折れ線では、x軸はさまざまなカテゴリを表しますが、散布図のx軸は、x変数の実際の値を表します。
散布図には、水平（x）および垂直（y）の2つの値軸があります。x値とy値を組み合わせて1つのデータポイントとし、これらのデータポイント（クラスタとも呼ぶ）を不規則な間隔で表示します。散布図は通常、科学的、統計的、または工学的なデータなどの数値を表示し、比較するために使用されます。
散布図の種類
散布図：散布図には、選択したデータ範囲に基づくデータポイントが表示されます。これを分析することで、x変数とy変数との間に何らかの関係が存在するかどうかを判定します。
散布図（平滑線とマーカー）：平滑線とマーカー付きの散布図では、各データポイント間が滑らかな曲線で結ばれます。
散布図（平滑線）：平滑線付きの散布図では、各データポイント間が滑らかな曲線で結ばれますが、個々のデータポイントは識別されません。
散布図（直線とマーカー）：直線とマーカー付きの散布図では、各データポイント間が直線で結ばれます。
散布図（直線）：直線付きの散布図では、各データポイント間が直線で結ばれますが、個々のデータポイントは識別されません。
バブルチャート：バブルチャートは散布図の一種ですが、データポイントがバブルによって表現され、3番目の次元がバブルのサイズによって表されます。散布図と同じく、バブルチャートにもカテゴリ軸は使用されません。水平軸と垂直軸の両方が値軸となります。また、バブルチャートにはx値とy値に加えて、z値（バブルのサイズ）がプロットされます。
3つの系列から成るデータがあり、その個々の系列が値で構成される場合には、散布図の代わりにバブルチャートを使用できます。個々のバブルのサイズは、3番目のデータ系列の値によって決まります。バブルチャートは、財務データを表す場合にもしばしば使用されます。バブルの大きさにより、特定の値を視覚的に強調することができます。
マーカーの色、形状、境界線は、「平滑線とマーカー付きの散布図」と「直線とマーカー付き散布図」でカスタマイズできます。
