如何在Excel图表中设置系列不可见
在Excel图表中，你可以右键点击图表，选择"选择数据"，在弹出窗口中，通过勾选或取消勾选系列来设置是否显示该系列。你可以下载下面的示例文件，在Excel中操作实现此功能。接下来，我们将告诉你如何使用Aspose.Cells库实现此功能。
如何使用Aspose.Cells设置系列不可见
我们使用以下代码来将系列设置为不可见：
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Aspose.Cells Example - Modify Chart Series Color Variation</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>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat } = AsposeCells;
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).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 from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access the first worksheet and its charts
const charts = workbook.worksheets.get(0).charts;
const chart = charts.get("Chart 1");
// Access filtered NSeries and NSeries collections (properties instead of getters)
const nSeriesFiltered = chart.filteredNSeries;
const nSeries = chart.nSeries;
// Set IsColorVaried on series (converted from setIsColorVaried to property assignment)
nSeries.get(1).isColorVaried = true;
nSeries.get(0).isColorVaried = true;
// Save the modified workbook and provide 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.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully! Click the download link to get the modified file.</p>';
});
</script>
</html>
如下图所示，原本可见的前两个系列在输出文件中变成了隐藏。
