單擊“保存”，將顯示“導出圖形”對話(huà)框。如果文件已經(jīng)存在，單擊“保存”時(shí)會(huì )詢(xún)問(wèn)是否要替換該文件。導出圖形對話(huà)框允許您選擇：?要導出的通道。請注意，未監測或記錄的通道呈灰色。?要導出多少樣本。?是否導出原始樣本或顯示的點(diǎn)。此外，您還可以編輯或添加注釋。趨勢驅動(dòng)窗口2 6-117如果選擇第一個(gè)或最后一個(gè)，將顯示一個(gè)額外的采樣字段。如果選擇范圍，將顯示兩個(gè)附加字段（從和到）。請注意，選擇“全部”或“可見(jiàn)”也會(huì )將“采樣數”、“從”和“到”字段更改為相應的（全部或可見(jiàn)）采樣數以及開(kāi)始和結束點(diǎn)，盡管這些字段未顯示。此外，更改測量/顯示會(huì )更改“采樣”字段，無(wú)論其是否可見(jiàn)。因此，在選擇第一個(gè)/最后一個(gè)/范圍和測量/顯示后，最好編輯“采樣”或“從”和“到”字段。注意，注釋實(shí)際上由一行組成，盡管它在編輯字段中自動(dòng)換行和滾動(dòng)。按下Enter鍵實(shí)際上與單擊OK按鈕相同。編輯時(shí)，可以使用普通的Windows快捷鍵和編輯鍵，如箭頭鍵、Home鍵、End鍵、Del鍵等，也可以使用Ctrl鍵和/或Shift鍵。但是，請注意，按Esc鍵與單擊“取消”按鈕相同。準備就緒后，單擊“確定”。如果要取消操作，請單擊“取消”按鈕。趨勢6-118 DriveWindow 2 12.2.1導出的趨勢示例注意，無(wú)論導出的是監視器還是數據記錄器，導出文件的內容都非常相似。導出測量的監視器與其他監視器最為不同，因為每個(gè)導出通道的每個(gè)樣本都會(huì )導出時(shí)間戳。以下顯示了兩個(gè)測量的監測器通道的輸出。趨勢驅動(dòng)窗口2 6-119當導入（打開(kāi)）Excel并調整通道寬度時(shí)，結果是：前兩行包含文件標識標簽和注釋。接下來(lái)的兩行顯示在“導出圖形”對話(huà)框中所做的選擇。一條空行將它們與包含監控變量以外的監控設置的七行分隔開(kāi)，但包括x軸原點(diǎn)的時(shí)間。頻道設置遵循空行。在它們后面有一個(gè)空行和一個(gè)標題行。其余部分包含時(shí)間戳和未縮放的監控值。注意，時(shí)間戳是相對于x軸原點(diǎn)的。趨勢6-120 DriveWindow 2以下顯示了所示相同兩個(gè)監視器通道的導出。Trends DriveWindow 2 6-121當導入（打開(kāi)）Excel并調整通道寬度時(shí)，結果是：文件的開(kāi)頭包含與測量導出情況相同的信息。但是，結束部分不包括時(shí)間戳，但所有通道值都有一個(gè)共同的時(shí)間。這些值也會(huì )縮放。趨勢6-122驅動(dòng)窗口2以下顯示了測量的兩個(gè)數據記錄器通道的輸出。Trends DriveWindow 2 6-123當導入（打開(kāi)）Excel并調整通道寬度時(shí)，結果是：文件的開(kāi)頭包含與監視器導出情況類(lèi)似的信息，如圖所示。然而，存在差異。文件標識標簽還包含數據記錄器的OPC地址。沒(méi)有x軸原點(diǎn)時(shí)間。
Click Save and an Export Graph dialog box is presented. If the file already exists, confirmation to replace it asked, when you click Save. The Export Graph dialog box allows you to select: ? Which of the channels to export. Note that channels not monitored or logged are grayed. ? How many samples to export. ? Whether to export the raw samples or shown points. In addition, you can edit or add a comment. Trends DriveWindow 2 6-117 If you select first or last, an additional Samples field is shown. If you select range, two additional fields (From and To) are shown. Note that selecting all or visible also changes the Samples, From, and To fields to corresponding (all or visible) number of samples and to starting and ending point, although the fields are not shown. Also, changing measured/shown changes the Samples field, whether it is visible or not. So, it is better to edit the Samples or From and To fields after selecting the first/last/range and measured/shown. Note that the comment actually consists of one line, although it automatically wraps and scrolls within the edit field. Pressing the Enter key is actually the same as clicking the OK button. While editing, you can use the normal Windows shortcut and editing keys like the arrow keys, Home, End, Del, etc. keys, with or without Ctrl and/or Shift key down. Note, however, that pressing the Esc key is same than clicking the Cancel button. When you are ready, click OK. If you want to cancel the operation, click the Cancel button. Trends 6-118 DriveWindow 2 12.2.1 Examples of exported trends Note that contents of the exported files are quite similar, whether the monitor or a datalogger is exported. Exporting the monitor as measured differs most from the others, because the time stamp is exported for each sample of each exported channel. The following shows exporting of two monitor channels as measured. Trends DriveWindow 2 6-119 When imported (opened) into Excel and adjusting widths of channels, the result is: The first two lines contain the file identification tag and the comment. The next two lines show the selections made in the Export Graph dialog box. An empty line separates them from the seven lines containing monitor settings other than monitored variables, but including the time at x-axis origin. The channel settings follow an empty line. After them there is an empty line and a title line. The rest contains the time stamps and unscaled monitored values. Note that the time stamps are relative to the x-axis origin. Trends 6-120 DriveWindow 2 The following shows exporting of the same two monitor channels as shown. Trends DriveWindow 2 6-121 When imported (opened) into Excel and adjusting widths of channels, the result is: The beginning of the file contains the same information as in case the export was done as measured. The end part, however, does not include time stamps, but there is a common time for all channel values. The values are scaled, too. Trends 6-122 DriveWindow 2 The following shows exporting of the two datalogger channels as measured. Trends DriveWindow 2 6-123 When imported (opened) into Excel and adjusting widths of channels, the result is: The beginning of the file contains the similar information as in case the monitor export was done as shown. There are differences, however. The file identification tag contains also the OPC address of the datalogger. There is no x-axis origin time.
