Heat Map热图

参考wiki

A heat map (or heatmap) is a graphical representation of data where the individual values contained in a matrix are represented as colors. “Heat map” is a newer term but shading matrices have existed for over a century

“热图(或热图)是数据的图形表示，其中矩阵中包含的各个值用颜色表示。“热图”是一个较新的术语，但是阴影矩阵已经存在了一个多世纪”

Heat maps originated in 2D displays of the values in a data matrix. Larger values were represented by small dark gray or black squares (pixels) and smaller values by lighter squares.

“热图起源于数据矩阵中数值的二维显示。较大的值由小的深灰色或黑色方块(像素)表示，较小的值由较亮的方块表示。”
