在日期格式轴中绘制ggplot2中的次要刻度线（不是网格刻度线）

本文介绍了在日期格式轴中绘制ggplot2中的次要刻度线（不是网格刻度线）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 限时删除！！ 我试图以黑白方式为出版物完成一些图形，并且在轴上遇到了一些问题。 我需要绘图轴（不是网格）中的数据的子标签，我通过使用 annotation_logticks（base = 2，sides =trbl）基2，因为我的数据是不相关的日志。 但似乎不适用于日期格式类型（xts）的y轴。 到目前为止，我得到的图是我所需要的，就是删除背景网格（该部分应该很容易）并在y上添加刻度轴（这对我来说是困难的部分）。 是我用来做图的代码： ratio_plot_start_time =01:45 ratio_plot_end_time =02： （x =比率* 100，y =发病））+ geom_point（aes（y =发病））p p p< - p + annotation_logticks（base = 2，sides =trbl） 用于构建图的数据为： > onsetratios 比例发病误差 1 0.01092106 2012-05-17 01:49:03 19.05407 2 0.02092106 2012-05-17 01:49:35 14.89534 3 0.03092106 2012- 05-17 01:51:01 12.82914 4 0.04092106 2012-05-17 01:50:22 21.45099 5 0.05092106 2012-05-17 01:50:22 21.45099 6 0.06092106 2012 -05-17 01:51:13 20.09877 7 0.07092106 2012-05-17 01:51:13 20.09877 8 0.08092106 2012-05-17 01:51:13 20.09877 9 0.09092106 2012-05-17 01:51:13 20.09877 10 0.10092106 2012-05-17 01:52:34 15.53187 11 0.11092106 2012-05-17 01:53:53 14.79303 12 0.12092106 2012-05-17 01:53:53 14.79303 13 0.13092106 2012-05-17 01:53:32 17.12521 14 0.14092106 2012-05-17 01:53:32 17.12521 15 0.15092106 2012-05-17 01:53:32 17.12521 16 0.16092106 2012-05-17 01:53:32 17.12521 17 0.17092106 2012-05-17 01:46:30 36.96600 18 0.18092106 2012-05-17 01:46:30 36.96600 19 0.19092106 2012-05-17 01:46:30 36.96600 解决方案我不建议使用 annotation_logticks 。这是做这件事的预期方法。我删除了标题，因为我没有安装字体。 编辑： 我借用函数此处，它可以正常工作，通过手工拆分结构提供： onsetratios onsetratios $ onset ratio_plot_start_time =01:45 ratio_plot_end_time =02:10 channelNo = 1 start_date< - as.POSIXct（paste（date，ratio_plot_start_time，sep =）） end_date< - as.POSIXct（paste（date，ratio_plot_end_time，sep =））日期< - 2012-05-17p geom_errorbar（aes（ymin =发作误差，ymax =发作+误差），宽度= 0.0）+ xlab（表达式（峰值计数的百分比））+ ylab（表达式（UT Time（2012 May 17 ）））+主题（方面.ratio = 2 /（1 + sqrt（5）））+ theme_bw（base_size = 14）+ annotate（text，x = max（onsetratios $ ratio），y = as.POSIXct （paste（date，ratio_plot_end_time，sep =）），vjust = 4，hjust = 2，label = paste（F，channelNo，'））+ ylim（c（start_date，end_date） ） insert_minor< - function（major_labs，n_minor）{labs c（sapply（major_labs，function（x）c（x，rep（，4））） ） labs [1：（length（labs）-n_minor）]} date_br1 date_br5 p + scale_x_continuous（breaks = 0:20，labels = insert_minor（seq（0，20，by = 5） ，4））+ scale_y_datetime（breaks = date_br1，labels = insert_minor（format（date_br5，％H：％M），4））+ theme（panel.grid.minor = element_blank ），panel.grid.major = element_blank（）） I'm trying to get some graphics done for a publication in black and white, and I'm having some trouble with the axis.I need to plot the subticks for the data in the axis (not the grid), and I found a trick around it by using the annotation_logticks(base=2, sides="trbl") with base 2, since my data is not relevant in log.But that doesn't seem to work for the y axis, which is in date format type (xts).The graph I got so far is the one bellow, all I need is to remove the background grid (that part should be easy) and to add the ticks on the y axis (that's the difficult part for me).This is the code I used to do the graph:ratio_plot_start_time = "01:45"ratio_plot_end_time = "02:10"channelNo = 1p <- ggplot(onsetratios, aes(x=ratio*100, y=onset)) + geom_point(aes(y=onset))p <- p + ylim(as.POSIXct(paste(date, ratio_plot_start_time, sep=" ")), as.POSIXct(paste(date, ratio_plot_end_time, sep=" ")))p <- p + geom_errorbar(aes(ymin=onset-error, ymax=onset+error), width=0.0)p <- p + xlab(expression("percent of peak counts"))+ ylab(expression("UT Time (2012 May 17)")) + theme(aspect.ratio = 2/(1+sqrt(5)))p <- p + theme_bw(base_size = 14, base_family = "Helvetica") + annotate("text",x=max(onsetratios$ratio),y=as.POSIXct(paste(date, ratio_plot_end_time, sep=" ")),vjust=4,hjust=2,label=paste("F", channelNo, "'"))p <- p + annotation_logticks(base=2, sides="trbl")And the data used for building the graph is:> onsetratios ratio onset error1 0.01092106 2012-05-17 01:49:03 19.054072 0.02092106 2012-05-17 01:49:35 14.895343 0.03092106 2012-05-17 01:51:01 12.829144 0.04092106 2012-05-17 01:50:22 21.450995 0.05092106 2012-05-17 01:50:22 21.450996 0.06092106 2012-05-17 01:51:13 20.098777 0.07092106 2012-05-17 01:51:13 20.098778 0.08092106 2012-05-17 01:51:13 20.098779 0.09092106 2012-05-17 01:51:13 20.0987710 0.10092106 2012-05-17 01:52:34 15.5318711 0.11092106 2012-05-17 01:53:53 14.7930312 0.12092106 2012-05-17 01:53:53 14.7930313 0.13092106 2012-05-17 01:53:32 17.1252114 0.14092106 2012-05-17 01:53:32 17.1252115 0.15092106 2012-05-17 01:53:32 17.1252116 0.16092106 2012-05-17 01:53:32 17.1252117 0.17092106 2012-05-17 01:46:30 36.9660018 0.18092106 2012-05-17 01:46:30 36.9660019 0.19092106 2012-05-17 01:46:30 36.96600 解决方案 I do not advise to use annotation_logticks. Here's the intended way to do that. I removed the title since I do not have the font installed.Edit:I borrowed the function from here, and it works fine, provided by manual breaks construction:onsetratios <- read.table("clipboard", head=T)onsetratios$onset <- as.POSIXct(onsetratios$onset)ratio_plot_start_time = "01:45"ratio_plot_end_time = "02:10"channelNo = 1start_date <- as.POSIXct(paste(date, ratio_plot_start_time, sep=" "))end_date <- as.POSIXct(paste(date, ratio_plot_end_time, sep=" "))date <- "2012-05-17"p <- ggplot(onsetratios, aes(x=ratio*100, y=onset)) + geom_point(aes(y=onset)) + geom_errorbar(aes(ymin=onset-error, ymax=onset+error), width=0.0) + xlab(expression("percent of peak counts"))+ ylab(expression("UT Time (2012 May 17)")) + theme(aspect.ratio = 2/(1+sqrt(5))) + theme_bw(base_size = 14) + annotate("text",x=max(onsetratios$ratio),y=as.POSIXct(paste(date, ratio_plot_end_time, sep=" ")),vjust=4,hjust=2,label=paste("F", channelNo, "'")) + ylim(c(start_date, end_date))insert_minor <- function(major_labs, n_minor) {labs <- c( sapply( major_labs, function(x) c(x, rep("", 4) ) ) ) labs[1:(length(labs)-n_minor)]}date_br1 <- seq(from = start_date, to = end_date, by = "1 min")date_br5 <- seq(from = start_date, to = end_date, by = "5 min")p + scale_x_continuous(breaks = 0:20, labels = insert_minor(seq(0, 20, by=5), 4)) + scale_y_datetime(breaks = date_br1, labels = insert_minor(format(date_br5, "%H:%M"), 4)) + theme(panel.grid.minor=element_blank(), panel.grid.major=element_blank()) 这篇关于在日期格式轴中绘制ggplot2中的次要刻度线（不是网格刻度线）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 1403页，肝出来的..
