JHeatChart 是一个 Java 类,用来创建热图图表。
示例代码:
// Create some dummy data. double[][] data = new double[][]{{3,2,3,4,5,6}, {2,3,4,5,6,7}, {3,4,5,6,7,6}, {4,5,6,7,6,5}}; // Create our heat chart using our data. HeatChart chart = new HeatChart(data); // Customise the chart. chart.setTitle("This is my chart title"); chart.setXAxisLabel("X Axis"); chart.setYAxisLabel("Y Axis"); // Output the chart to a file. chart.saveToFile(new File("my-chart.png"));
