チャート:グリッド線と目盛り

デフォルトでは、FlexChartは水平線を使用して、x軸とy軸に沿った主要なグリッド線を表示します。これにより、チャートがきれいになり、読みやすくなります。

これを変更するには、axisXaxisYプロパティを変更します。この例では、両方の軸に沿って主グリッド線と副マイナーグリッド線を作成および制御する方法と、CSSを使用してグリッド線をカスタマイズする方法を示します。

import 'bootstrap.css'; import '@mescius/wijmo.styles/wijmo.css'; import './styles.css'; import { FlexChart, Palettes } from '@mescius/wijmo.chart'; import { isArray, toggleClass } from '@mescius/wijmo'; import { getData } from './data'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // create the chart let theChart = new FlexChart('#theChart', { axisX: { format: 'm', majorGrid: true, majorTickMarks: 'Cross', majorUnit: 7, minorGrid: true, minorTickMarks: 'None', minorUnit: 1, }, axisY: { min: 790, max: 860, format: 'c0', axisLine: true, majorGrid: true, majorTickMarks: 'Cross', majorUnit: 20, minorGrid: true, minorTickMarks: 'None', minorUnit: 5, }, itemsSource: getData(), bindingX: 'date', chartType: 'Candlestick', series: [ { binding: 'high,low,open,close', name: 'Alphabet Inc' } ], legend: { position: 'None' } }); theChart.palette = getRandomPalette(); // // toggle custom CSS, grid visibility onCheck('customGridlines', (checked) => toggleClass(theChart.hostElement, 'custom-gridlines', checked)); onCheck('x-major', (checked) => theChart.axisX.majorGrid = checked); onCheck('x-minor', (checked) => theChart.axisX.minorGrid = checked); onCheck('y-major', (checked) => theChart.axisY.majorGrid = checked); onCheck('y-minor', (checked) => theChart.axisY.minorGrid = checked); // onCheck('customUnits', (checked) => { if (checked) { theChart.axisX.majorUnit = 7; theChart.axisX.minorUnit = 1; theChart.axisY.majorUnit = 20; theChart.axisY.minorUnit = 5; } else { theChart.axisX.majorUnit = null; theChart.axisX.minorUnit = null; theChart.axisY.majorUnit = null; theChart.axisY.minorUnit = null; } }); // function onCheck(id, fn) { document.getElementById(id).addEventListener('click', e => { fn(e.target.checked); }); } } // function getRandomPalette() { let palettes = Object.keys(Palettes).filter(prop => isArray(Palettes[prop])); let rand = Math.floor(Math.random() * palettes.length); // return Palettes[palettes[rand]]; }
