C :: Borders Around Histogram
Mar 6, 2015
I'm able to get the graph, but now getting the border on the other side of the graph to align it with the right side of my screen.The output looks like that right now because I'm currently playing around with my y axis (right under the for loop) trying to scale everything. I've tried everything many different ways to get this to work.getting the border on the other side of the graph.
Code:
#include<stdio.h>
#include<Windows.h>
int main(void) {
int MAX = 0; //initialize and declare variables
int allcounts [10] = {0}; //store an array of integers for
}
[code]...

How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.
I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.
Code:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {
if( !CFrameWndEx::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = 250; // just playing around with size
cs.cy = 250;
return TRUE;
}
How can I do that?

I have following code to create histogram, but it gave wrong output. In the program input_vector read 100 double numbers. I want to create a histogram with bin size=5. Output is [0;0;0;0;0].
Code:
vector<double>three_dimensional_shape_retreival_Hough_Transform:: histogram_creation(vector<double> input_vector) {
long int i;
long int j;
Mat histogram_input(input_vector);
cout<<"Histogram Input Matrix:"<<histogram_input<<endl;
int histSize =5;

have this program .. i tried to make it work to give me this result output:
Code:
input array {1,3,5,1,1,8,6,6,1,3,2,1,6,8,8}
[0]

I'm trying to code one of the problems but it really is hard to catch errors for a novice like me at first.
I have to Write a single C function for computing the histogram of a list of nonnegative integers into 4 bins.
The main() function first initializes a positive integer array called List of size N, takes 3 inputs from the user A, B, C (assume 0 < A < B < C), and declares a second integer array Bin[4].
The doBinning function should count the number of elements of List in the interval [0, A) and store it in Bin[0], count of [A, B) in Bin[1], count of elements in [B,C) in Bin[2], and the number of elements >= C in Bin[3]
Code:
#include <stdio.h>
#define N 10
#define M 4
int *doBinning (int source[], int dest[], int a, int b, int c);
int main (){
[Code] ....
Somehow I keep getting error from ptr = doBinning(List[], Bins[]. What am I doing wrong? Code might contain some errors.

Scaling the yaxis on my histogram for one of my class projects. I've gotten mostly everything but stuck on scaling. I'm pretty sure it's something simple to do, but I'm having trouble, and I've tried everything to my knowledge to get it scaled from 0.1 - 1, like this:
Here is my code:
#include<stdio.h> //include all preprocessor directives
#include<Windows.h>
int main(void) {
int MAX = 0; //initialize and declare variables
int allcounts [10] = {0}; //store an array of integers for
int yaxis, xaxis = 0;
[Code] ....
I'm close, but every time I try and change my y axis in the for loop from 1 going down to 0.1, it doesn't give me a right output.

I have a text file which consist of several values. These values represent distance from origin to any point in the triangle. How can I create histogram from these values? Is there any functions in OpenCV which can create histogram from these values?
Below my sample values are given:
..........................
3.4 1.2 6.9 0.2 5.1 2.9

Write a function that generates 1000 normally distributed (Gaussian Probability Distribution) random numbers. Range should be between -3 and +3. Numbers should be double floating point.
There's more to it than that, but I've got it from there.

I have an assignment on image processing and amongst other question one of them specifies:calculate the equalized histogram of a grayscale image and show statistical data of your choice between the input and output images.
I am having trouble equalizing the histogram. Either I am missing the whole picture or minor details that cause problems.
Code:
// original histogram
for (i=0; i<lines; i++)
for (j=0; j<columns; j++)
hist[image_in[i][j]]++;
//histogram max and min
int hmax=-1,hmin=257;
for(int i=0;i<256;i++) {
[Code]...
I am thinking that my equalization formula is wrong, i might have incorrectly translated the mathematical formula from wikipedia to C code but i cant figure out why.

I am doing Histogram using pthreads and after long struggle on it.. finally it says 'Segmentation Fault (Core Dumped)'. I knew that error means something somewhere I am accessing to a wrong memory location.
Here is my code..
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
void Usage(char prog_name[]);
void Gen_data(void *p);
void Gen_bins(void *p);
int Which_bin(void *p);
void Print_histo(void *p);
[Code] ...
How to fix 'Segmentation Fault (Core Dumped)'?

I'm writing a program to display a histogram of 1000 Gaussian distributed numbers. I've generated the numbers using rand and now need to transform them. I have found the following formula to use
f(x) = exp(-x^2 / (2*sigma^2)) / sqrt(2*pi*sigma)
And I am unsure how to implement this into a function.

I have to make program which can generate a lot of random numbers and than prepare histogram with each number. Histogram must look that:
0 ( 50):*****************************************
1 ( 59):********************************************** ***
2 ( 42):***********************************
3 ( 49):****************************************
4 ( 41):**********************************
5 ( 53):********************************************
6 ( 60):********************************************** ****
7 ( 47):***************************************
8 ( 54):*********************************************
9 ( 45):*************************************

I want to create a vertical histogram in my code. I already made it go vertical but not the way I want it.
Example:
I want it like this:
Range1 Range2 Range3 Range4
And asterisks under each one, depending on the user input. (My code is below and doing it on here doesn't make it come out correctly)
But what I've managed to do is this:
Range1
*
*
*
Range2
*
*
Range3
*
*
*
*
Range4
*
*
Which I don't want. I want everything else to stay pretty much the same since I can only use some features such as Arrays and really basic functions.
Here is my code: (Worked fine last time I used it and I am doing it on Visual Studio 2010 (at uni) and 2013 (on my laptop)).
#include <iostream> //Start of code
using namespace std;
int MarkValueInput; //Mark entered by user
//Counter variables for ranges in While Loop
int counterlow; //Counter for low range
int countermidlow; //Counter for mid-low range
int countermidhigh; //Counter for mid-high range
int counterhigh; //Counter for high range
[Code] .....

Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging.
See [URL] ....
I'm trying to do this exercise from K&R on my own (with my own code), but I'm receiving a signal (Illegal instruction (Core dumped)) when the input is too large.
#include <stdio.h>
#define MAXWORDLENGTH 10
int main(void) {
int c; /* Character read */
long length[MAXWORDLENGTH + 1];
int reading_word = 0;
int word_size = 0;
[Code] ....
Where the problem might be occurring. I tried debugging with GDB but found no useful information.
Program received signal SIGILL, Illegal instruction.
0x00007ffff7a3b76e in __libc_start_main (main=0x4005d4 <main>, argc=1,
ubp_av=0x7fffffffe2a9, init=<optimized out>, fini=<optimized out>,
rtld_fini=<optimized out>, stack_end=0x7fffffffe298) at libc-start.c:258
258libc-start.c: No such file or directory.
The program output is also wrong when tested with the code provided at the link given above.

I am supposed to make a histogram. I succeeded in generating the integers for the histogram. But what I want to do is instead of displaying numbers in the console, I want something like "*" displayed for every integer there is in an array. It should look something like this.
*
****
*****
********
**********
******
****
***
*
As far as I understand, in some way I need to identify the integer in the array and for every single one of them I need to insert the symbol. I don't know how to identify it.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1{
class Program {
static void Main(string[] args) {
diceHistogram();

Here is what i have so far:
#include<fstream>
#include<iostream>
#include<string>

I also need to do a loop that scan the count array and check if the element is bigger than the previous one.
