统计、可视化两不误,多达19种可视化技能你一定要掌握~~
今日小编继续给大家推荐优质绘图工具,帮助小伙伴们更好的是实现不同领域中可视化作品的快速绘制。今天的主角为R-grafify包,其包含5大类共19种可视化图表,舒适和符合出版要求的配色更是为这个可视化包填色,下面就通过以下两个方面介绍下整个优质可视化工具。
R-grafify介绍 R-grafify样例介绍
R-grafify介绍
这一部分小编重点放在R-grafify可绘制的5大类可视化图表和颜色搭配上,内容如下:
5大类可视化图表
R-grafify包可绘制的19种图表主要可分为以下5个小类:
Two variables、 Three or four variables、 Numeric X-Y Plots、 Before-after Plots Data distributions
下面的样例介绍部分,小编将进行具体介绍~~
颜色搭配
R-grafify 包有其自己独有的颜色搭配设计,这里直接列出其所有的颜色条,如下图所示:
你可以像使用ggplot2种的scale_fill... 和scale_colour... 函数一样使用R-grafify包的颜色名称进行颜色选择和设置。
R-grafify样例介绍
这一部分小编将对上述列举过的5大类图表进行一一介绍(有的类样例较多,将介绍几个典型的图表类型),详细内容如下:
Two variables
这一小类所含图表类型较多,这里小编简单列举3个样例,如下:
plot_scatterbar_sd()
plot_scatterbar_sd(data = data_1w_death, #data table
xcol = Genotype, #X variable
ycol = Death)+ #Y variable
hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
labs(
title = "Example of grafify::plot_scatterbar_sd function",
subtitle = "processed charts with plot_scatterbar_sd()",
caption = "Visualization by DataCharm") +
theme(
plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
size = 20, margin = margin(t = 1, b = 12)),
plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
plot.caption = element_markdown(hjust = 1,face = 'bold',size = 12))
plot_scatterbox()
plot_scatterbox(data_1w_death, #data table
Genotype, #X variable
Death, #Y variable
symsize = 3, #larger symbols
jitter = 0.2)
plot_point_sd()
plot_point_sd(data_1w_death,
Genotype,
Death,
symsize = 6, #larger symbols
ewid = 0.2, #narrower error bars
ColPal = "bright", #"bright" palette
ColRev = F) +
「注意」:这里更改了颜色条:ColPal = "bright",且ColRev设置成False。
Three or four variables
这类图表包含plot_3d_scatterbar(), plot_3d_scatterbox(), plot_4d_scatterbar(), plot_4d_scatterbox() 函数,具体如下:
plot_3d_scatterbar()
plot_3d_scatterbar(data_2w_Festing, #data table
Strain, #X variable
GST, #Y variable
shapes = Treatment,
symsize = 3, #grouping factor for shapes
ColPal = "vibrant") + #"vibrant" palette
hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
labs(
title = "Example of grafify::plot_3d_scatterbar function",
subtitle = "processed charts with plot_3d_scatterbar()",
caption = "Visualization by DataCharm") +
theme(
plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
size = 20, margin = margin(t = 1, b = 12)),
plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
plot.caption = element_markdown(hjust = 1,face = 'bold',size = 12))
plot_3d_scatterbox()
plot_3d_scatterbox(data_2w_Tdeath,
Time,
PI,
Genotype,
b_alpha = 0.5, #reduced opacity
ColPal = "contrast", #"contrast" palette
ColRev = T)
plot_4d_scatterbar()
plot_4d_scatterbar(data_2w_Tdeath,
Time,
PI,
Genotype,
Experiment,
b_alpha = 0.7,
ColPal = "okabe_ito")+
scale_colour_manual(values = c("black", "grey20"))
plot_4d_scatterbox()
plot_4d_scatterbox(data_2w_Tdeath,
Time,
PI,
Genotype,
Experiment,
b_alpha = 0.7,
ColPal = "okabe_ito")+
scale_colour_manual(values = c("black", "grey20")) #manual colour scale
Numeric X-Y Plots
此类图表包含plot_xy_NumGroup(), plot_xy_CatGroup() 函数,具体如下:
plot_xy_NumGroup()
plot_xy_NumGroup(airquality,
Wind,
Temp,
Ozone,
symsize = 3)
plot_xy_CatGroup()
plot_xy_CatGroup(neuralgia,
Age,
Duration,
Pain,
symsize = 3,
ColPal = "muted", #palette
ColRev = T)
Before-after Plots
此类图表包含plot_befafter_colours() , plot_befafter_shapes() 函数,具体如下:
plot_befafter_colours()
plot_befafter_colours(data = data_t_pdiff,
xcol = Condition,
ycol = Mass,
groups = Subject,
symsize = 5,
ColPal = "light",
ColRev = T)
Data distributions
此类图表包含plot_qqline(), plot_density() 和plot_histogram() 函数,具体如下:
lot_qqline()
plot_qqline(data = data_t_pratio,
ycol = Cytokine,
xcol = Genotype)
