问题 I want to plot something like this in R. I found some similar solution here so I tried something similar: test <- data.frame(person=c("group 1", "group 2", "group 3"), value1=c(100,150,120), # male value2=c(25,30,45) , # female value3=c(25,30,45), # male value4=c(100,120,150), # female value5=c(10,12,15), # male value6=c(50,40,70)) # female library(reshape2) # for melt melted <- melt(test, "person") melted$cat <- '' melted[melted$variable == 'value1' | melted$variable == 'value2',]$cat <-

问题 I want to use both animated zoom and range selector in the vertical barchart plotted using Dygraph. Setting both animateZoom and rangeSelector options to true is not working . But any one of these two are working fine individually.Please suggest me the solution. Any help would be greatly appreciated. 回答1: Those two options don't work very well together, so the combination is disabled. When you have a range selection, you typically zoom the chart by dragging the handles on either end of the

问题 I have data frame (df) with 3 columns e.g. NUMERIC1: NUMERIC2: GROUP(CHARACTER): 100 1 A 200 2 B 300 3 C 400 4 A I want to group NUMERIC1 by GROUP(CHARACTER), and then calculate mean for each group. Something like that: mean(NUMERIC1): GROUP(CHARACTER): 250 A 200 B 300 C Finally I'd like to draw bar chart using ggplot2 having GROUP(CHARACTER) on x axis a =nd mean(NUMERIC) on y axis. It should look like: I used mean <- tapply(df$NUMERIC1, df$GROUP(CHARACTER), FUN=mean) but I'm not sure if it's

问题 I would like to add functional information to a HeatMap (geom_tile). I've got the following simplified DataFrame and R code producing a HeatMap and a separate stacked BarPlot (in the right order, corresponding to the HeatMap). Question: How can I add the BarPlot to the right edge/side of the Heatmap?? It shouldn't overlap with any of the tiles, and the tiles of the BarPlot should align with the tiles of the HeatMap. Data: AccessionNumber <- c('A4PU48','A9YWS0','B7FKR5','G4W9I5','B7FGU7',

问题 I'm working on a JavaFX program that can display different grocery items as a BarChart. My code structure uses an initial loading class, GroceryGrapher.java , a controller, GroceryGrapherController.java , and an .fxml file, GroceryGrapher.fxml . I'm relatively new to JavaFX and I've tried different approaches to creating and displaying my BarChart . For the most part I've resolved issues and can load the chart with its data and components, but my issue is that the chart won't display / update

问题 I have two problem, which can be illustrated by these screenshots: So, how to avoid text's truncation in these case ? Of course, the width is enough.Moreover, truncation differs for differen strings. 回答1: I suspect a layout or preferred size problem. You can override getPreferredSize() in ChartPanel to get a nice initial display, as shown here, and specify a layout like BorderLayout.CENTER or GridLayout to let the panel adopt the size of the enclosing Container . Failing this, please edit

问题 I'm New to r. Im trying to make a stacked bar plot. I could make it work using the barplot function. However I could not work out how to make the legend look nice. Now i'm trying to use ggplot2 but I really cant make the chart look correctly. The data represents a simulation comparing a bootstrap confidence interval against a standard parametric confidence interval based on the t-distribution. The data is already summarized. This is how my data.frame look like: test cr type2 1 Bootstrap 0.406

问题 Here is my code to generate 10 bars of different colors. I want to add legend respectively but it only shows yellow legend i can change its color but i want 3 legend. I think it shows only 1 color because there is only 1 series. Is it possible to add more than 1 legend for a single series? output: or if i can add this image as legend to the middle left of my chart i need how to display image in bar chart or how to create 3 different labels for a single series bar chart import javafx

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I have a list like this: gender = ['male','female','male','female'] What would be the simplest way to plot the count of this list as a bar plot using matplotlib? 回答1: Using collections.Counter() you can easily count the frequency of elements in your list. Then you can create a bar
