使用 Aspose.Slides for C++ 建立或更新 PowerPoint 簡報圖表

概覽

本文提供了使用 Aspose.Slides for C++ 建立與自訂圖表的完整指南。您將學習如何以程式方式將圖表加入投影片、填入資料,並套用各種格式設定以符合特定設計需求。整篇文章透過詳細的程式碼範例說明每一步,從初始化簡報與圖表物件,到設定類別、座標軸與圖例。遵循本指南,您將能在 C++ 應用程式中整合動態圖表產生,簡化資料驅動簡報的製作流程。

建立圖表

圖表可協助人們快速視覺化資料,並從中獲得在表格或試算表中不易立即看出的見解。

為何建立圖表?

使用圖表,您可以:

  • 在單一投影片中彙總、濃縮或概括大量資料;
  • 顯示資料中的模式與趨勢;
  • 推斷資料隨時間或特定測量單位的方向與動能;
  • 發現異常值、偏差、錯誤與不合理資料;
  • 傳達或呈現複雜資料。

在 PowerPoint 中,您可以透過 插入 功能建立圖表,該功能提供多種圖表範本供設計使用。使用 Aspose.Slides,您可以建立一般圖表(基於常見圖表類型)以及自訂圖表。

建立群集柱狀圖

此範例使用 AddChart 建立一個群集柱狀圖,比較兩條系列於三個類別的資料。系列使用紅色與綠色填圖,個別標籤示範類別名稱、系列名稱與數值。工作表索引 0 代表嵌入式圖表活頁簿中的第一張工作表。

建立散佈圖

散佈圖(亦稱散點圖或 X–Y 圖)常用於檢查模式或展示兩個變數之間的相關性。

在以下情況使用散佈圖:

  • 您有成對的數值資料。
  • 您有兩個相互關聯的變數。
  • 您想判斷兩個變數是否相關。
  • 您有一個自變數對應多個因變數值。

此範例繪製兩組 X–Y 值。第一條系列使用直線與星形標記,第二條系列使用平滑線與圓形標記;兩者皆採用大小為 10 的標記,透過 set_Size 設定。set_Symbol 方法控制標記形狀。

建立圓餅圖

圓餅圖最適合用來顯示資料的部分與整體關係,特別是當資料包含具數值的分類標籤時。然而,若資料的部份或標籤過多,建議改用長條圖。

此範例建立一個包含三個季節值的圓餅圖。每個切片都有自訂的填充與邊框,標籤顯示不同的值、百分比與系列資訊。set_FirstSliceAngle 方法將第一切片起始角度設為 180 度。

欲改善圓餅圖外部標籤的可讀性,請參考 格式領導線 中示範如何調整標籤位置並自訂線條的顏色、寬度、透明度與虛線樣式。

建立折線圖

折線圖(亦稱線圖)最適合用於展示隨時間變化的數值。在折線圖中,您可以一次比較大量資料、追蹤變化與趨勢、突顯系列中的異常等。

此範例使用 AddChart 建立一個預設系列與類別的折線圖,然後將簡報另存為 PPTX。

建立樹狀圖

樹狀圖最適合用於銷售資料,能顯示資料類別的相對大小,並快速凸顯每個類別中貢獻較大的項目。

此範例建立一個包含八個葉節、四個幹節與兩個分支的樹狀圖。SetGroupingItem 方法在分組層級 1 指派幹節,層級 2 指派分支。值決定矩形的相對大小,類別標籤與父層標籤說明階層結構。

建立瀑布圖

瀑布圖顯示正向與負向變化如何共同形成最終值。例如,利潤分解可以從營收開始,扣除成本,再加上其他收入。變化柱在前一值與新值之間浮動,總計柱則從零延伸至累積值。

以下範例使用千美元為單位:

類別 工作簿值 欄位類型
收入 1000 增加
銷售成本 -400 減少
毛利 600 中間總計
營運費用 -200 減少
其他收入 50 增加
淨利 450 最終總計

