酒吧的高度太大

-3

我正在實施d3圖表，但我的圖表中的酒吧正在穿越y軸意味着他們正在走出我的畫布。看起來高度是問題所在。不知道原因。如果任何值大於500，那麼我的y軸的比例就會變爲500，那麼就會從我的畫布中消失。但規模是由d3制定的。所以我不能操縱scale.This是我的HTML酒吧的高度太大

你可以把你的jsfiddle例子？ – Adam

這是我的小提琴，但在這chrt沒有得到渲染..dont知道爲什麼 – sahil

既可以鏈接到jsfiddle/codepen/etc上的託管版本，也可以提供相關文件'123.js'和'avb.json' –

你的問題是你d3.max函數返回不正確的值。因此，而不是這樣的：

d3.max(myData, function(d) { 
    console.log(d.val001) 
    return d.val001; 
    })

這樣做：

d3.max(myData, function(d) { 
    console.log(d.val001) 
    return +d.val001; //this is the change 
    })

這是由於你的函數不是你的字符串轉換爲整數。

我已經在我的代碼在這裏更改yScale.domain（[0，d3.max（tempData，函數（d）{返回selectValue（+ d）;但現在我的圖表沒有得到顯示爲 – sahil

什麼是'selectValue'？ – thatOneGuy

你正在嘗試做什麼'return selectValue（+ d）;' – SiddP
