figure

I use a bar graph to indicate the data of each group. Some of these bars differ significantly from each other. How can I indicate the significant difference in the bar plot? import numpy as np import matplotlib.pyplot as plt menMeans = (5, 15, 30, 40) menStd = (2, 3, 4, 5) ind = np.arange(4) # the x locations for the groups width=0.35 p1 = plt.bar(ind, menMeans, width=width, color='r', yerr=menStd) plt.xticks(ind+width/2., ('A', 'B', 'C', 'D') ) I am aiming for Hooked I've done a couple of things here that I suggest when working with complex plots. Pull out the custom formatting into a

Does anyone know how to number the figures in the captions, for HTML format R Markdown script? For PDF documents, the caption will say something like: Figure X: Some Caption Text However, the equivalent caption for the HTML version will simply say: Some Caption Text This makes cross-referencing figures by number completely useless. Here is a minimal example: --- title: "My Title" author: "Me" output: pdf_document: default html_document: default --- ```{r cars, fig.cap = "An amazing plot"} plot(cars) ``` ```{r cars2, fig.cap = "Another amazing plot"} plot(cars) ``` I have tried setting toc ,

I got a for i=1:15 . Inside I generate a variable d=1:0.01:10 , which is the x'x axis and based on this, I create a continuous function F(d) which has 2 unique variables pitch and yaw. I then plot this using different colors in every recursion using cmap = hsv(15); . So then it is: d=1:0.01:10; cmap = hsv(15); for i=1:15 pitch = unidrnd(10); yaw = unidrnd(10); for j=1:length(d) F(j) = d(j)*3*pitch*yaw; %// some long calculation here end p1 = plot(d,F,'Linewidth', 1.0); title ('blah blah') set(p1, 'Color', cmap(i,:)); hold on; legend (['pitch,yaw:', num2str(pitch) num2str(yaw)]) end hold off;

I have an externally created png image in a local directory that I'd like to import to a report using knitr. The ultimate target filetype is html. I have no trouble getting my own figures to appear when I create them with R code, but I'm at a loss what I would have thought was a simpler problem. While I'm at it, how would I import a figure for which I have a url? If you already have a local image, you can just use the HTML or markdown syntax to include it in your document. HTML syntax is <img src="path/to/your/image" /> and markdown is  . 来源： https://stackoverflow

How do I obtain all the axes handles in a figure handle? Given the figure handle hf , I found that get(hf, 'children') may return the handles of all axes. However, the Matlab Help suggests that it may return more than just the axes handles: Children of the figure . A vector containing the handles of all axes, user-interface objects displayed within the figure. You can change the order of the handles and thereby change the stacking of the objects on the display. Is there any way to obtain only the axes handle in the figure handle? Or how do I know if the handle returned by get(hf, 'children')

I want to plot data, then create a new figure and plot data2, and finally come back to the original plot and plot data3, kinda like this: import numpy as np import matplotlib as plt x = arange(5) y = np.exp(5) plt.figure() plt.plot(x, y) z = np.sin(x) plt.figure() plt.plot(x, z) w = np.cos(x) plt.figure("""first figure""") # Here's the part I need plt.plot(x, w) FYI How do I tell matplotlib that I am done with a plot? does something similar, but not quite! It doesn't let me get access to that original plot. If you find yourself doing things like this regularly it may be worth investigating the