若要將某點標記為中間或最終總計,請以 true 呼叫其 set_SetAsTotal 方法。於該點的活頁簿儲存格填入實際累積金額:毛利為 600(1000 - 400),淨利為 450(600 - 200 + 50)。此方法僅將欄位標記為總計,並不會計算或填入儲存格值。請勿使用零作為佔位符或為總計點提供其他變化。總計欄會顯示累積值,且不會再次加到執行值上。

完整的 C++ 範例使用 ChartType 中的 Waterfall 成員,清除預設資料,填入嵌入式活頁簿。工作表索引 0 代表第一個工作表;A 欄為類別名稱,B 欄為數值。每個數值儲存格透過 AddDataPointForWaterfallSeries 加入。零基點索引 2 與 5 分別代表中間與最終總計。將 true 傳給 set_ShowValue 可在欄位上顯示金額。此範例不需要輸入簡報或活頁簿。

建立股價圖

股價圖用於顯示開盤價、最高價、最低價與收盤價等金融資料,協助分析市場走勢與波動。它提供關鍵的股價表現洞察,協助投資人與分析師作出明智決策。

此範例建立一個依序為開盤、最高、最低、收盤的 OHLC 圖,包含四條系列與三個類別。set_HasUpDownBars 方法啟用上下條, get_HiLowLinesFormat 控制顯示價格區間的高低線;個別系列線條與次要水平格線則隱藏。

建立箱形圖與鬍鬚圖

箱形圖與鬍鬚圖用於透過中位數、四分位數與可能的異常值,顯示資料的分佈情況。它們在探索性資料分析與統計研究中特別有用,能快速了解資料變異性並辨識異常情形。

此範例從六個數值建立箱形圖與鬍鬚圖。set_QuartileMethod 方法選擇排除法四分位數計算。範例同時啟用平均線、平均標記、內點與離群點。

建立直方圖

直方圖顯示數值在區間(箱子)之間的分佈情形。對於每月訂單處理時間的報告,使用相同的箱寬與門檻可保持區間一致,讓分佈更易於比較。

對水平座標軸呼叫 set_AggregationType,並傳入來源自 AxisAggregationType 的模式。set_BinWidth 僅適用於 ByBinWidth;set_NumberOfBins 只適用於 ByNumberOfBins。使用 Automatic 可讓圖表自行決定箱子。

使用固定箱寬

此範例將處理時間分為 10 分鐘的區間,並為 ≤10 分鐘與 >40 分鐘的情況分別設定獨立的下溢與上溢箱。透過 set_IsUnderflowBin 與 set_IsOverflowBin 啟用這兩個箱子。若要以明確的門檻設定,請分別呼叫 set_UnderflowBin 與 set_OverflowBin,再以 false 呼叫 set_IsAutomaticUnderflowBin 與 set_IsAutomaticOverflowBin。

在 PowerPoint 中顯示的簡報呈現箱子計數 3、4、4、4、2。下溢箱包含 5、10、10,因此其門檻為含等號。上溢箱僅包含 41、50,其門檻為不含等號;40 仍屬於前一區間。內部箱子包含大於下界且小於或等於上界的值。

直方圖(10 分鐘箱寬)與明確的下溢與上溢門檻

指定箱子數量

若需固定細節層級而非固定區間,請為相同資料要求五個箱子。此範例關閉下溢與上溢箱。圖表根據資料範圍自行決定寬度,因而在不同報告間可能改變界限。

建立雷達圖

雷達圖用於以二維形式展示多變量資料,讓多個變數可同時輕鬆比較。它們特別適合辨識多項績效指標或屬性間的模式、優勢與弱點。

此範例使用 AddChart 建立一個預設系列與類別的雷達圖,然後將簡報另存為 PPTX。

建立多類別圖表

多類別圖表用於展示涉及多個類別分組的資料,讓您能同時比較多維度的數值。當需要分析複雜、多層次資料集的趨勢與關係時,此類圖表特別有用。

此範例建立一個群集柱狀圖,具有四對八個類別。透過 SetGroupingItem 方法在分組層級 1 為每對類別設定共同標籤,產生同時顯示單獨標籤與群組標籤的類別軸。

