Dewesoft X offers two different time base types for multiple graphs: single time axis or multiple time axes.
Tick the Single time axis checkbox to change between these two modes.
Single time axis
The advantage of the single time axis is to have more space to display the data.
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 axis type (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.
- Relative - elapsed time since recording or monitoring began
- Absolute - current date and time; this format is compatible with the timing information according to UTC
- Absolute (time only) - current time only
- Absolute (day+time) - day in year and current absolute time
To make the analysis more comfortable, Dewesoft X contains the possibility to change the number of grid lines in the recorder display.
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.
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 numbers of display types).
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 instrument. 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.
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, display will reduce the data continuously according to the static/reduced rate selected in 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.
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 limit 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 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.
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 same, except time axis is vertical.
Y-axis scaling/auto scaling
IMPORTANT: This way of changing 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 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.
- Auto scale 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 ow n ± value).
Right mouse button
Undo auto scale for the selected channel (see also above).
<CTRL> + Right mouse button
Selects all available channels for undo auto scale.
