密度散点图(Density Scatter Plot),也称为密度点图或核密度估计散点图,是一种数据可视化技术,主要用于展示大量数据点在二维平面上的分布情况。与传统散点图相比,它使用颜色或阴影来表示数据点的密度,从而更直观地展示数据的分布情况。密度散点图能更好地揭示数据的集中趋势和分布模式,尤其是在数据量非常大时,避免了散点图中点
首先要把你想要绘图的数据调整成R语言可以识别的格式,建议大家在excel中保存成csv格式。作图数据格式如下:(今天偷懒啦,直接借用了iris数据集) Step2. 绘图数据的读取 data <- read.csv(“your file path”, header = T, check.names = F) #注释:header = T表示数据中的第一行是列名,如果没有列名就用head...

what histograms are to random variables; a scatterplot provides an indication of the shape and scales of the joint probability-density function of a given random vector, just as a histogram provides an indication of the shape and scale of the probability-density function of a given random variab...
