Plot

Open data as spreadsheet

All plots and most tables have an Open spreadsheet button. It lets you export the current table or the data of the current plot to a csv-file (comma-separated value), which is automatically or easily opened with any spreadsheet application, like Microsoft Excel.

Alert zones

When a plot contains alert zones, a ! button will appear. Pressing that exclamation mark will automatically scale the plot, so all alert zones are in view.

Hiding series

By clicking on a legend entry, the corresponding series will be plotted alone. Add more series by clicking more entries. Click any colored entry again, to display all series.

Plot menu

Left click or tap any value point to open the plot menu. To close it, click outside the menu or press the escape key. Dependent on the context, the plot menu may contain these actions:

• ! Median time

  • Plot time has been aggregated at this zoom level and some fine-grained actions are not available.

• Plot versus time

• Plot versus [axis]

• (Un)pin profile

• Download file(s)

  • Only when imported from an original data file, for the moment.

  • For convenience, this will also download the file of the instrument datum, if any.

• Set instrument datum

• Clear instrument datum

• Mark as invalid

• Delete

• Delete series

  • This includes invalid values.

  • This will only delete values. The sensor and its metadata will not be touched. This way, you still can exclude the sensor from importing, if needed.

• Delete file

  • This includes invalid values.

  • In addition to values, the file itself will be deleted.

Some actions can be applied on time ranges, using the following menu options:

• Select from here

• Zoom up to here

• Invalid up to here

• Delete up to here

• Cancel selection

Vertical measurements

By default, Vision 42 will plot a profile in the conventional way; with the x-axis pointing right and the y-axis pointing up. Vertical measurements will be plotted vertically, with an optional ground level indication. The orientations of the x-axis and the multiple y-axes will be set automatically, based on the metadata information received. Here are some examples, with the name of the vertical axis mentioned between brackets:

• Measurand SAA (Z)

• Geokon in-place inclinometer (z)

• RST Instruments in-place inclinometer (z)

• RST Instruments inclinometer (Depth)

• Glötzl inclinometer (Step)

Vision 42 was designed to function fully automatically and in real time. Usually, the loggers or instruments send their data directly to us, or the app will fetch them from somewhere. Next the cumulative profiles ​​of the above inclinometers will be calculated, for example. Plotting of values relative to a dynamic instrument datum is embedded in the application, as well is recalculation to absolute levels in mASL.

Inclinometer checksums will not be plotted by default, nor will their depths show up. This behavior can be controlled by the do-not-plot flag.

In-place inclinometers

For the sake of traceability, Vision 42 will make use of the original vertex numbers in the IPI file. The (excluded) angles and the temperatures are being measured on those vertices. As is the case for inclinometers, the top angle measurement will have a relative depth of zero. This way, the relative depths will correspond to the depth values in the data files, if any.

The calculated cumulative profile contains an extra value, the zero origin. It begins half a gauge deeper and ends half a gauge higher, while the intermediate vertices fall between the angles. These interlaced vertices will be numbered higher, following the original vertices.

Invalid measurements

Invalid measurements:

• can be marked using a graphical selection of the beginning and the end.

• will not be plotted.

• are excluded from tables with manual water level measurements.

• will not be forwarded.

• will not be sent through the REST API.

• will not be used to calculate formulas.

• will not be used when compensating with air pressure.

Marking measurements as invalid has the advantage over deleting, in that they do not return when one reimports data. Invalid measurements will only become deleted using Delete file or Delete series in the plot menu.

For profile data, marking a value of the first vertex (Z1, Depth1, ...) as invalid will exclude that time point from the slider.

Measurement interval

The measurement interval is defined within Vision 42 as the time between the last two measurements. This allows dynamic measurement frequencies.
