In this context, data dashboards (Dashboard) emerged as the times require, which can help people manage and analyze data more easily and achieve data-driven decisions.

What is a data dashboard?

Data dashboard is a data visualization tool that usually displays key indicators, trends, overviews and alerts of data so that users can analyze the data more quickly and intuitively, helping users better understand the data and Make decisions. It can automatically update based on data sources according to user needs, while allowing users to customize and interactive operations to adapt to the needs and goals of different users.

The role of data dashboard

1. Quickly monitor data: Data dashboard can help users quickly summarize and monitor business data without in-depth study of reports and data.

2. Visual data presentation: The data dashboard is a visual tool that can present data to users in the form of graphics, tables, instruments, icons, etc., making it more vivid and intuitive.

3. Integration of multiple data sources: The data dashboard can integrate data from different data sources, so that users can obtain more comprehensive business data through the dashboard and better perform data analysis and decision making.

4. Personalized customization: The dashboard can be customized to meet various personalized needs, such as different data needs between enterprises and departments, and special display methods required by users.

Function of data dashboard

1. Data access: Data access is the first step of the dashboard. Data needs to be obtained through the data source and displayed and displayed in the dashboard. analyze. Different dashboards support different data sources, and common data sources include enterprise databases, statistical tools, Excel files, cloud storage, Web API, etc.

2. Data processing and analysis: Processing and analysis are the core functions of the data dashboard, including data calculation, filtering, statistics, sorting, etc. In addition, it can also be analyzed and compared based on time, region and other factors, and Perform trend prediction and early warning on data.

  1. Data presentation and interaction: Data presentation and interaction are the ultimate goals of the data dashboard. Users can visually present data through graphics, tables, dashboards, etc., and the dashboard also provides Interactive data operations, such as filtering, sorting, searching, etc.
  2. Data sharing and collaboration: Data sharing and collaboration is another function of the data dashboard. It can share and collaborate the results and analysis data produced by the dashboard with teams and partners to optimize through real-time collaboration. decision making.

Chart code examples

The following are some chart code examples for data dashboards, which can help you better understand how to implement the dashboard.

  1. Pie chart
PieChart chart = new PieChartBuilder().width(800).height(600).title("饼状图").build();

chart.addSeries("男", 60);
chart.addSeries("女", 40);

new SwingWrapper(chart).displayChart();
  1. Bar chart
CategoryChart chart = new CategoryChartBuilder().width(800).height(600).title("柱状图").xAxisTitle("X轴").yAxisTitle("Y轴").build();

chart.getStyler().setLegendPosition(Styler.LegendPosition.InsideNW); 
chart.getStyler().setHasAnnotations(true);
chart.getStyler().setStacked(true);

List<String> xAxisData = Arrays.asList("1月", "2月", "3月", "4月", "5月", "6月");
List<Integer> series1 = Arrays.asList(10, 20, 30, 15, 25, 35);
List<Integer> series2 = Arrays.asList(15, 30, 20, 10, 5, 25);

chart.addSeries("A公司", xAxisData, series1);
chart.addSeries("B公司", xAxisData, series2);

new SwingWrapper(chart).displayChart();
  1. Line chart
XYChart chart = new XYChartBuilder().width(800).height(600).title("折线图").xAxisTitle("X轴").yAxisTitle("Y轴").build();

double[] xData = new double[] {0.0, 1.0, 2.0, 3.0, 4.0, 5.0};
double[] yData1 = new double[] {0.0, 1.0, 2.0, 3.0, 4.0, 5.0};
double[] yData2 = new double[] {0.0, 1.5, 2.5, 3.5, 4.5, 5.5};

XYSeries series1 = chart.addSeries("数据1", xData, yData1);
series1.setMarker(SeriesMarkers.CIRCLE);

XYSeries series2 = chart.addSeries("数据2", xData, yData2);
series2.setMarker(SeriesMarkers.SQUARE);

new SwingWrapper(chart).displayChart();
