ggplot pie chart

3.1. Simple pie chart Pie charts must use Defaultpiedataset to provide data for the chart. DefaultPieDataset　dataset　=　new　DefaultPieDataset(); dataset.setValue("Spring　Security",　100); dataset.setValue("jBPM　4",　200); dataset.setValue("Ext　JS",　300); dataset.setValue("JFreeChart",　100); This time we use SetValue to

The goals to be achieved are:1. Bind data to PIE's background data to automatically generate pie charts.2. The resulting pie chart has a detailed description of the text.The specific implementation steps:>> Front-desk interface settings:1. Set the Chart1 property legends the default Legend1 in the Enable to false;2. Set the ChartType of the series to Pie3. Set th

Before you implement the data pie chart, make sure that you have a "db.mdb" database in the root directory of disk C, that the database is already set up, and that you have the data in the article "Implementing the Data bar diagram in the asp.net page." Here's a concrete step in asp.net to implement the data pie chart,

When our software requires various pie charts and bar charts to represent data, we may think of using graphical controls or third-party controls in Offices, but most of the third-party controls need to be registered now, some free controls have developer tags. However, graphical controls using Offices cannot be well controlled in the program, and the ease of use is also low, so here I will show how to use GDI + in C # To connect the

In the previous article, we mentioned how to use keyword to set the Label display format on the pie chart, for example: Chart1.series [0]. Label = "# Valy [# percent]"; At this time, the label is displayed as the size of the Y axis value, and the percentage is displayed in the brackets that follow it. In practice, I found that, without formatting, the corresponding name of the X axis is displayed by defa
