تنسيق البيانات في الرسوم البيانية
ضبط بيانات الرسم البياني
هناك نوعان من البيانات التي يتعين التعامل معها أثناء العمل على الرسوم البيانية باستخدام Aspose.Cells وهي كما يلي:
بيانات الرسم البياني
بيانات الرسم البياني هي البيانات التي نستخدمها كمصدر بيانات لإنشاء الرسوم البيانية. يمكننا إضافة نطاق الخلايا (التي تحتوي على بيانات الرسم البياني) عن طريق استدعاء Add طريقة SeriesCollection.

// The path to the documents directory. | |
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); | |
// Adding a sample value to "B3" cell | |
cells.get("B3").setValue(50); | |
// Adding a sample value to "B4" cell | |
cells.get("B4").setValue(40); | |
// Adding a sample value to "C1" cell as category data | |
cells.get("C1").setValue("Q1"); | |
// Adding a sample value to "C2" cell as category data | |
cells.get("C2").setValue("Q2"); | |
// 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."); |
بيانات الفئة
تستخدم بيانات التصنيف لوضع العلامات على بيانات الرسم البياني ويمكن إضافتها إلى SeriesCollection باستخدام طريقته setCategoryData.
