Configuring Chart Appearance

Britecharts provides various configuration options to customize the chart’s appearance. Here are some examples:

  
    lineChart.xAxisLabel('Time');
    lineChart.yAxisLabel('Value');
    lineChart.width(800);
    lineChart.height(400);
    lineChart.margin({left: 50, right: 20, top: 20, bottom: 50});
  

Handling Data

Data handling is straightforward with Britecharts. Here is an example of how to structure and load data:

  
    const data = [

      ...
    ];
    lineChart.gradient(['#6E94FC', '#AFB6FC']);

    lineChart.on('customMouseOver', lineTooltip.show);
    lineChart.on('customMouseMove', lineTooltip.update);
    lineChart.on('customMouseOut', lineTooltip.hide);
    d3.select('.js-line-chart-container').datum(data).call(lineChart);
