1. Python 生成的图片没有办法像 MatLab 生成的 .fig 图片那样,可以由【属性检查器】进行二次编辑,或者由【openfig】函数将图中信息重新提取并二次处理; 2. Python 需要专门的【Pandas】来操作 dataframe,对于 heatmap 绘制来说不如 MatLab 直接处理矩阵高效。 本文横向比较了 Excel、Origin、MatLab 和 Python ...

只需要一个python数据框dataframe就可以快速添加各类注释 当数据框df被给定时,该dataframe中的所有列都被单独作为anno_simple注释。比如,下面一个数据框df中有4列:AB、CD、EF、F,所有4列都会被自动画成列注释图。如果某一列不是连续型,而是字符等分类型变量,也可以用anno_boxplot或者anno_scatterplot等添加箱线图...

Seaborn will use the column name of the DataFrame as the title on the x-axis and y-axis. This is very convenient, so the sample code can be very simple! Plotly Express Similar to Matplotlib.imshow(), Plotly Express’s imshow() is used to draw 2D regular raster. However, Plotly Express...
