histogram

问题 Is there a code that can bring the blue bars in this histogram plot to the front? If I remove alpha I can't see the blue bars at all. I'm using Python3 and Seaborn for this plot Thank you in advance g = sns.FacetGrid(df, hue='credit.policy', palette='coolwarm', height =5, aspect=2) g = g.map(plt.hist, 'fico', alpha=0.8, bins=30).add_legend() 回答1: You can achieve what you want with following code, import matplotlib.pyplot as plt plt.hist(df[df.Private == 'No']['F.Undergrad'], alpha = 0.6,color

问题 I have an experiment where I measured the performance of some algorithms relative to three baselines. I'd therefore like to plot histograms for the algorithms, with horizontal lines of various styles drawn through the histogram bars to show the baselines. Below is an example which I produced by manually drawing horizontal lines on a graph produced by Gnuplot. The histograms "sentence" and "document" represent the algorithms I tested, and "mono", "random", and "MFS" are the baselines. Is there

问题 My function called DicePlot, simulates rolling 10 dice 5000 times. In the function, it calculates the sum of values of the 10 dice of each roll, which will be a 1 × 5000 vector, and plot relative frequency histogram with edges of bins being selected in the same manner where each bin in the histogram should represent a possible value of for the sum of the dice. The mean and standard deviation are computed of the 1 × 5000 sums of dice values and the probability density function of normal

问题 I have calculated 3 histograms for an rgb image using imhist function in Matlab, one for each channel. I want to plot these histograms on the same graph, where for instance, the histogram for the first (red) channel stretches on the x axis from 0 to 255, the histogram for the second channel stretches from 256 to 511, and finally the histogram for the third channel stretches from 512 to 767. How can I do this? 回答1: Assuming uint8 precision, each call to imhist will give you a 256 x 1 vector,

问题 I'm still having problems with [histogram] . I have a global variable (age-sick) that stores the age of the turtles when they got sick...and I want to plot the distribution: histogram age-sick However I do not want the absolute number of turtles who got sick per every age, rather the relative one . Is there a way to do so? 回答1: I have tried to overcome the problem in the following way:​​ let age-freq (list) let i 0 while [ i <= (max age-sick)] [ let a filter [? = i] age-sick repeat (length a

问题 This is what I have so far: https://gist.github.com/daluu/fc1cbcab68852ed3c5fa and http://bl.ocks.org/daluu/fc1cbcab68852ed3c5fa. I'm trying to replicate Excel functionality. The line fits the default histogram just fine as in the base/original http://bl.ocks.org/daluu/f58884c24ff893186416. And I'm able to sort the histogram in descending frequency, although in doing so, I switched x scales (from linear to ordinal). I can't seem to map the line to the sorted histogram correctly at this point.

问题 I'm doing all the K&R exercises and I have finally been able to print a horizontal histogram. It look awful too, but I'll let you judge it. I have not been able to print a histogram of the lengths of words in its input vertically. How can I modify my program to do this? Question: Write a program to print a histogram of the lengths if words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging. histogram.c #include <stdio.h> #define

问题 I am trying to apply histogram normalization to create a dense color histogram. Split the channels into R, G, B Normalize the individual histogram Merge I think that this is the normal step perhaps if I am wrong please let me know. Now, for a rainbow image as shown below I get I get max of 255 for all 3 channel and 0 as min. Using the formula for Pixel - Min / (Max - min) * 255 I will get the same image as the original one back. What is the critical step that I am missing. Please advise me

问题 I guess my question is simple (even if the title is not...) but I was not able to find any clear answer yet. I want to plot histograms of Reaction Times in a psychophysics task. I need to plot two of them on the same figure: one for correct responses, the other for incorrect responses. I don't want to plot the absolute counts, but rather the relative proportion corresponding to: For correct responses: count(correct==1) / sum(count(correct==1) + count(correct==0)) For incorrect responses:

问题 Is it possible to assign ranges to a matrix. If you consider the below zeros matrix as a 'grid' for plotting: R = zeros(5,8); R = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 So can you treat this matrix as a grid so each x-axis zero can considered as a range? for example R(5,1) is a range 0-0.1 seconds . R(5,2) is a range 0.1-0.2 seconds etc. Can the range idea also be applied to the columns? The purpose for this is so I can read cell array data I have
