我有一系列包含兩種行類型的座標。資料分為三個欄位：Column1（x 座標）、Column2（y 座標）和類型。
在雙變量分析中繪製它們並在兩組坐標周圍繪製一個橢圓後，我想在每個組的中心添加一個標記，標記每組坐標的質心。標記最好與“類型”列確定的顏色相符。
我可以在圖表下方的統計數據中看到我需要的值，它是每個組的 Column1 的平均值和 Column2 的平均值，但我不知道如何使用彩色標記將它們添加到圖表中。對於下圖，我手動添加了兩個“+”作為文本，但當我需要多次嘗試多個組時，這變得很麻煩。
也許是這樣的
Seemed easier to find the markers on a black background.在黑色背景上似乎更容易找到標記。
// this is an imperfect solution; the added marker color and position is static and
// will not respond to changes. It also depends on the organization of the displayboxes
// in the report.
oldpref = getpreference(Continuous Color Theme( )); // remember the old color pref
setpreference(Continuous Color Theme( "Spectral" )); // set a more obvious color change
bc=open("$sample_data/big class.jmp");
// make a graph with density ellipses for each age
bv = bc<

在我看來，它看起來像這樣：
Marker Size( 6 );
Marker(
1,
{Col Mean( :Column 1, :Type == "Type1" ),
Col Mean( :Column 2, :Type == "Type1" )}
);
Marker(
1,
{Col Mean( :Column 1, :Type == "Type2" ),
Col Mean( :Column 2, :Type == "Type2" )}
);
然而該解決方案仍然需要每組添加一個標記。
有什麼方法可以新增「類型」列中包含的所有群組的所有標記嗎？
如何繼續使用分析中使用的相同顏色主題？
然而，這只是滿足我需要的一個簡單例子。通常我會有數十個需要添加到視覺化中的質心。在我的實際分析中，由於我需要繪製質心的可能類別數量太多，它很快就變得痛苦起來。
也許有一種方法可以添加這樣的座標，而無需手動向表中添加行。
有沒有辦法繪製類型分析計算出的平均值，避免手動繪圖？
或者甚至在 Graph Builder 中也沒關係，只要避免手動新增行（標記）。
只需在資料表中新增質心的座標和類型作為兩個新行。將其行狀態變更為排除、紅色或藍色以及「+」標記。
