Javascript 如何使用d3.js处理条形图中的值log 0？

我已经尝试使用d3.js+c3.js来可视化数据。在右y轴，我需要柱状图的对数刻度。我已经遵循了来自的提示，并且它们奏效了

但问题是，当数据集中有数据0时，它会使条形图不显示。我尝试通过修改处理缩放的函数来处理此问题，如下所示：

for(var i=1; i<data_test_original.length; i++){
    if (data_test_original[i] === 0){
        data_logscale_tweet[i] = 0;
    }
    else {
        data_logscale_tweet[i] = Math.log(data_test_original[i]) / Math.LN10; 
    }      
}

您可以从这个窗口查看图表

您可以在此图表中看到，对于数据值0，条形图中显示值1。我的问题是：对于数据值0，如何将条形图值设置为0而不是1？

对数刻度应仅用于正数。如果你有一个零或负数，对数刻度没有意义，零应该显示为负无穷大，负数根本不能显示。嗯，，，，thx…但是当我尝试使用matlab时，对数0可以处理，也许你知道使用d3.js处理这种情况的一个技巧：你可以将它设置为适当的非常负数，比如-1337，而不是0。它仍然是不正确的，但它看起来或多或少是应该的。thx@Amadan，，，我会尝试你的建议：我编辑了一点你的问题，使它更清楚。希望我没有把事情弄糟。请查收。
