我正在尝试使用lazy_high_charts在我的 Rails 应用程序中实现 Highcharts Column-Drilldown Chart。我想显示从我的数据库中提取并存储在四个数组（areas、areaScores、departments 和 deptScores）中的数据。我在将 highchart 网站上列出的示例 (JSFiddle)中的 JS 转换为 ruby 时遇到问题。我无法找到任何有关在 ruby 中创建柱状钻取图表的资源。任何有关如何将钻取图表集成到我的 ruby 应用程序中的帮助将不胜感激。
我已经包含了 Highcharts 演示页面上显示的示例 JavaScript 和我的控制器方法，该方法用数据填充四个数组并构建 highchart。
Highcharts Column-Drilldown 图表示例 (Javascript)
$(function () {
Highcharts.data({
csv: document.getElementById('tsv').innerHTML,
itemDelimiter: '\t',
parsed: function (columns) {
var brands = {},
brandsData = [],
versions = {},
drilldownSeries = [];
// Parse percentage strings
columns[1] = $.map(columns[1], function (value) {
if (value.indexOf('%') === value.length - 1) {
value = parseFloat(value);
}
return value;
});
$.each(columns[0], function (i, name) {
var brand,
version;
if (i > 0) {
// Remove special edition notes
name = name.split(' -')[0];
// Split into brand and version
version = name.match(/([0-9]+[\.0-9x]*)/);
if (version) {
version = version[0];
}
brand = name.replace(version, '');
// Create the main data
if (!brands[brand]) {
brands[brand] = columns[1][i];
} else {
brands[brand] += columns[1][i];
}
// Create the version data
if (version !== null) {
if (!versions[brand]) {
versions[brand] = [];
}
versions[brand].push(['v' + version, columns[1][i]]);
}
}
});
$.each(brands, function (name, y) {
brandsData.push({
name: name,
y: y,
drilldown: versions[name] ? name : null
});
});
$.each(versions, function (key, value) {
drilldownSeries.push({
name: key,
id: key,
data: value
});
});
// Create the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Browser market shares. November, 2013'
},
subtitle: {
text: 'Click the columns to view versions. Source: netmarketshare.com.'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
legend: {
enabled: false
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: true,
format: '{point.y:.1f}%'
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
},
series: [{
name: 'Brands',
colorByPoint: true,
data: brandsData
}],
drilldown: {
series: drilldownSeries
}
})
}
});
});
我的控制器：
def generateOrgBreakdownReport
# First, query the database for the data you need for the report
@jsonanswerBRKD = queryDatabaseForOrgProgressReport()
# Second, process and combine data as needed for the report
@areaBreakdown, @deptBreakdown, @employBreakdown = computeAreaAndDeptPrepareScore(@jsonanswerBRKD)
# Third, you'll need to put the processed data into a format
# Highcharts will understand for the data series it uses
# for the graph.
#THESE ARRAYS HOLD THE NAMES AND SCORES OF AREAS AND DEPARTMENTS
@deptScores, @departments, @areaScores, @areas = cycleThroughProcessedDataAndCreateHighChartsDataSetsBreakdown(@areaBreakdown, @deptBreakdown, @employBreakdown)
# Last, we put the newly made data sets for Highcharts to work its magic.
#DONT KNOW HOW TO IMPLEMENT DRILLDOWN FOR RUBY
@orgBreakdown = LazyHighCharts::HighChart.new('column') do |f|
f.chart( type: 'column' )
f.xAxis(
title: { text: "Areas" },
type: 'category'
)
f.yAxis(
title: { text: "Preparedness Score (%)"},
)
f.series(
name: "Department Score",
colorByPoint: true,
data: @deptScores
)
f.series(
name: "Area Score",
data: @areaScores
)
f.title(
text: "Organizational Breakdown"
)
f.options[:xAxis][:categories] = @areas
f.drilldown({:series=>{
name:"Dept. Score",
data: @deptScore
}
})
end
end
