PETL101AER系统备件
请注意，光标也会被打印（如果可见）。根据显示的是缩放值还是未缩放值，光标是带有以下数值的虚线（缩放值）或虚线（未缩放值）垂直线：1.光标点的时间（垂直写入）。2.对于每个趋势，光标点的值和括号内的通道编号（如果有多个趋势）。可以通过“视图”菜单中的“图形光标”命令或“文件”菜单的“图形”子菜单中的图形首选项命令来选择是否显示缩放值或未缩放值。如果将光标设置在趋势彼此接近的点上，则数值可能重叠，并且不可读。在这种情况下，尤其是要打印图形时，可以通过在“视图”菜单中的“图形光标”命令显示的“图形游标”对话框中取消选中某些值来隐藏这些值。可以通过拖动或单击趋势绘图区域中的另一点来水平移动光标。您可以通过单击绘图区域（轴外的区域）外的趋势显示窗格来隐藏它，或者通过切换“视图”菜单中的“放大”（或标准工具栏中的放大图形按钮）来更改为放大模式。用户界面2-76 DriveWindow 2如果设置了“视图”菜单中的“放大”切换（或标准工具栏中的放大图形按钮），则可以通过在趋势显示窗格中拖动鼠标进行放大，以便在拖动时显示的矩形中至少有一部分位于趋势绘图区域（受轴限制的区域）内。注意，当显示矩形时，DriveWindow保持在屏幕的顶部。此时，只有使用相同功能的应用程序（如Windows任务管理器）才能覆盖DriveWindow。如果这样的应用程序覆盖了矩形，则无法确定缩放操作的行为。矩形区域用于在新的缩放级别中近似确定新的x轴长度和y轴最小值和最大值。新值通过舍入为“平滑”值从矩形生成。新值也显示在趋势设置窗格中。注意，x轴长度和y轴最小值和最大值的舍入值可能与缩放前相同。如果是这种情况，您可以使用趋势设置来更改它们。要恢复到以前的缩放级别，请选择“视图”菜单中的“缩小”（或标准工具栏中的缩小图形按钮）。要将缩放重置为未缩放级别，请在“视图”菜单中选择“缩放重置”（或在标准工具栏中重置图形缩放按钮）。用户界面驱动窗口2 2-77另请参阅：窗口区域9.4.1监视器显示监视器显示是趋势显示窗格中显示的显示之一。您可以通过单击趋势设置窗格顶部的监视器选项卡来选择显示。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。监视器可以处于以下状态：•已清除。您可以在此状态下更改任何设置。只能清除已停止的监视器。无法导出图形（没有要导出的值）。无法显示光标。无法缩放和水平滚动。•跑步这些趋势是实时绘制的。无法显示光标。无法缩放和水平滚动。无法保存、打印、复制和导出图形。•已暂停。与“已停止”相同，但仍会收集值，但不会绘制，以后可以继续监视。恢复运行状态时，将绘制收集的值。您还可以停止监视器，在这种情况下，在场景后面收集的值将丢失。•停止。只能更改历史缓冲区的模式、间隔和大小。可以显示光标。可以缩放和水平滚动。在再次运行监视器之前，必须清除它。请注意，某些更改（如缩放）需要重新绘制历史缓冲区中的所有数据，这可能需要很长时间。您可以在所有状态下垂直滚动并更改x轴长度和y轴最小值和最大值。
Note that the cursor is also printed, if visible. Depending on, whether scaled or unscaled values are to be shown, the cursor is either a dotted (scaled values) or dashed (unscaled values) vertical line with the following numerical values: 1. Time at the point of the cursor (written vertically). 2. For each trend, value at the point of cursor, and the channel number within brackets (if there is more than one trend). The selection, whether to show scaled or unscaled values, can be made either by the Graph Cursor command in the View menu, or Graph Preferences command in the Graph submenu of the File menu. If you have set the cursor at a point, where the trends are near each other, the numerical values can overlap, and are not readable. In such cases, especially if you are going to print the graph, you can hide some of the values by unchecking them in the Graph Cursor dialog box shown by the Graph Cursor command in the View menu. You can move the cursor horizontally by dragging, or by clicking another point within the trend drawing area. You can hide it by clicking the trend display pane outside the drawing area (area outside the axes), or by changing to zoom in mode by toggling Zoom In in the View menu (or zoom in graph button in the standard toolbar). User Interface 2-76 DriveWindow 2 If the Zoom In toggle in the View menu (or zoom in graph button in the standard toolbar) is set, you can zoom in by dragging the mouse in the trend display pane, so that at least some of the rectangle shown while dragging is inside the trend drawing area (area limited by the axes). Note that while the rectangle is shown, DriveWindow stays topmost on the screen. Only an application using the same feature (like Windows Task Manager) can overlay DriveWindow at that time. If it happens that such an application overlays the rectangle, behavior of the zoom operation can not be determined. The rectangular area is used to approximately determine new x-axis length and y-axis minimum and maximum in a new zooming level. The new values are made from the rectangle by rounding to a “smooth” value. The new values are also show in the trend settings pane. Note that it is possible that the rounded values of x-axis length and y-axis minimum and maximum are the same as before zooming. If that is the case, you can use the trend settings to change them. To restore back to the previous zooming level, select Zoom Out in the View menu (or zoom out graph button in the standard toolbar). To reset zooming back to the unzoomed level, select Zoom Reset in the View menu (or reset graph zoom button in the standard toolbar). User Interface DriveWindow 2 2-77 See Also: Window Area 9.4.1 Monitor Display The monitor display is one of the displays shown in the trend display pane. You select the display by clicking the Monitor 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. The monitor can be in the following states: • Cleared. You can change any of the settings in this state. Only a stopped monitor can be cleared. Exporting the graph is not possible (there are no values to export). No cursor can be shown. Zooming and horizontal scrolling are not possible. • Running. The trends are drawn in real time. No cursor can be shown. Zooming and horizontal scrolling are not possible. Saving, printing, copying, and exporting the graph is not possible. • Paused. Same as Stopped, but values are still collected, however not drawn, and you can later continue monitoring. Collected values are drawn, when you restore running state. You can also stop the monitor, in which case the values collected behind the scene are lost. • Stopped. Only mode, interval, and size of history buffer cannot be changed. Cursor can be shown. Zooming and horizontal scrolling are possible. You have to clear the monitor before running it again. Note that some changes (such as scaling) require redrawing all data in the history buffer, which can take a long time. You can scroll vertically and change x-axis length and y-axis minimum and maximum in all states.
