labels

I'm seeing a weird behaviour in my D3 application and after hours of trying to figure out what's happening I hope someone can point me at the thing I obviously do wrong. I have simplified the app down to be very simple and still exhibit the problem. As you'll see it's derived from all the great D3 examples out there. The simple scenario I have an issue with is: select a node (by clicking on it) and, upon hitting the delete key remove said node along with all related links and labels of both the node and the links. The code pasted below is nearly there since it decreases the number of Nodes and

I'm trying to add percentage labels to a donut chart but have been unsuccessful in plotting a clear representation of percentage values (rounded and not overlapping) ## my data library(ggplot2) col <- c("white", "black", "transparent", "grey", "blue", "yellow", "green", "red", "pink", "orange", "brown") freq <- c(101, 68, 34, 18, 14, 5, 5, 3, 2, 1, 1) ## create data frame colour.df <- data.frame(col, freq) colour.df ## calculate percentage colour.df$percentage = colour.df$freq / sum(colour.df$freq)* 100 colour.df = colour.df[rev(order(colour.df$percentage)), ] colour.df$ymax = cumsum(colour.df

Question adapted from this question and solution: Highlighting individual axis labels in bold using ggplot2 I would like to selectively justify the horizontal axes labels depending on meeting a criteria. So borrowing from the above question and answer I've set up an example: require(ggplot2) require(dplyr) set.seed(36) xx<-data.frame(YEAR=rep(c("X", "Y"), each=20), CLONE=rep(c("A", "B", "C", "D", "E"), each=4, 2), TREAT=rep(c("T1", "T2", "T3", "C"), 10), VALUE=sample(c(1:10), 40, replace=T)) # Simple plot with factors on y axis ggplot(xx, aes(x = VALUE, y=CLONE, fill=YEAR)) + geom_bar(stat=

Ok.. I'm new to ruby/rails. So to compensate for my weakness, my company had a guy come in to help me create the bones of our website. He put in formtastic :label_method, so we could change what fields are displayed in the DDLB. When I moved my project to a new box, I got this error. :label_method is no longer available What I'm wondering is.. what do I use in it's place? Xaca Xulu I think it might be: :member_label According to http://rubydoc.info/gems/formtastic/2.0.0/Formtastic/Helpers/InputHelper "(Symbol, Proc, Method) — Deprecated, renamed to :member_label" If that doesn't work could you

I am trying to make a polar 'sypder' plot but I am having some problems with the axis labels. The xaxis tick lables always seem to end up on a layer below the y axis grid (the letters are covered by the grid line, as shown in the figure below), I would like them on top. I tried setting the zorders but with no success. If I set the zorder of the plotted lines above 2 they do go on top (in terms of layer) of the axis and grid... but I still want the labels to be visible on top of the plot. If I set them below 2 the lines go below the grid. Setting the zorder of the grid or the ticks labels does

Suppose the following data frame, I want to factorized var, and label numbers to Greek letters, from 1 to alpha, 2 to beta, 3 to gamma. But the following code does not work. var<-c(1,1,2,2,3,3) df<-as.data.frame(var) df$var<-factor(df$var, levels=c(1,2,3), labels=c("1"=expression(alpha), "2"=expression(beta), "3"=expression(gamma))) Why the final data frame is not greek letters but just text expressions? Can anyone help me on this? Thanks a lot. Does your locale support these characters? Does '\u03b1' print an alpha character? If not, you'll need to change your encoding. E.g., Sys.setlocale(

I'm trying to draw labels which look informative, clear and tidy. I was following example and raised one more question about label and axis formatting. For example, I have sales data which includes Brand, Categories and Expenditure in EUR. When sum of EUR is big (millions or more) labels look really hard to read and not informative. As a result, x-axis is in Scientific notation and also looks really uncleanly. I've manage to format labels in custom way: it shows Eur in thousands. geom_text(aes(label= paste(round(EUR/1000,0),"€"), y=pos), colour="white") Is there an easier or automated way? As
