That error is because you are trying to assign a key to a list, and list only can be indexed by intenger list[0], list[1], so on. So, hinstogram must be a dict not a list Make sure when you call add_to_hist method, pass a dict. You can init a dict...

The reason they aren't the same is because you use imhist for im and hist for the blocks. Hist separates data into 10 different bins based on your data range, imhist separates data based on the image type. Since your arrays are doubles, the imhist bins are from 0 to...

I think you've got the right idea, more or less, and are simply being caught up on syntax. For example, we can use the divide-by-ten-multiply-by-ten trick to add a LagBin column, and then groupby-count on that: In [21]: Clean["LagBin"] = (Clean["TLag"]//10)*10 In [22]: Clean Out[22]: TLag LagBin 0 NaN NaN...

You can either fit the data that you get from a histogram using one of several ways: Use numpy.polufit for polynomial fits Use scipy.optimize.curve_fit for fitting arbitrary functions There is also kernel density approximation: scipy.stats.gaussian_kde which is a standard representation for most statsiticians. In seaborn, you can plot sns.kdeplot for...

You can plot exactly as much of the histogram as you want by choosing a subsection of the matrix, bins = 100 xmin = 40 xmax = 60 [f,x]=hist(randn(1000000,1),bins); bar(x(xmin:xmax),f(xmin:xmax)) Alternatively, you can plot over a specified range of x bin values, xvalues = -1:0.1:0.9; [f,x]=hist(randn(1000000,1),xvalues); bar(x,f,'b') but all the...

Although you use xtic labels from your data file, the xtics are placed at integer x-values, starting at 0. Now, you cannot directly set arbitrary x-values when plotting histograms. You must use newhistogram at ... to shift the second part of the histogram further to the right: split = 8...

Use fillstyle pattern to select between different fill patterns for each bar type, and lt -1 (or lc rgb 'black') to use black as line color: set terminal pngcairo set output "diskimage.png" set style data histograms plot 'Disk.txt' using 2:xtic(1) fs pattern 2 lt -1 title "Oct-09 data growth(gb)",\ ''...

Inspired by http://stackoverflow.com/a/30555229/635387 I came up with the following solution: import matplotlib.pyplot as plt import numpy as np d=[0.05, 0.1, 0.2, 1, 2, 3] def LogHistPlot(data, bins): totalWidth=0.8 colors=("b", "r", "g") for i, d in enumerate(data): heights = np.histogram(d, bins)[0] width=1/len(data)*totalWidth left=np.array(range(len(heights))) + i*width plt.bar(left, heights, width, color=colors[i], label=i) plt.xticks(range(len(bins)),...

You can do it like this: value <- rnorm(300,mean=100,sd=20) nf <- layout(mat = matrix(c(1,2),2,1, byrow=TRUE), height = c(1,3)) par(mar=c(4,4,1,1)) boxplot(value, horizontal=TRUE, outline=TRUE,ylim=c(0,160), frame=F, col = "green1") hist(value,breaks=40,xlab="Runs",ylab="Runs frequency", main = "Score") ...

python,matplotlib,plot,histogram

The picture shows a bar chart and not a histogram. I am pointing this out, not only because I am an obnoxious pedant, but also because I believe it could help you find the right tool :-) Indeed, for your purpose plt.bar is probably a better pick than plt.hist. Based...

You didn´t use quotes in your histogram list, but I am assuming that you wanted to plot a list of strings like ["a" "b" "c" ...], right? As far as I know, it is not possible to use categorical values (like strings) for a histogram in netlogo plots. This is...

java,elasticsearch,max,histogram,aggregation

I think I found a solution: $ curl -XGET 'http://localhost:9200/localhost.localdomain/SET_APPS/_search?pretty=true' -d' { "aggregations" : { "time_hist" : { "histogram" : { "field" : "time", "interval" : 10125000, "order" : { "_count" : "asc" }, "min_doc_count" : 0, "extended_bounds" : { "min" : 1429010378445, "max" : 1431602378445 } }, "aggregations" :...

if you only need to do this for a handful of points, you could do something like this. If intensites and radius are numpy arrays of your data: bin_width = 0.1 # Depending on how narrow you want your bins def get_avg(rad): average_intensity = intensities[(radius>=rad-bin_width/2.) & (radius<rad+bin_width/2.)].mean() return average_intensities #...

If you just get the data from the hist function you can plot it in other, more flexible, ways. Is this more like what you want? OT = [124 124 124 125 125 125 126 249 249 250 250 250 312 312 312 438] binVals = unique(OT); histVals = hist(OT,...

Here is the answer. ggplot(EF_Lat_Am, aes(x=V1, y = V4, fill=V3, width=.85)) + geom_bar(position="dodge", stat="identity") + labs(x = "", y = "EF (T/ha)") + theme(axis.text=element_text(size=16),axis.title=element_text(size=20), legend.title=element_text(size=20, face='bold'),legend.text=element_text(size=20), axis.line = element_line(colour = "black")) + scale_fill_grey("Period") + scale_y_continuous(limits=c(0,120)) + theme_classic(base_size = 20, base_family = "") ...

Question 1 What do $mids and $equidist mean: From the help file: mids: the n cell midpoints. equidist: logical, indicating if the distances between breaks are all the same. Q2: Yes, with h1=hist(c(1,1,2,3,4,5,5,1.5), breaks=0.5:5.5) 1.5 will fall into the 0.5-1.5 categorie. If you want it to fall into the 1.5-2.5...

One possibility would be to use a 'hollow histogram', as described here: # assign your original plot object to a variable p1 <- ggplot(data = dat, aes(x = values, linetype = category, fill = category)) + geom_histogram(colour = 'black', position = 'identity', alpha = 0.4, binwidth = 0.4) + scale_fill_grey()...

This is one way to solve this problem that leverages the hist() function for most of the heavy lifting, and has the advantage that the barplot of the cumulative sum of y matches the bins and dimensions of the histogram of x: set.seed(1) mydata <- data.frame(y = runif (100, min=...

Use the xticks function: plt.xticks( arange(5), ('Tom', 'Dick', 'Harry', 'Sally', 'Sue') ) Complete example (by the way, your code doesn't work for me, but instead of your error, I get TypeError: len() of unsized object, so I'm histogramming manually here): import matplotlib.pyplot as plt listofnames = ['Al', 'Ca', 'Re', 'Ma',...
