Dewesoft X offers two different time base types for multiple graphs on the X-axis: single time axis or multiple time axes.
Image 47: Single time axis enabled
Single time axis
The advantage of the single time axis is to have more space to display the data.
Image 48: Single time axis
Multiple time axis
The advantage of the multiple time axes is to make it easier to read time-related information.

Time axis type
You can show either absolute or relative time in the Time display option (in case of the Vertical recorder in the vertical direction) for each graph. Click on any graph to select it and then use the selector to make your choice.
Image 50: Time display type
- Relative - elapsed time since recording or monitoring began
Image 51: Relative time
- Absolute - current date and time; this format is compatible with the timing information according to UTC
Image 52: Absolute time
- Absolute (time only) - current time only
Image 53: Absolute time only
- Absolute (day+time) - day in year and current absolute time

Grid resolution and Ticks type
To make the analysis more comfortable, Dewesoft X contains the possibility to change the number of grid lines in the recorder display. This can be done either in the X or Y direction. You can change this by switching the Ticks type option to Divisions or either Step. The only difference is that the Step tick type have also minor ticks, not only major ones as the Divisions tick type has.
Image 55: Edit grid resolution by defining the number of ticks
Depending on the range and signal, it may be more practical to change the number of grid lines in Y-axis ticks from 2 (default) to 8 - or remove them completely.
Image 56: Adjusting the grid resolution
Your acquired signal may not be only a static signal; if you have ever tried to display a high-dynamic signal with digital values, you know that you have to make some kind of statistic to get representative values. Therefore, all instruments offer different display types, which can be selected from the Display type drop-down list (Different setups will give you a different number of display types).
Image 57: Display type selection
IMPORTANT: Be aware that all these display types represent only statistic values for the online display. The settings have no influence on the other displays or the data storage.
With the Average time drop-down list, you can define the update rate for the selected widget. As a standard, the values for the display type will be calculated Fast (0.1 s) over a period of 0.1 seconds, which also represents the internal minimum calculation period.
Image 58: Update rate selection
The system will still run at the dynamic sample rate and Dewesoft X will acquire the data with full speed, calculate minimum, maximum, average and RMS for this time interval, however, every data point will NOT be displayed on instrument and stored, but only these calculated values. When From reduced rate mode is selected, the display will reduce the data continuously according to the static/reduced rate selected in the STATIC/REDUCED RATE drop-down list in the channel setup.
Upper & Lower limit
You can set high and/or low alarm limits for each instrument, which will cause the instrument numbers to change from green to red when it is either above the high limit or below the low limit (colors can be easily adjusted).
If you want to use limits for an instrument, select it by clicking on it once. Check the Use boxes to activate/deactivate high or low limit detection. If enabled, you can enter the alarm level for each.
Image 59: Defining upper and lower limit
For example, if we want to have the signal change to red when it rises above 330 deg or changes to yellow when it falls below 200 deg, we set this meter up accordingly (see picture above).
Note: the number changes to red as a standard when it is outside of both limits and remains green when it is within the limit(s).
You can set Lower limit, Upper limit, or both limits for each meter. If you want to change the limit color simply click on the colored field next to the high or low limit field and choose the desired color from the appearing color selector window.
Note: The upper and lower limit is only a visual effect, it is completely independent of the Alarm monitoring function.
Minimum and maximum shown value
You can define a Minimum and a Maximum shown value for the bar graph; this feature is very important for better scaling on the display. For example, your angle measurement range is from 0° to 360°C.
Just enter both values and the bar graph scaling will change immediately.

Run mode - Time axis scaling
IMPORTANT: This way of changing the Time axis can't be done in Design mode - it is available only in Run mode.
Use the blue plus and minus symbols to expand or compress the time axis.
Image 61: Time axis scaling in run mode
Clicking minus will show more time across the graph. You can show the entire length of the recording, regardless of how long it is! Even days and days of data can be shown here.
By unchecked Single time axis - the multiple times axis, this control appears for each graph. Appearance and functionality by vertical instruments are the same, except the time axis is vertical.
IMPORTANT: This way of changing the Y-axis can't be done in Design mode - available only in Run mode.
If you want to change the Y-axis for any input, the recorder offers two possibilities:
- Enter values
Image 62: Manually entering scaling values You may enter the values by yourself - simply click on the number at both extremes and then type in a new number. This is possible when the cursor has the following appearance: A grey outlined box around the scale value indicates the selected channel.
Image 63: Auto-scaling option enabled Move cursor to the axis scale. If you have reached the auto scale area, the cursor changes to the following appearance: A gray outlined box around the scale value indicates the selected channel. Press the left mouse button to activate auto-scaling for this channel or press the right mouse button to undo auto-scaling. The auto-scaling function always calculates the minimum and maximum value of the currently displayed signal and uses these values for scaling. The scaling will be only updated when you press the left mouse button!
Additional auto-scale functions
Dewesoft X offers additional auto-scale functions when you press keys together with the left or right mouse button (it only works in the area left of the graph, where the scale is):
Left mouse button
Auto scales the selected channel (see also above).
<CTRL> + Left mouse button
Selects all available channels and scales all channels to the same maximum and minimum (highest and low estimated value within all channels).
<CTRL> + <ALT> + Left mouse button
Selects all available channels and scales each channel to its own maximum and minimum.
<SHIFT> + Left mouse button
Scales the selected channel symmetrical around zero (± values are the same).
<CTRL> + <SHIFT> + Left mouse button
Scales all available channels symmetrical around zero (all ± values are the same)
<CTRL> + <SHIFT>+ <ALT> + Left mouse button
Selects all available channels and scales each channel symmetrical around zero (each channel to its own ± value).
Right mouse button
Undo auto scale for the selected channel (see also above).
<CTRL> + Right mouse button
Selects all available channels for the undo auto-scale.
