En nuestros temas anteriores, ya proporcionamos muchos ejemplos para demostrar cómo puede configurar una fuente de datos para su gráfico, pero en este tema, proporcionaremos más detalles sobre los tipos de datos que se pueden configurar para un gráfico.
Configuración de los datos del gráfico
Hay dos tipos de datos con los que lidiar al trabajar en gráficos usando Aspose.Cells de la siguiente manera:
Datos del gráfico
Los datos de gráficos son los datos que usamos como fuente de datos para construir nuestros gráficos. Podemos agregar un rango de celdas (que contienen datos del gráfico) llamando alSerieColección objetosAgregar método.

String dataDir = Utils.getSharedDataDir(SettingChartsData.class) + "charts/"; | |
// Instantiating a Workbook object | |
Workbook workbook = new Workbook(); | |
WorksheetCollection worksheets = workbook.getWorksheets(); | |
// Obtaining the reference of the first worksheet | |
Worksheet worksheet = worksheets.get(0); | |
Cells cells = worksheet.getCells(); | |
// Adding a sample value to "A1" cell | |
cells.get("A1").setValue(50); | |
// Adding a sample value to "A2" cell | |
cells.get("A2").setValue(100); | |
// Adding a sample value to "A3" cell | |
cells.get("A3").setValue(150); | |
// Adding a sample value to "A4" cell | |
cells.get("A4").setValue(200); | |
// Adding a sample value to "B1" cell | |
cells.get("B1").setValue(60); | |
// Adding a sample value to "B2" cell | |
cells.get("B2").setValue(32); | |

cells.get("B3").setValue(50); | |
// Adding a sample value to "B4" cell | |
cells.get("B4").setValue(40); | |

// Adding a sample value to "C3" cell as category data | |
cells.get("C3").setValue("Y1"); | |
// Adding a sample value to "C4" cell as category data | |
cells.get("C4").setValue("Y2"); | |
// Adding a chart to the worksheet | |
ChartCollection charts = worksheet.getCharts(); | |
// Accessing the instance of the newly added chart | |
int chartIndex = charts.add(ChartType.COLUMN, 5, 0, 15, 5); | |
Chart chart = charts.get(chartIndex); | |
// Adding NSeries (chart data source) to the chart ranging from "A1" | |
// cell to "B4" | |
SeriesCollection nSeries = chart.getNSeries(); | |
nSeries.add("A1:B4", true); | |
// Setting the data source for the category data of NSeries | |
nSeries.setCategoryData("C1:C4"); | |
workbook.save(dataDir + "SettingChartsData_out.xls"); | |
// Print message | |
System.out.println("Workbook with chart is created successfully."); |
Datos de categoría
Los datos de categoría se utilizan para el etiquetado de los datos del gráfico y se pueden agregar aSerieColección usando susetCategoryDatamétodo.
