取决于您想要的粒度。我的直方图体验来自于进行照片分析并从图像生成颜色和亮度直方图 - 所以我通常有更多的数据可以工作，我已经知道我的界限（上限和下限）。
1000分100个桶可能太多但20-50可能没问题。因此，请搜索min和max的数据，使用它为每个存储桶创建适当的边界，然后循环遍历相关存储桶上的计数器的数据。
类似的东西：
class MyHistogram
{
int[] _histogram;
public void MyHistogram(int bucketCount, double[] data)
{
double minValue = data[0];
double maxValue = data[0];
for(int i=0;i<data.Length;i++)
{
if (data[i] < minValue) minValue = data[i];
if (data[i] > maxValue) maxValue = data[i];
}
double bucketSize = (maxValue - minValue) / bucketCount;
_histogram = new int[bucketCount];
for (int i = 0; i < data.Length; i++)
{
int bucket = (int)((data[i] - minValue) / bucketSize);
_histogram[bucket]++;
}
}
public int[] Histogram { get { return _histogram } }
}
