Question

使用Dashin.io框架创建一些不错的图表。我正在尝试构建应用程序正在寻找的特定数组输出，并且我非常接近，但我认为我需要帮助创建数组的另一个维度。

这就是我所拥有的：

r = Redis.new(:host => "127.0.0.1", :password => 'password')
assGroups=['group1','group2', 'group3', 'group4']
points = ['Day', 'group1','group2', 'group3', 'group4']

history = 3
i = 0

while i <= history do
    getdate = (Date.today-i).strftime("%Y-%m-%d")
    i += 1
    countArr=[getdate]
    points.push(countArr)

    for group in assGroups
        query = [getdate,":",group].join()
        queue = r.hgetall query
        dCount = queue['incidents'].to_i
        countArr << dCount
    end
end
print points

这是给我的

["Day", "group1","group2", "group3", "group4", ["2016-06-06", 63, 13, 86, 13], ["2016-06-05", 64, 13, 84, 13], ["2016-06-04", 63, 13, 84, 13], ["2016-06-03", 64, 13, 84, 13]]

这非常接近，但我需要，＃34; Day＆＃34;并将它自己的数组分组，所以这将是我想要的输出：

[["Day", "group1","group2", "group3", "group4"], ["2016-06-06", 63, 13, 86, 13], ["2016-06-05", 64, 13, 84, 13], ["2016-06-04", 63, 13, 84, 13], ["2016-06-03", 64, 13, 84, 13]]

看起来最简单的更改是确保points在您第一次定义时是一个多维数组： points = [['Day', 'group1','group2', 'group3', 'group4']]
