14. Graph Pane¶
Graph Pane contains Matrix with recent measurements, Static Trend Graph, Time Domain and Frequency Domain, all of them essential tools for signal understanding and signal development monitoring. All available tools are powerful help in delivering actionable conclusions and still easy and practical in daily use. Here are the details about them.
14.1. Matrix¶
Matrix shows four most recent readings, all four indicators (RMS, maxRMS, Peak and Crest Factor) for Ultrasound and Vibration and additionally, Added Grease quantity for LUBEsense1 sensor (LUBExpert and SDT 270 with LUBExpert features).
Reading data is sorted from most recent to oldest, top to bottom.
Each Ultrasound and Vibration indicator is being displayed in color corresponding with alarm status, as in picture below:
❶ Alarm assigned and in Warning status
❷ Alarm assigned and in Danger status
❸ Alarm NOT assigned
❹ Alarm assigned and NOT triggered
❺ Alarm assigned and in Alert status
By right clicking on indicator, you hide or show it in Static Trend Graph, focusing on indicator most important for the purpose of analysis.
14.2. Static Trend Graph¶
Static trend graph plots reading values in respect to time they were collected. It can be understood as a plot describing behavior in time. Values being table, trending down or trending up, are essential information for understanding asset health. Static Trend Graph contains lots of information and can be easily customized. Here is an example of static Trend Graph, so we can explain all details:
❶ Click to enlarge
❷ Events
❸ Events
❹ Y axis - amplitude for each displayed indicator, (auto scaled or Ymax defined)
❺ Trend line for each indicator
❻ Data points
❼ Alarm level
❽ X axis - time
❶ Font color of indicator on Y axis
❷ Corresponds with trend line of that indicator
You can customize your Graphs.
14.2.1. Define reading data to display¶
Left click on Options and then Graph & Static Trend settings in top toolbar, as shown in picture below:

❸ Select color scheme
❹ Apply selected settings
❺ Save settings and close the menu
14.2.4. Define preferred settings for image export (Graph export)¶
This menu allows you to save your preferred setting for image export. Once you select exporting image, those settings will be offered as default, but you can still change them in export menu
14.2.5. Zoom¶
Place mouse pointer in graph and scroll mouse wheel to zoom in and zoom out. Zoom bar at the bottom of the graph shows you where the part of the graph you are looking at is positioned in entire graph. Hold non shaded part and move it left and right to dee other parts of the graph.
Another way to zoom in is to hold left click on your mouse and drag to form a rectangle. Selected area will be displayed. To zoom out, use mouse wheel.
To undo zoom and go back to original full view, right click within the graph area, and choose Undo Zoom function, as below:
14.2.6. Show/Hide Labels¶
Labels, containing date, time, and value for each datapoint can be shown or hidden. Right click anywhere within graph area and select Include Data Labels.
14.2.7. Maximize¶
Right click anywhere in the graph area and select Maximize; graph will be displayed full screen. To exit full screen, press esc or click in top left corner of the graph.
14.2.8. Export graph¶
Right click anywhere in the graph area and select Export Dialog; Export Control window will pop up.
Choose your settings and export graph.
14.2.9. Overlay Graph¶
Right click anywhere in the graph area and select Overlay; Overlay Graph window will pop up.
Choose the measurement point you want to overlay with current graph, choose indicators to show and confirm settings. To cancel overlay, follow the same path and uncheck selected overlay measurement points.
14.2.10. Accessing settings menu directly from graph¶
Left double click within the graph, and you will access settings menu directly. When settings assessed directly from the graph, it is locked to that graph type. That means that change is possible for that type only. Same shortcut is available for following graph types: Time Domain, Frequency Domain, Static Trend and Initial-Base line in case of Lubrication.
14.3. Time Domain Graph¶
Time Wave Form is fundamental way of representing an event collected through Dynamic measurement. It plots amplitude in time, thus giving us a clear view on what happened and when.
Select the measurement you want to see and click on enlarge.
❶ Click to enlarge
❷ Select measurement
Time Domain window will be enlarged, and all Time Domain tools will be displayed and active:
❶ Play and stop audio
❷ Export signal/export audio
❸ Frequency domain

14.3.7. Delete Portion of the Signal¶
This function enables you to temporarily delete potion of the signal (by delete, meaning is that selected portion is set to amplitude zero), for the purpose of analysis. Indicators will automatically be recalculated based on new TWF values. Zoom on portion of the signal you want to delete and press on indicated tool. Note, deleted portion of the signal will be exactly that on the screen. By selecting any other measurement and coming back to the processed signal, delete action will be reverted.
