Esempio

Nell'esempio di codice seguente viene illustrato come aggiungere una riga di soglia dopo che il controllo Chart è stato aggiunto all'area di progettazione.The following code example demonstrates how to add a threshold line after the chart control has been added to the design surface. Il grafico utilizza una striscia non ricorrente per visualizzare un calcolo della media di tutti i punti dati di una serie.The chart uses a non-recurring strip line to show a calculation of the mean of all data points in a series.

Commenti

Quando questa proprietà è impostata su un valore di Auto , il testo è orientato in base al tipo di grafico.When this property is set to a value of Auto, the text is oriented based on the chart type. Per tutti i tipi di grafico X-Y diversi dalla barra, il testo della striscia dell'asse X è orientato orizzontalmente da sinistra a destra nella parte inferiore della striscia.For all X-Y chart types other than Bar, X-axis strip line text is oriented horizontally from left to right on the bottom of the strip line. Per i grafici a barre, il testo della striscia dell'asse X è orientato verticalmente dall'alto verso il basso a destra della striscia.For Bar charts, X-axis strip line text is oriented vertically from top to bottom to the right of the strip line.
