Gridlines and Tickmarks

By default, the FlexChart uses horizontal lines to show the x-axis and major gridlines along the y-axis. This makes charts clean and easy-to-read.

You can change this by modifying the axisX and axisY properties. This example shows how you create and control major and minor gridlines along both axes, and how to customize them using CSS.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import * as wjChart from '@grapecity/wijmo.chart'; import * as wjCore from '@grapecity/wijmo'; import { getData } from './data'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // create the chart let theChart = new wjChart.FlexChart('#theChart', { axisX: { format: 'MMM dd', 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) => wjCore.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.getOwnPropertyNames(wjChart.Palettes) .filter(prop => typeof wjChart.Palettes[prop] === "object" && prop !== 'prototype'); let rand = Math.floor(Math.random() * palettes.length); // return wjChart.Palettes[palettes[rand]]; }
