Answer : This is simple with numpy and pylab . You can set the colormap to be whatever you like, here I use spectral. from pylab import imshow, show, get_cmap from numpy import random Z = random.random((50,50)) # Test data imshow(Z, cmap=get_cmap("Spectral"), interpolation='nearest') show() Your target image looks to have a grayscale colormap with a higher pixel density than 100x100: import pylab as plt import numpy as np Z = np.random.random((500,500)) # Test data plt.imshow(Z, cmap='gray', interpolation='nearest') plt.show() If you want to create an image file (and display it elsewhere, with or without Matplotlib), you could use NumPy and Pillow as follows: import numpy, from PIL import Image imarray = numpy.random.rand(100,100,3) * 255 im = Image.fromarray(imarray.astype('uint8')).convert('RGBA') im.save('result_image.png') The idea here is to create a numeric array, convert it to a RGB image, and sa

Answer : You can add a new method to your service like addData in which you can combine your previous data with new data like. import {Injectable} from '@angular/core'; import {BehaviorSubject} from 'rxjs/BehaviorSubject'; @Injectable() export class UserService { userDataSource: BehaviorSubject<Array<any>> = new BehaviorSubject([]); userData = this.userDataSource.asObservable(); updateUserData(data) { this.userDataSource.next(data); } addData(dataObj) { const currentValue = this.userDataSource.value; const updatedValue = [...currentValue, dataObj]; this.userDataSource.next(updatedValue); } } For someone that may come accross this issue with a BehaviorSubject<YourObject[]> . I found in this article a way to properly add the new array of YourObject import { Observable, BehaviorSubject } from 'rxjs'; import { YourObject} from './location'; import { Injectable } from &#

Example 1: css transition opacity /* Answer to: "css transition opacity" */ /* CSS transitions allows you to change property values smoothly, over a given duration. */ .myClass { vertical-align : top ; transition : opacity 0.3 s ; /* Transition should take 0.3s */ -webkit-transition : opacity 0.3 s ; /* Transition should take 0.3s */ opacity : 1 ; /* Set opacity to 1 */ } .myClass :hover { opacity : 0.5 ; /* On hover, set opacity to 2 */ } /* From `opacity: 1;` to `opacity: 0.5;`, the transition time should take 0.3 seconds as soon as the client starts to hover over the element. */ Example 2: opacity transition in css /* Opacity transition in CSS By using this we can add element transition with some delay. And due to transition delay its look like animation of element. */ div { transition : opacity 0.5 s ; /* Transition should take 0.3s */ -webkit-transition : opacity 0.5 s ; /* Transition should take 0.3s */ opacity : 1 ; /* Set

Example 1: on button click scroll to div angular / ? css or scss / html { scroll - behavior : smooth ; } / ? typescript / //use ViewportScroller in angular //in constructor private _vps : ViewportScroller //function scrollFn ( anchor : string ) : void { this . _vps . scrollToAnchor ( anchor ) } / ? HTML / < button ( click ) = "scrollFn('about')" > Scroll to div < / button > ///About section < div id = "about" > Lorem ipsum dolor sit amet consectetur adipisicing elit . Optio , quasi nostrum labore sequi neque sed nihil consequuntur ? Ea , dolorum minima , cumque explicabo dicta est sit harum dolores , assumenda ex non . < / div > Example 2: scrollto angular //there are a few options you can go with, the basic one being css only //css or scss html { scroll - behavior : smooth ; } //You could also user ViewportScroller - available in angular //..... private _vps : ViewportScroller

Example: std distance c++ // C++ program to demonstrate std::distance() # include <iostream> # include <vector> # include <iterator> using namespace std ; int main ( ) { vector < int > v ; int i ; for ( i = 0 ; i < 10 ; ++ i ) { v . push_back ( i ) ; } /*v contains 0 1 2 3 4 5 6 7 8 9*/ vector < int > :: iterator first ; vector < int > :: iterator last ; // first pointing to 0 first = v . begin ( ) ; // last pointing to 5 last = v . begin ( ) + 5 ; // Calculating no. of elements between first and last int num = std :: distance ( first , last ) ; // Displaying num cout << num << "\n" ; return 0 ; }

Example 1: get all indices of a value in list python indices = [ i for i , x in enumerate ( my_list ) if x == "whatever" ] Example 2: get all occurrence indices in list python a_list = [ 1 , 2 , 3 , 1 ] indices = [ ] for i in range ( len ( a_list ) ) : if a_list [ i ] == 1 : indices . append ( i ) # more concise way a_list = [ 1 , 2 , 3 , 1 ] indices = [ index for index , element in enumerate ( a_list ) if element == 1 ] Example 3: find an index of an item in a list python # Example List list = [ 'apples' , 'bannas' , 'grapes' ] # Use Known Entites In The List To Find The Index Of An Unknown Object Index_Number_For_Bannas = list . index ( 'apples' ) # Print The Object print ( list [ Index_Number_For_Bannas ] ) Example 4: get index of item in list list . index ( element , start , end ) Example 5: python search list of lists for value return index [ ( i , colour . index ( c ) )

Answer : The answer is : 1. add a div around the canvas for example : <div class="wrapper"> <canvas width="600" height="250"></canvas> </div> 2. add height to the div class in the css .wrapper { height: 500px !important; } (adjust height as you wish the responsive rendering) Bootstrap has an example page, which has a chart (using chartjs) that is responsive. So, I would point to that URL, which can be downloaded and we have a responsive chart. Dasbhoard Example showing Reponsive Chart I know this is an old post, but recently came across it. Please check https://www.chartjs.org/docs/latest/general/responsive.html#important-note It basically says that, Detecting when the canvas size changes can not be done directly from the canvas element. Chart.js uses its parent container to update the canvas render and display sizes. However, this method requires the container to be relatively positioned and dedicated

Example: delete conda from machine conda install anaconda - clean # install the package anaconda clean anaconda - clean -- yes # clean all anaconda related files and directories rm - rf ~ / anaconda3 # removes the entire anaconda directory rm - rf ~ / . anaconda_backup # anaconda clean creates a back_up of files / dirs , remove it # ( conda list ; cmd shouldn ' t respond after the clean up )

Example: container in bootstrap Containers Containers are the most basic layout element in Bootstrap and are required when using our default grid system. Choose from a responsive , fixed-width container ( meaning its max-width changes at each breakpoint ) or fluid-width ( meaning it’s 100 % wide all the time ) . While containers can be nested , most layouts do not require a nested container. Syntax : <div class= "container" > <!-- Content here --> </div>

Example 1: how to convert string to int js let string = "1" ; let num = parseInt ( string ) ; //num will equal 1 as a int Example 2: string to int javascript var text = '42px' ; var integer = parseInt ( text , 10 ) ; // returns 42 let myNumber = Number ( "5.25" ) ; //5.25 Example 3: javascript convert string to number or integer //It accepts two arguments. //The first argument is the string to convert. //The second argument is called the radix. This is the base number used in mathematical systems. For our use, it should always be 10. var text = '42px' ; var integer = parseInt ( text , 10 ) ; // returns 42 Example 4: string to number js let myNumber = Number ( "5.25" ) ; //5.25 Example 5: string to int js string to int js

Example: relative positioning html /*position: relative; An element with position: relative; is positioned relative to its normal position. Setting the top, right, bottom, and left properties of a relatively-positioned element will cause it to be adjusted away from its normal position. Other content will not be adjusted to fit into any gap left by the element.*/ div .relative { position : relative ; left : 30 px ; border : 3 px solid #73AD21 ; }
