YT chart properties
Here you can enter all the settings relating to a YT chart.
Behaviour
Auto Start | If this option is enabled, the chart starts the live display when a new recording is started. |
Data Tool Tip | If this option is enabled, a click on a data point results in display of a tool tip with the exact values of the data point on the X- and Y-axis, plus the timestamp and name of the corresponding channel. |
Default Display Width | This time specifies the standard width of the associated chart. This value is set, for example, when the rescale button is selected in the chart toolbar. |
Invert X-Axis | Switches the signal sequence from the default (left to right) to right to left |
Master Chart | In the drop-down list that is available here, a chart that is part of the current configuration can be selected and designated as master chart. All actions that are executed in the master chart are also automatically executed in this chart. A separate stop display option is provided, through which Y-zoom and Y-panning modes are available. An overview chart can also be displayed. |
Time Bar | Specifies whether the time bar is displayed in the chart. |
Tool Bar | Specifies whether the toolbar is displayed in the chart. |
Color
The background and frame color can be set by means of color dialogs.
Common
Comment | A free comment can be saved here. |
CPU Core | Here you can set (for each chart individually) which CPU core should be used for the current chart display. If required, multiple CPU cores can be specified for a chart. This may improve the performance. |
Show Name | Specifies whether the name of the chart is shown in the graph. |
X-Axis Grid
Use X-Axis Grid | The X-subdivisions in the chart can be switched on or off here. |
Use X-Axis SubGrid | Auxiliary lines for the finer X-subdivision of the main grid can be shown or hidden here. |
X-Grid Color | Color of the grid |
X-Grid Line Width | Line width of the grid in pixels |
X-SubGrid Divisions | Number of areas into which the main grid is subdivided by auxiliary lines. |
X-Axis Style
Since the X-axis is permanently assigned to a chart, all associated settings can be made here.
Ticks | Number of subdivisions |
X-Axis Color | Color of the X axis |
X-Axis LineWidth | Line width of the axis in pixels |
Y-Settings
Scale on Zoom | If this option is selected, the chart instructs all axes (X and Y) to perform an auto-scaling after a zoom or panning action. This can be used to expand the selected area. |
Stacked Y-axes | This setting can be used to specify whether the axes of a chart should be displayed side by side, so that the values of the attached channels are shown within the same area, or whether the axes should be above each other, each with its own representation range. |
Y-Zoom | Here you can set the chart behavior during zooming. If the option is set, you can navigate in the data of a chart in the Y-direction as well. This includes both zooming and panning (shifting the display with the mouse). |
To change the settings for several charts at the same time, please refer to the chapter Multiple selection.
The chart display is operated with the toolbar. The overview shows all buttons and their explanation (from left):
Play | Starts the live display mode. The data currently being accumulated are displayed. |
Break | The display switches to the pause mode. You can now navigate in the data already recorded without stopping the recording. |
Display-Width | The current display width is displayed here. It can be edited in the format hh:mm:ss,fff. The zoom function works down to the µs range. Alternatively, the display width can be changed by turning the mouse wheel in the selected chart window. The changed value is adopted automatically. |
Scroll buttons | The outer scroll buttons move the current display in steps that correspond to the display width. The inner scroll keys move the display only by a tenth of the display width and can be kept pressed to view the data set. |
Position | Shows the position. It can be edited in the format hh:mm:ss,fff. The colons are used as separators. If not all units are edited the format is sorted in ascending order, starting with seconds. |
Undo/Redo Time/Position | This option can be used to undo step changes in the display width or the current position, irrespective of how they were made (e.g. zoom, scroll, etc.). The right mouse button is likewise assigned this function. Once undone, values can be repeated with redo. |
Panning Horizontal | In the horizontal panning mode the current display can be shifted along the X-axis by clicking and dragging with the mouse. |
Panning Free | In the free panning mode the current display can be shifted along the X- and Y-axes by clicking and dragging with the mouse. |
Zoom Horizontal | A new time range for the display can be selected by stretching a rectangle over the X-axis. |
Zoom Free | You can zoom into the current display by stretching a rectangle over the graphic area. |
Zoom to Default | Carries out an autoscale on all axes. The X-axis is/axes are set to the default display time. |
Zoom Out Max | Scales the X-axis in such a way that all current values in the recording appear in the display. |
Overview | Use the Overview option to display a chart within the chart. The signal range currently shown in the main chart is highlighted in the Overview Chart. The Overview Chart also offers an absolute time axis for the whole recording time. |
Chart Snipping Tool | Screenshots of a chart can be edited and sent using the tool, see Chart Snipping Tool. |
By turning the mouse wheel you can also zoom in or out on the current display. The cursor position of the mouse determines the center.
The current recording times are displayed in the chart toolbar:
Start-Time | The common starting point of the recordings of all connected channels. The start time defines the zero point of the recording. |
End-Time | Maximum common time of all connected channels. The end time thus marks the final value of the recording. The difference between the end time and start time is maximally as large as the record time set (see Scope nodes). |
Position | The position time represents the zero point of the current chart, i.e. the time from the start time to the beginning of the display. |
Time | Absolute time at the chart origin |
Date | Absolute date at the chart origin |
