6查看監視器和數據記錄器趨勢非常相似。您可以水平和垂直滾動(dòng)?？梢韵騼?、向外縮放和重置縮放。您可以使用圖形光標檢查趨勢。您可以臨時(shí)更改選定圖形光標數值的顯示格式。您還可以在查看趨勢時(shí)更改設置，如x軸長(cháng)度、y最小值和最大值以及縮放（僅限數據記錄器）。趨勢DriveWindow 2 6-7 7保存和恢復自DriveWindow版本2.10以來(lái)，可以保存和恢復趨勢。8打印和導出監視器和數據記錄器趨勢都可以打印、復制到剪貼板并導出（以數字文本格式）。另請參閱：窗口區域瀏覽樹(shù)窗格趨勢設置窗格趨勢顯示窗格2.常見(jiàn)趨勢設置監視器和記錄器具有以下常見(jiàn)設置，這些設置會(huì )影響相應趨勢的顯示：?X軸長(cháng)度（秒）?Y軸最小值和最大值?Y軸自適應，這實(shí)際上只是改變y軸最小值和最大值的另一種方式。?不同通道的縮放比例除了一些例外，所有這些都可以隨時(shí)改變：?只有在趨勢顯示窗格中繪制趨勢時(shí)，y軸才能調整。?監視器運行時(shí)，無(wú)法更改監視器通道不同通道的縮放比例。筆記更改監視器通道的縮放比例要求從開(kāi)始重新繪制監視器趨勢。如果您有大量監控數據，這可能需要很長(cháng)時(shí)間。公用設置將保存到工作空間中并從工作空間中恢復。另請參閱：監視器和數據記錄器趨勢設置窗格監視器菜單數據記錄器菜單恢復默認設置2.1設置X軸長(cháng)度您可以隨時(shí)設置監視器或數據記錄器的X軸長(cháng)度。注意，縮放通常也會(huì )改變x軸長(cháng)度。上傳數據記錄器時(shí)，數據記錄器的X軸長(cháng)度也可以自動(dòng)更改。如果x軸長(cháng)度大于數據記錄器通道緩沖區的大小，如果它小于間隔，或者不是間隔的倍數，x軸長(cháng)度將自動(dòng)設置為數據記錄器通道緩沖器的大小。請注意，如果從未上載數據記錄器，DriveWindow無(wú)法確定數據記錄器通道緩沖區的大小。因此，DriveWindow不會(huì )對x軸長(cháng)度進(jìn)行任何檢查，直到它了解更多有關(guān)數據記錄器的信息。當數據記錄器通道緩沖區的大小已知時(shí)，DriveWindow不接受不正確的x軸長(cháng)度設置。然而，當數據記錄器間隔改變時(shí)，未檢查x軸長(cháng)度，因此可能具有不正確的值。在這種情況下，數據記錄器的上傳會(huì )自動(dòng)設置x軸長(cháng)度。趨勢6-8 DriveWindow 2注意，改變x軸長(cháng)度僅影響當前縮放級別。向外縮放或縮放重置將恢復先前或基本級別的x軸設置。要更改x軸長(cháng)度，請雙擊趨勢設置窗格中的x軸長(cháng)度字段，或在軸子菜單中選擇x軸長(cháng)度命令，該命令可以在監視器、監視器設置的上下文菜單、數據記錄器菜單和數據記錄器設置的上下文表中找到。
6 Viewing Viewing of the monitor and datalogger trends is quite similar. You can scroll horizontally and vertically. You can zoom inwards, outwards, and reset zooming. You can examine the trends using a graph cursor. You can temporarily change display format of selected graph cursor numerical values. You can also change settings like x-axis length, y minimum and maximum, and scaling (dataloggers only) while viewing a trend. Trends DriveWindow 2 6-7 7 Saving and Restoring Since version 2.10 of DriveWindow, trends can be saved and restored. 8 Printing and Exporting Both monitor and datalogger trends can be printed, copied to clipboard, and exported (in numerical text format). See Also: Window Area Browse Tree Pane Trend Settings Pane Trend Display Pane 2. Common Trend Settings The monitor and the loggers have the following common settings, which affect the displaying of the corresponding trends: ? X-axis length (in seconds) ? Y-axis minimum and maximum ? Y-axis adaptation, which is actually just another way to change y-axis minimum and maximum ? Scaling of different channels With some exceptions, all of these can be changed at any time: ? Y-axis can be adapted only when a trend is drawn in the trend display pane. ? Scaling of different channels of a monitor channel cannot be changed while the monitor is running. Note! Changing of the scaling of a monitor channel requires that the monitor trends are redrawn from the beginning. If you have lot of monitored data, this can take a long time. The common settings are saved into and restored from a workspace. See Also: Monitor and Dataloggers Trend Settings Pane Monitor Menu Datalogger Menu Restoring Default Settings 2.1 Setting X-Axis Length You can set x-axis length of the monitor or a datalogger at any time. Note that zooming usually also changes x-axis length. X-axis length of a datalogger can also change automatically when the datalogger is uploaded. If the xaxis length is bigger than size of the datalogger channel buffer, if it is less than the interval, or if it is not multiple of the interval, x-axis length is automatically set to the size of the datalogger channel buffer. Note that if a datalogger has never been uploaded, DriveWindow does not know for sure the size of a datalogger channel buffer. Thus DriveWindow does not do any checking about the x-axis length, until it knows more about the datalogger. When size of the datalogger channel buffer is known, DriveWindow does not accept improper setting of x-axis length. However, when the datalogger interval is changed, x-axis length is not checked, and thus may have an improper value. In such cases, uploading of the datalogger automatically sets the xaxis length. Trends 6-8 DriveWindow 2 Note that changing x-axis length affects only the current zooming level. Zooming outwards or zooming reset restores the previous or basic level x-axis setting. To change x-axis length, either double-click the X Axis Length (s) field in the trend settings pane, or select X Length command in the Axis submenu, which can be found in the Monitor, context menu of Monitor Settings, Datalogger menu, and context menu of Datalogger Settings.
