spined lizard)', 12.2], 
 
    ['Albertosaurus (Alberta lizard)', 9.1], 
 
    ['Allosaurus (other lizard)', 12.2], 
 
    ['Apatosaurus (deceptive lizard)', 22.9], 
 
    ['Archaeopteryx (ancient wing)', 0.9], 
 
    ['Argentinosaurus (Argentina lizard)', 36.6], 
 
    ['Baryonyx (heavy claws)', 9.1], 
 
    ['Brachiosaurus (arm lizard)', 30.5], 
 
    ['Ceratosaurus (horned lizard)', 6.1], 
 
    ['Coelophysis (hollow form)', 2.7], 
 
    ['Compsognathus (elegant jaw)', 0.9], 
 
    ['Deinonychus (terrible claw)', 2.7], 
 
    ['Diplodocus (double beam)', 27.1], 
 
    ['Dromicelomimus (emu mimic)', 3.4], 
 
    ['Gallimimus (fowl mimic)', 5.5], 
 
    ['Mamenchisaurus (Mamenchi lizard)', 21.0], 
 
    ['Megalosaurus (big lizard)', 7.9], 
 
    ['Microvenator (small hunter)', 1.2], 
 
    ['Ornithomimus (bird mimic)', 4.6], 
 
    ['Oviraptor (egg robber)', 1.5], 
 
    ['Plateosaurus (flat lizard)', 7.9], 
 
    ['Sauronithoides (narrow-clawed lizard)', 2.0], 
 
    ['Seismosaurus (tremor lizard)', 45.7], 
 
    ['Spinosaurus (spiny lizard)', 12.2], 
 
    ['Supersaurus (super lizard)', 30.5], 
 
    ['Tyrannosaurus (tyrant lizard)', 15.2], 
 
    ['Ultrasaurus (ultra lizard)', 30.5], 
 
    ['Velociraptor (swift robber)', 1.8]]); 
 

 
    var options = { 
 
    title: 'Lengths of dinosaurs, in meters', 
 
    legend: { position: 'none' }, 
 
    height: 400, 
 
    colors: ['#29b6f6'] 
 
    }; 
 

 
    var container = document.getElementById('chart_div'); 
 
    var chart = new google.visualization.Histogram(container); 
 
    var observer = new MutationObserver(function() { 
 
    $.each($('rect[fill="#29b6f6"]'), function (index, bar) { 
 
     // change stroke 
 
     $(bar).attr('stroke', '#ffffff'); 
 
     $(bar).attr('stroke-width', '4'); 
 
     // round corners 
 
     $(bar).attr('rx', '6'); 
 
     $(bar).attr('ry', '6'); 
 
    }); 
 
    }); 
 
    observer.observe(container, { 
 
    childList: true, 
 
    subtree: true 
 
    }); 
 
    chart.draw(data, options); 
 
}
