Chart Types
A scatter plot is a chart type that displays a set of data points as individual dots or markers, with the x-axis and y-axis representing the two variables being compared. Highcharts supports scatter plots with the chart.type
option set to 'scatter'
.
To create a scatter plot using Highcharts, you can follow these steps:
<script src="https://code.highcharts.com/highcharts.js"></script>
<div id="chart-container"></div>
Highcharts.chart('chart-container', { chart: { type: 'scatter' }, title: { text: 'Scatter Plot' }, xAxis: { title: { text: 'X Axis Label' } }, yAxis: { title: { text: 'Y Axis Label' } }, series: [{ name: 'Series Name', data: [[1, 5], [2, 10], [3, 15], [4, 20], [5, 25]] }] });
In this example, we're creating a scatter plot with the Highcharts chart
function and passing in a set of options:
chart.type
is set to 'scatter'
to create a scatter plottitle.text
is set to 'Scatter Plot'
to set the main titlexAxis.title
is used to set the label for the x-axisyAxis.title
is used to set the label for the y-axisseries
is set to an array of objects with a name
and data
property to define the series data. The data
property contains an array of arrays, where each inner array represents a data point with two values (the x and y coordinates).With these options, you can create a scatter plot with customizable data and appearance. Note that Highcharts supports other options to customize the appearance of scatter plots, including the color
, marker
, and tooltip
options.
Customizing appearance in Highcharts Scatter Plot: To customize the appearance of a Scatter Plot in Highcharts, you can use various options like marker shapes, colors, and more. Here's an example code snippet:
Highcharts.chart('container', { chart: { type: 'scatter' }, plotOptions: { scatter: { marker: { symbol: 'circle', // Change marker shape radius: 8, fillColor: 'rgba(150, 200, 100, 0.7)', lineColor: 'white', lineWidth: 2 } } }, series: [{ name: 'Scatter Plot Data', data: [[10, 20], [30, 40], [50, 60]] }] });
Adding data to Highcharts Scatter Plot:
Adding data to a Scatter Plot involves specifying the x and y coordinates. Use the data
property within the series
object. Here's an example:
series: [{ name: 'Scatter Plot Data', data: [[10, 20], [30, 40], [50, 60]] }]
Grouped Scatter Plot using Highcharts: To create a grouped Scatter Plot, you can use multiple series within the same chart. Here's an example:
series: [{ name: 'Group 1', data: [[10, 20], [30, 40], [50, 60]] }, { name: 'Group 2', data: [[15, 25], [35, 45], [55, 65]] }]
Interactive features in Highcharts Scatter Plot: Highcharts supports interactive features like tooltips, click events, and legends in Scatter Plots. You can enable these features to enhance user interaction. Here's a snippet for tooltip configuration:
tooltip: { pointFormat: 'X: {point.x}, Y: {point.y}' }
Trendlines in Highcharts Scatter Plot:
You can add trendlines to a Scatter Plot using the regression
series type. Here's an example:
series: [{ type: 'scatter', name: 'Scatter Plot Data', data: [[10, 20], [30, 40], [50, 60]] }, { type: 'regression', name: 'Trendline', data: [[10, 20], [30, 40], [50, 60]] }]
Note: Ensure you include the highcharts-regression
module for regression analysis.
