Manage X and Y Axes

In Excel chart, horizontal and vertical axes are the two most popular axes to use.

The following code snippet demonstrates how to set the options of X and Y axes.

const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "chart_axes.xlsx");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Adding a new worksheet to the Workbook object
const sheetIndex = workbook.getWorksheets().add();

// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(sheetIndex);

// Adding sample values to cells
worksheet.getCells().get("A1").putValue("Series1");
worksheet.getCells().get("A2").putValue(50);
worksheet.getCells().get("A3").putValue(100);
worksheet.getCells().get("A4").putValue(150);
worksheet.getCells().get("B1").putValue("Series2");
worksheet.getCells().get("B2").putValue(60);
worksheet.getCells().get("B3").putValue(32);
worksheet.getCells().get("B4").putValue(50);

// Adding a chart to the worksheet
const chartIndex = worksheet.getCharts().add(AsposeCells.ChartType.Column, 5, 0, 15, 5);

// Accessing the instance of the newly added chart
const chart = worksheet.getCharts().get(chartIndex);
// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B4"
chart.setChartDataRange("A1:B4", true);

// Hiding X axis
chart.getCategoryAxis().setIsVisible(false);

// Setting max value of Y axis
chart.getValueAxis().setMaxValue(200);
// Setting major unit
chart.getValueAxis().setMajorUnit(50);

// Save the file
workbook.save(filePath);
