6查看监视器和数据记录器趋势非常相似。您可以水平和垂直滚动。可以向内、向外缩放和重置缩放。您可以使用图形光标检查趋势。您可以临时更改选定图形光标数值的显示格式。您还可以在查看趋势时更改设置，如x轴长度、y最小值和最大值以及缩放（仅限数据记录器）。趋势DriveWindow 2 6-7 7保存和恢复自DriveWindow版本2.10以来，可以保存和恢复趋势。8打印和导出监视器和数据记录器趋势都可以打印、复制到剪贴板并导出（以数字文本格式）。另请参阅：窗口区域浏览树窗格趋势设置窗格趋势显示窗格2.常见趋势设置监视器和记录器具有以下常见设置，这些设置会影响相应趋势的显示：•X轴长度（秒）•Y轴最小值和最大值•Y轴自适应，这实际上只是改变y轴最小值和最大值的另一种方式。•不同通道的缩放比例除了一些例外，所有这些都可以随时改变：•只有在趋势显示窗格中绘制趋势时，y轴才能调整。•监视器运行时，无法更改监视器通道不同通道的缩放比例。笔记更改监视器通道的缩放比例要求从开始重新绘制监视器趋势。如果您有大量监控数据，这可能需要很长时间。公用设置将保存到工作空间中并从工作空间中恢复。另请参阅：监视器和数据记录器趋势设置窗格监视器菜单数据记录器菜单恢复默认设置2.1设置X轴长度您可以随时设置监视器或数据记录器的X轴长度。注意，缩放通常也会改变x轴长度。上传数据记录器时，数据记录器的X轴长度也可以自动更改。如果x轴长度大于数据记录器通道缓冲区的大小，如果它小于间隔，或者不是间隔的倍数，x轴长度将自动设置为数据记录器通道缓冲器的大小。请注意，如果从未上载数据记录器，DriveWindow无法确定数据记录器通道缓冲区的大小。因此，DriveWindow不会对x轴长度进行任何检查，直到它了解更多有关数据记录器的信息。当数据记录器通道缓冲区的大小已知时，DriveWindow不接受不正确的x轴长度设置。然而，当数据记录器间隔改变时，未检查x轴长度，因此可能具有不正确的值。在这种情况下，数据记录器的上传会自动设置x轴长度。趋势6-8 DriveWindow 2注意，改变x轴长度仅影响当前缩放级别。向外缩放或缩放重置将恢复先前或基本级别的x轴设置。要更改x轴长度，请双击趋势设置窗格中的x轴长度字段，或在轴子菜单中选择x轴长度命令，该命令可以在监视器、监视器设置的上下文菜单、数据记录器菜单和数据记录器设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.
