图表创建(WPS JS API)

⚠️ 重要:WPS 加载项中创建图表必须使用 ws.Shapes.AddChart2() 方法! ❌ 禁止使用 ws.ChartObjects.Add()(WPS 中不支持此方法)

AddChart2(Style, XlChartType, Left, Top, Width, Height) 参数:

  • Style:图表样式编号(必须用 0 或正整数,禁止 -1)
  • XlChartType:4=xlLine(折线), 51=xlColumnClustered(柱状), 5=xlPie(饼图), 54=xlColumnStacked(堆叠柱状)
  • Left/Top/Width/Height:位置和大小(像素)

不支持的图表类型(会崩溃或空白)

  • ❌ K线图/蜡烛图/OHLC (88/89/90) — WPS 不支持
  • ❌ 股价图 (88/89/90) — WPS 不支持
  • 股价数据请改用折线图(收盘价走势)+ 柱状图(成交量),分两个图表展示

图表最佳实践

  • 每个图表至少 560×320 像素,别太小
  • 多个图表之间留 340px 纵向间距
  • 一个图表只展示一个主题,别把所有数据塞一张图

图表颜色和样式

创建图表后,必须为每条数据系列单独设置颜色,避免默认灰色:

try {
  var dataRange = ws.Range("A1:C20");
  var lastRow = 20;
  var chartTop = (lastRow + 2) * 20;
  var shape = ws.Shapes.AddChart2(0, 4, 20, chartTop, 600, 340);
  var chart = shape.Chart;
  chart.SetSourceData(dataRange);
  chart.HasTitle = true;
  chart.ChartTitle.Text = "趋势分析";

  try {
    chart.SeriesCollection.Item(1).Format.Line.ForeColor.RGB = 0xFF4500;
    chart.SeriesCollection.Item(1).Format.Line.Weight = 2.5;
    chart.SeriesCollection.Item(2).Format.Line.ForeColor.RGB = 0x0000FF;
    chart.SeriesCollection.Item(2).Format.Line.Weight = 2.5;
    chart.SeriesCollection.Item(3).Format.Line.ForeColor.RGB = 0x00AA00;
    chart.SeriesCollection.Item(3).Format.Line.Weight = 2.5;
  } catch(ce) {}

  try {
    chart.SeriesCollection.Item(1).Format.Fill.ForeColor.RGB = 0xE8A040;
  } catch(ce) {}
} catch(e) {
  ws.Range("F1").Value2 = "趋势";
  for (var i = 2; i <= lastRow; i++) {
    var cur = ws.Range("B"+i).Value2, prev = ws.Range("B"+(i-1)).Value2;
    ws.Range("F"+i).Value2 = cur > prev ? "▲" : (cur < prev ? "▼" : "→");
  }
}

图表配色方案(BGR 格式)

用途BGR 颜色值视觉效果
系列1(主线/收盘价)0xFF4500鲜明蓝
系列2(对比线/开盘价)0x0000FF红色
系列3(辅助线/均价)0x00AA00绿色
系列4(参考线)0x00CCFF橙色
柱状图(成交量)0xE8A040金橙色
涨日柱0x0000FF红色
跌日柱0x00AA00绿色

⚠️ 图表代码必须包裹在 try/catch 中。颜色设置也要 try/catch。

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