建立地圖圖表

地圖圖表用於以國家、州或城市等特定位置映射資訊,協助視覺化地理資料。它們在分析區域趨勢、人口統計與空間分佈時特別有價值,且具備清晰、具吸引力的視覺呈現。

此範例使用 AddChart 建立一個預設地理資料的地圖圖表,並儲存以供 PowerPoint 檢視。

建立組合圖表

組合圖(或稱混合圖)在同一張圖表中結合兩種或以上的圖表類型。此圖表可協助您突顯、比較或檢視多組資料之間的差異,從而找出它們的關聯性。

組合圖表

此範例將兩個群集柱狀系列與一條折線系列在四個類別上結合。柱狀使用主要垂直座標軸,而 set_PlotOnSecondAxis 將折線放置於右側的次要垂直座標軸。輔助函式負責設定標題、圖例、座標軸標籤與格線。

更新圖表

Aspose.Slides for C++ 讓您可以透過修改圖表資料、格式與樣式來更新 PowerPoint 圖表。此功能簡化了保持簡報隨動態內容更新的程序,確保圖表正確反映最新資料與視覺標準。

此範例更新現有簡報第一張投影片中名為「My chart」的圖表。它需要兩個欄系列,每個系列各三個資料點,類別標籤位於 A 欄,系列名稱位於第一張工作表的第一列。範例使用 GetCell 變更活頁簿儲存格,更新系列值,新增第三個系列,並透過 set_Type 將圖表改為群集圓柱。

設定圖表的資料範圍

若要檢視現有圖表已使用的範圍,請參閱 檢索圖表的資料範圍。

Aspose.Slides for C++ 提供彈性,讓您能從工作表指定特定資料範圍作為圖表資料來源。這表示您可以直接對應工作表的某一區段至圖表,掌控哪些儲存格貢獻於圖表的系列與類別。如此一來,您能輕鬆更新與同步圖表,使其與工作表最新的資料變更保持一致,確保 PowerPoint 簡報反映當前且正確的資訊。

此範例使用 SetRange 將名為「My chart」的圖表(位於現有簡報第一張投影片)之資料來源設定為 Sheet1!A1:B4。圖表活頁簿必須包含此工作表,且該範圍需有第一列的系列標題、A 欄的類別標籤,以及 B 欄的三個數值。

在圖表中使用預設標記

當您在圖表中使用預設標記時,每條系列會自動獲得不同的預設標記符號。

此範例使用 AddChart 建立一個包含兩條折線系列與圖例的圖表。get_Marker 設定保留自動指派的標記符號。第一條系列包含負值與缺失值(以 nullptr 表示),第二條系列則為每個類別都有數值。

常見問題

Aspose.Slides for C++ 支援哪些圖表類型?

Aspose.Slides for C++ 支援廣泛的圖表類型,包括長條圖、折線圖、圓餅圖、面積圖、散佈圖、直方圖、雷達圖等。此彈性讓您能依資料視覺化需求選擇最合適的圖表類型。

如何在投影片中新增圖表?

先建立 Presentation 類別的實例,依索引取得目標投影片,然後呼叫新增圖表的方法,指定圖表類型與初始資料。此流程可直接將圖表整合至簡報中。

如何更新圖表中顯示的資料?

您可以存取圖表的資料活頁簿(IChartDataWorkbook),清除任何預設的系列與類別,然後加入自訂資料。這使您能以程式方式重新整理圖表,以反映最新資料。

是否可以自訂圖表的外觀?

可以,Aspose.Slides for C++ 提供廣泛的自訂選項。您可以修改顏色、字型、標籤、圖例與其他格式元素,以符合特定設計需求。
