Disable Text Wrapping for Data Labels on the Chart with JavaScript via C++

Microsoft Excel 2013 allows users to wrap or unwrap text inside the data labels of a chart. By default, the text inside the data labels of a chart is in the wrapped state.

Aspose.Cells provides a DataLabels.isTextWrapped() property that you can set to true or false to enable or disable text wrapping of data labels, respectively.

The code sample below shows how to disable text wrapping for the data labels of the chart.

        <title>Aspose.Cells Example</title>
    </head>
    <body>
        <h1>Disable Data Label Text Wrapping</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            if (!fileInput.files.length) {
                document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Instantiating a Workbook object by loading the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Access the first worksheet
            const worksheet = workbook.worksheets.get(0);

            // Access the first chart inside the worksheet
            const chart = worksheet.charts.get(0);

            // Disable the text wrapping of data labels in all series
            chart.nSeries.get(0).dataLabels.isTextWrapped = false;
            chart.nSeries.get(1).dataLabels.isTextWrapped = false;
            chart.nSeries.get(2).dataLabels.isTextWrapped = false;

            // Save the workbook and provide a download link
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'Output_out.xlsx';
            downloadLink.style.display = 'block';
