可以通过“删除”命令、“剪切”命令或通过拖放移动来完成删除。请注意，通道设置的选择也可用于从当前数据记录器中删除记录的项目。也可以通过选择删除触发变量。可以通过“删除”命令、“剪切”命令或通过拖放移动来完成删除。笔记许多驱动器要求，如果没有记录所有通道，则记录的通道必须是第一个。DriveWindow通过将记录的项目及其缩放值“向上”移动（如有必要）来处理此问题。它还允许仅将新的记录项目添加到第一个空闲频道。趋势显示窗格包含一个短的垂直滚动条。单击其上的向上或向下箭头也会同时更改Y轴最大值和Y轴最小值。调整Y轴时，Y轴最小值和Y轴最大值也同时改变。用户界面2-72 DriveWindow 2注意，如果未选择有效的数据记录器（例如，在浏览树窗格中选择了打开的参数文件），则除通道之外的所有其他值字段中都显示n/a，通道的设置名称中有n/a，且值（缩放）为空。趋势显示窗格中的数据记录器显示也是空的。用户界面驱动窗口2 2-73如果当前数据记录器未正确初始化，许多值字段显示n/a，所有通道的设置名称中都有n/a，并且值（缩放）为空。趋势显示窗格中的数据记录器显示也是空的。另请参阅：趋势设置窗格9.4趋势显示窗格趋势显示窗格是窗口区域内的右下窗格。它实际上由两个显示器组成，其中一个显示器一次可见：•监视器显示器。•当前数据记录器的数据记录器显示。它们看起来和感觉非常相似，所以这里解释了它们的大部分特征。通过单击趋势设置窗格顶部的监视器或数据记录器选项卡，可以选择要查看的显示。所显示显示的选择也会影响趋势设置窗格。如果选择了监视器，则显示监视器设置；如果选择了数据记录器，则显示当前数据记录器设置。用户界面2-74 DriveWindow 2您可以使用趋势显示窗格查看监视器或当前数据记录器收集的趋势。趋势显示窗格包含以下内容：1.标题，指示当前显示的内容（监视器或数据记录器以及哪个数据记录器）2.X轴（时间轴）。它的长度可以由用户在趋势设置窗格中设置，也可以通过缩放来更改。如果收集的值多于显示的值，则可以水平滚动x轴。监控时，到达右端后，x轴实时滚动。3.Y轴。用户可以在趋势设置窗格中设置最小值和最大值，也可以通过缩放进行更改。最小值和最大值也可以通过垂直滚动进行更改。4.测量或记录的趋势。5.水平滚动条，仅当可以水平滚动x轴时才可见。6.垂直滚动按钮。可以向上和向下滚动y轴。7.X轴标签，始终为时间。水平滚动步长的大小取决于当前的x轴。如果通过单击箭头按钮水平滚动，滚动步长通常为x轴长度的五分之一。如果只显示几个值，则步长可以更小。如果通过单击滚动条的轴水平滚动，滚动步长通常等于x轴的长度。垂直滚动步长的大小等于y轴上两个刻度线的距离。显示的刻度线数量可能会根据当前y轴的最小值和最大值而变化。用户界面驱动窗口2 2-75如果未设置视图菜单中的放大切换（或标准工具栏中的放大图形按钮），则可以通过单击趋势显示窗格中的绘图区域（受轴限制的区域）来显示光标。
Removal can be done by Delete command, Cut command, or moving by drag and drop. Note that selections of the channel settings can also be used to remove logged items from the current datalogger. Also the triggering variable can be removed by selection. Removal can be done by Delete command, Cut command, or moving by drag and drop. Note! Many drives require that if not all channels are logged, the channels logged must be the first ones. DriveWindow takes care about this by shifting logged items and their scaling values “upwards”, if necessary. It also allows adding of a new logged item to the first free channel only. The trend display pane contains a short vertical scrollbar. Clicking the up or down arrow on it also changes Y Axis Maximum and Y Axis Minimum simultaneously. Y Axis Minimum and Y Axis Maximum also change simultaneously when y-axis is adapted. User Interface 2-72 DriveWindow 2 Note that if no valid datalogger is selected (for example, an open parameter file is selected in the browse tree pane), n/a is displayed in all other value fields except the channels, which have n/a in the setting names and the values (scaling) are empty. The datalogger display in the trend display pane is empty, too. User Interface DriveWindow 2 2-73 If the current datalogger is not properly initialized, many of the value fields display n/a, all channels have n/a in their setting names and the values (scaling) are empty. The datalogger display in the trend display pane is empty, too. See Also: Trend Settings Pane 9.4 Trend Display Pane The trend display pane is the lower right pane within the window area. It actually consists of two displays, one of which is visible at a time: • Monitor display. • Datalogger display of the current datalogger. They look and feel quite similar, so most of their features are explained here. You select the display you want to see by clicking the Monitor or Datalogger tab at top of the trend settings pane. Selection of the display shown also affects the trend settings pane. It shows the monitor settings, if monitor is selected, and the current datalogger settings, if datalogger is selected. User Interface 2-74 DriveWindow 2 You use the trend display pane to view trends collected by the monitor or the current datalogger. The trend display pane contains the following: 1. Title, which indicates, what is currently displayed (monitor or datalogger and which datalogger) 2. X-axis (the time axis). Its length can be set by user in the trend settings pane and also changed by zooming. You can scroll x-axis horizontally, if there are more values collected than are displayed. While monitoring, the x-axis scrolls in real time after the right end has been reached. 3. Y-axis. Minimum and maximum can be set by user in the trend settings pane and also changed by zooming. Minimum and maximum can also be changed by vertical scrolling. 4. The measured or logged trends. 5. Horizontal scroll bar, which is visible only when horizontal scrolling of the x-axis is possible. 6. Vertical scroll buttons. You can scroll the y-axis upwards and downwards. 7. X-axis label, always Time (s). Size of the horizontal scrolling step is dependent on the current x-axis. If you scroll horizontally by clicking the arrow buttons, scroll step is usually a fifth part of the length of the x-axis. If only a few values are displayed, the step can be smaller. If you scroll horizontally by clicking the shaft of the scroll bar, scroll step is usually equal to the length of the x-axis. Size of the vertical scrolling step is equal to the distance of two tick marks on the y-axis. Number of tick marks shown may vary depending on the current y-axis minimum and maximum. User Interface DriveWindow 2 2-75 If the Zoom In toggle in the View menu (or zoom in graph button in the standard toolbar) is not set, you can display a cursor by clicking the drawing area (area limited by the axes) in the trend display pane.
