axis-labels

问题 By using ggplot and faced_grid functions I'm trying to make a heatmap. I have a categorical y axis, and I want y axis labels to be left aligned. When I use theme(axis.text.y.left = element_text(hjust = 0)) , each panels' labels are aligned independently. Here is the code: #data set.seed(1) gruplar <- NA for(i in 1:20) gruplar[i] <- paste(LETTERS[sample(c(1:20),sample(c(1:20),1),replace = T) ], sep="",collapse = "") gruplar <- cbind(gruplar,anagruplar=rep(1:4,each=5)) tarih <- data.frame(yil=

问题 I am playing with Plotly tools using python and I have made a polar plot as seen below using some dummy data: I would like to alter the axis so that the data I have (goes from around 20 to 50) is mapped to the entire 360° of the plot. Is there a way of doing this using a readymade command or do I need to write a function where you set the limits then map those numbers to degrees before changing axis labels. I have been looking through stack exchange but I can only find ways of changing it to

问题 After running the code below, the axis tick markers all overlap with each other. At this time, each marker could still have good resolution when zooming popped up by plt.show() . However, the figure saved by plt.savefig('fig.png') would lost its resolution. Can this also be optimised? from matplotlib.ticker import FuncFormatter from matplotlib.pyplot import show import matplotlib.pyplot as plt import numpy as np a=np.random.random((1000,1000)) # create scaled formatters / for Y with Atom

问题 I have many charts being generated dynamically. For some charts, the dates are near each other, so, axis labels are getting repeated Example: Date format used: d3.time.format("%d-%b-%y") Is there an in-built way to avoid duplication of labels? Or is there a good generic procedure which can avoid such duplication? Note that my charts have zooming feature also and the incoming data is dynamic, so I can't put in hardcoded values of "ticks" or "tickValues". Generating ticks or tickValues

问题 I'm plotting a heatmap using R plotly : set.seed(1) df <- reshape2::melt(matrix(rnorm(100*20),100,20,dimnames = list(paste0("G",1:100),paste0("S",1:20)))) library(plotly) library(dplyr) plot_ly(z=c(df$value),x=df$Var2,y=df$Var1,colors=grDevices::colorRamp(c("darkblue","gray","darkred")),type="heatmap",colorbar=list(title="Scaled Value",len=0.4)) %>% layout(yaxis=list(title=NULL),xaxis=list(tickangle=90,tickvals=10,ticktext="X-Label")) As you can see, plotly is not showing all y-axis ticks. My

问题 This question already has answers here : Adding greek character to axis title (5 answers) Closed 2 years ago . I am making barplots for different metal concentration in various materials, and need the axis to say μg/g . I've searched for how to implement greek characters into different plots, but I don't seem able to actually do so. It looks like I should be able to use ( expression(paste) ) - can anyone help me? This is an extract of my current script: BP.Ag <- ggplot(data=dat, aes(x

问题 I was answering this question that I faced a strange problem; I want to make a bar plot with ggplot2 and have x axis labels as the last character of Group column. Use substring(Group, 3, 3) for this purpose: substring(df$Group, 3, 3) # [1] "1" "2" "3" "1" "2" "1" "2" "3" "4" But when I use it in ggplot like below, it prints 1 instead of 4 at the last tick; ggplot(data=df, aes(x=Group, y=Value)) + geom_bar(stat="identity") + scale_x_discrete(labels = substring(Group, 3, 3), expand=c(0.1,0.1))

问题 I am creating a scatter plot using ggplot2. The default gives me an x axis that has every value form 0 to 30. I'd prefer to have it go by 5s or something like that. I have been trying to use scale_x_continuous(), but I get this: Error: Discrete value supplied to continuous scale Here is the code that I am trying to work with: Daily.Average.plot <- ggplot(data = Daily.average, aes(factor(Day), Mass))+ geom_point(aes(color = factor(Temp))) + scale_x_continuous(breaks = seq(0,30,5)) Daily

问题 I have data e.g. (1,3600), (2,4400), ... (33,15000) Where in (1,3000) -> 1 is a number -> 3600 is seconds If put in chart, the axis would show the "second" as number. I have set a code to show axis label in 1 hour interval. // Create an NumberAxis NumberAxis xAxis = new NumberAxis(); xAxis.setTickUnit(new NumberTickUnit(3600)); // Assign it to the chart xyPlot.setDomainAxis(xAxis); So now the axis labels are: 0 ... 3600 ... 7200 ... 10.800 ... How to make the axis labels show in hours? (0 ...

问题 I've got a nice, pretty JFreeChart-generated Line chart, with one exception - the last value on my X axis is getting truncated, like so: | | |_________|________|__________|_________|_________| 100 Hz 1 kHz 10 kHz 100 kHz 1 MHz 10 MH (Note the z in MHz is cut off). I've looked into the solution here: JFreeChart tick label cut off but because I'm manually specifying the range in a LogAxis it appears from the JavaDoc that setting the margin has no effect.
