Highcharts marked area graph
The following example demonstrates the marked area graph.
In the previous section we already know Highcharts configuration syntax. Let's look at how to configure.
Configuration
Use yAxis.plotBands properties to configure marked area. Interval range use 'from' and 'to' attribute. Color settings using the 'color' property. Label style uses 'label' property.
Configuration information:
var yAxis = { title: { text: 'Wind speed (m/s)' }, min: 0, minorGridLineWidth: 0, gridLineWidth: 0, alternateGridColor: null, plotBands: [{ // Light air from: 0.3, to: 1.5, color: 'rgba(68, 170, 213, 0.1)', label: { text: 'Light air', style: { color: '#606060' } } }, { // Light breeze from: 1.5, to: 3.3, color: 'rgba(0, 0, 0, 0)', label: { text: 'Light breeze', style: { color: '#606060' } } }, { // Gentle breeze from: 3.3, to: 5.5, color: 'rgba(68, 170, 213, 0.1)', label: { text: 'Gentle breeze', style: { color: '#606060' } } }, { // Moderate breeze from: 5.5, to: 8, color: 'rgba(0, 0, 0, 0)', label: { text: 'Moderate breeze', style: { color: '#606060' } } }, { // Fresh breeze from: 8, to: 11, color: 'rgba(68, 170, 213, 0.1)', label: { text: 'Fresh breeze', style: { color: '#606060' } } }, { // Strong breeze from: 11, to: 14, color: 'rgba(0, 0, 0, 0)', label: { text: 'Strong breeze', style: { color: '#606060' } } }, { // High wind from: 14, to: 15, color: 'rgba(68, 170, 213, 0.1)', label: { text: 'High wind', style: { color: '#606060' } } }] };
