figures

问题 I would like to monitor the basic quality of the figures produced in R on individual pages such as byte size of each page, ... I can now do only quality assurance of average pages, see the following chapter about it. I think there must be something builtin for the task than average measures. Code which produces 4 pages in Rplots.pdf where I would like to know the byte size of each page in an output here; any other statistics of the page outputs is also welcome; you can get the basic memory

问题 I have some problems with figures in Matlab. I divided my bar plot into two figures since I have totally 171 bars. I took the first half of the data at first (figure 1) and then the second half (figure 2). But then I got a problem with Xticks. Now both start from zero, but I would want the second half (figure 2) to be from 86 to 171 (or with intervals of 10 so that they are from 80 to 180, for instance). I tried set(gca, ‘XLim’, [86 171] to the second figure, but what happened was that bars

问题 I am using matplotlib version 1.4.3 and I wanted to make a Violinplot and I wanted to show the mean and the median, which is easy to do but I want to mark the mean and median so they can easily be distinguished between, by changing the colour and/or shape of one of them but I cannot see anything in the documentation that allows for that. Anyhelp would be greatly appreciated. violinplot(x, showmeans=True, showmedians=False, widths=1.0, showextrema=False) Example Violinplot with means and

问题 I made a GitHub wiki - a manual to a software package - and I want to transform it into a beautiful pdf manual. However, I have some trouble with figures - many of them are put in one of the following pages, much after the place in the text where it should be, what turns the document very difficult to read. To do so, I followed basically what was suggested here. Basically the idea is to: Clone the GitHub wiki; Convert the markdown files to a single pdf using pandoc: pandoc -s FirstSection.md

问题 I have been trying to draw arrows in Matlab in my figure but they all look terrible. Also, I want my arrowhead to be a solid triangle, not a V. I tried using the packages available on the Matlab File Exchange: arrow, arrows, arrows3, and probably at least one other one. I even tried manually creating an arrow in the Matlab figure editor, but when I adjust the line width, the arrow looks like this: I used the annotation command to create the arrow above: annotation(gcf,'arrow',[0.621875 0

问题 I am generating graphs for a publication and I'd like to be able to label the panels of a figure in ggplot itself (as opposed to exporting to publisher, etc) so that they just fit neatly together in the final document. I was going to try to do this by adding a letter ("A") into the title, but I'd like my titles centered and I'd like the letter in the upper lefthand corner. # base graph: ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species, shape = Species))+ geom_jitter(size =

问题 I am collecting data and plotting that data in real time. The data are produced by a motion capture system. I have one class DynamicDataset that is just a wrapper around a 2-column matrix (although it's more nuanced than that) with an event notifier for new data added; another class DynamicPlotter that listens for the data-added event and updates the plot dynamically. Appropriate code snippets: classdef DynamicDataset < handle properties newestData = []; data = [] end events DataAdded end

问题 I have a contour plot and I am using the current rendering: set(gcf, 'renderer', 'zbuffer'); but it is giving me this thick red line in the plot and I don't know how to get rid of it. I tried switching to: set(gcf, 'renderer', 'opengl'); but the quality is poor and I really need to have high quality images. Any suggestions? 回答1: In general, I let MATLAB choose which renderer is most appropriate, which means leaving the RendererMode property of the figure set to its default value of auto . A

问题 How to pad white-space on a matlab legend to the right of the text? I am using a combination of psfrag (and adobe illustrator for a few other diagram modifications), and will replace the placeholder text in a figure with an equation. The problem is that it tightly bounds the box on the placeholder text, while I want to leave room for my equation Start with the simple figure; h_plot = plot([0 1], [0 1]); h_legend = legend('A',0); The spacing I really want would be something like this with h
