17 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser. 18 | 19 | The page will reload if you make edits.
20 | You will also see any lint errors in the console. 21 | 22 | ### `npm test` 23 | 24 | Launches the test runner in the interactive watch mode.
25 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information. 26 | 27 | ### `npm run build` 28 | 29 | Builds the app for production to the `build` folder.
30 | It correctly bundles React in production mode and optimizes the build for the best performance. 31 | 32 | The build is minified and the filenames include the hashes.
33 | Your app is ready to be deployed! 34 | 35 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information. 36 | 37 | ### `npm run eject` 38 | 39 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!** 40 | 41 | If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project. 42 | 43 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own. 44 | 45 | You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it. 46 | 47 | ## Learn More 48 | 49 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started). 50 | 51 | To learn React, check out the [React documentation](https://reactjs.org/). 52 | 53 | ### Code Splitting 54 | 55 | This section has moved here: https://facebook.github.io/create-react-app/docs/code-splitting 56 | 57 | ### Analyzing the Bundle Size 58 | 59 | This section has moved here: https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size 60 | 61 | ### Making a Progressive Web App 62 | 63 | This section has moved here: https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app 64 | 65 | ### Advanced Configuration 66 | 67 | This section has moved here: https://facebook.github.io/create-react-app/docs/advanced-configuration 68 | 69 | ### Deployment 70 | 71 | This section has moved here: https://facebook.github.io/create-react-app/docs/deployment 72 | 73 | ### `npm run build` fails to minify 74 | 75 | This section has moved here: https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify 76 | # business-dashboard 77 | -------------------------------------------------------------------------------- /src/Components/BarchartMonthly.js: -------------------------------------------------------------------------------- 1 | import React, { useState } from 'react'; 2 | import PropTypes from 'prop-types'; 3 | import _ from 'lodash'; 4 | import { 5 | BarChart, 6 | Bar, 7 | XAxis, 8 | YAxis, 9 | CartesianGrid, 10 | Tooltip, 11 | Legend, 12 | ResponsiveContainer 13 | } from 'recharts'; 14 | import { 15 | ButtonDropdown, 16 | DropdownToggle, 17 | DropdownMenu, 18 | DropdownItem 19 | } from 'reactstrap'; 20 | 21 | const BarchartMonthly = props => { 22 | const [dropdownOpen, setOpen] = useState(false); 23 | const [year, setYear] = useState(new Date().getFullYear()); 24 | const toggle = () => setOpen(!dropdownOpen); 25 | 26 | const leaseMonths = props.items.map(item => { 27 | const datesLeases = new Date(item.start_date); 28 | return new Date(datesLeases.getFullYear(), datesLeases.getMonth()); 29 | }); 30 | 31 | const chartData = _.countBy(leaseMonths); 32 | const result = Object.keys(chartData).map(function(key) { 33 | const yearDate = new Date(key); 34 | const monthString = String(yearDate.getMonth() + 1); 35 | const yearString = String(yearDate.getFullYear()); 36 | //const nameDate = parseInt(yearString + monthString.padStart(2, "0")); 37 | const nameString = yearString + '-' + monthString.padStart(2, '0'); 38 | return { 39 | date: yearDate, 40 | labels: nameString, 41 | count: chartData[key] 42 | }; 43 | }); 44 | 45 | result.sort(function(a, b) { 46 | return a.date - b.date; 47 | }); 48 | 49 | //const minYear = result.date.getFullYear(); 50 | //console.log(minYear); 51 | 52 | const dateRangeData = result.filter((item) => { 53 | const dateItem = new Date(item.date); 54 | return (dateItem.getFullYear() >= year && dateItem.getFullYear() < year + 1) 55 | }) 56 | 57 | 58 | return ( 59 | 60 |
