Chart Types
  • charts

The charts available in reports can be divided into regular and special ones.

Regular charts

The charts of this type differ in that the X-axis always lays time, and the data for the Y-axis is selected from the list on the Data tab:

  • Speed (km/h or mph);
  • Altitude (meters or feet);
  • Engine operation (on/off);
  • Engine efficiency sensor;
  • Voltage (volts);
  • Temperature (degrees Celsius);
  • Engine revs (rpm);
  • Cargo weight;
  • Counter sensor;
  • Custom sensors;
  • Custom digital sensors (on/off);
  • Absolute mileage;
  • Mileage in trips;
  • Instant mileage;
  • Fuel level (liters or gallons);
  • Processed fuel level (liters or gallons);
  • Fuel consumption by ImpFCS;
  • Fuel consumption by AbsFCS;
  • Fuel consumption by InsFCS;
  • Fuel consumption by FLS;
  • Fuel consumption by math;
  • Fuel consumption by rates.

You can select no more than 6 variables for a chart. However, several lines can correspond to one variable, for example, Speed and Speed (smoothed). Therefore, the resulting number of the selected lines may be more than 6.

The picture below shows the speed chart combined with the fuel level chart. To receive such a chart, it is required to set the chart type as Regular and select the Speed,Speed (smoothed) and Fuel level data.

Each curve on a chart is assigned its own colour. On the left, in the Report result block, you can specify which colour corresponds to which curve. Their names are taken from the report template. In addition to the name for the curves, the units of measurement are also indicated.

The names of the lines of the chart can be changed in its properties in the report template. However, if the line is displayed on the basis of sensor readings, then it is given the name of the sensor. The sensors the readings of which should be displayed in the chart are selected in its settings.

Click on the curve name in the Report result section to enable/disable its display on the chart.

Smoothing

Almost all regular charts have two forms: a raw form and a smoothed one (the word smoothed is indicated in brackets after the name). Smoothing affects the style of displaying the lines. Raw data charts are built strictly from message to message, and, as a result, have angular outlines. Smoothed charts have smoother outlines because they use a smoothing algorithm. It is the same for all charts and is not customizable.

Below is an example of a chart in which a blue line shows a raw speed chart, and a red one shows a smoothed speed chart.

Regular fuel level charts

Two fuel level charts are available among the charts of the Regular type.

Chart

Description

Fuel level

Shows data taking the temperature coefficient into account without applying smoothing.

Processed fuel level

If filtration is configured in the properties of the selected sensor, smoothed data is shown. The smoothing depends on the filtration settings. The temperature coefficient is also taken into account in this chart.

Unlike special fuel level charts, the regular charts show data only in the litre-to-time ratio. However, you can select other data, such as voltage, so that it is displayed on the chart with the fuel level. 

Regular mileage charts

Four kinds of mileage charts can be created: absolute mileage, mileage in trips, instant mileage, and instant mileage smoothed. The first two show how mileage changed (increased) over time. Absolute mileage chart is built on the basis of all messages, which means that any inaccuracy and outlying data affect the resulting chart. Mileage in trips chart displays the data taking trip detector settings into account. Below you see the chart with curves for absolute mileage (blue) and mileage in trips (red).

The Instant mileage chart represents the data in the mileage from the previous message to the current one form, that is the difference in the distance between two adjacent messages. This kind of chart can be useful to detect excessive mileage during connection loss, or to detect made-up additions to the mileage in cases where it is determined by special sensors (see the settings of the mileage counter in the unit properties). Instant mileage can be smoothed.

Special charts

Along with the regular charts, the following special charts are available:

  • Processed fuel level (consumption);
  • Processed fuel level (fillings);
  • Processed fuel level (drains);
  • Speed/Fuel consumption by AbsFCS;
  • Speed/Fuel consumption by FLS;
  • Speed/Fuel consumption by ImpFCS;
  • Speed/Fuel consumption by InsFCS;
  • Speed/Fuel consumption by math;
  • Speed/Fuel consumption by rates.

Settings for these charts are fixed and cannot be changed. Editing is available only for the name of the chart. Also, it is possible to select the required sensors (indicate the mask of the sensor) or split sensors.

Processed fuel level

The special Processed fuel level chart shows the values which are used while calculating fuel level, fillings and drains in tables.

The chart shows the dependence of fuel level on mileage (litres/mileage). It can also show the dependence of the fuel level on time (litres/time) if the Calculate fuel consumption by time option is turned on in the sensor settings. In both cases, the chart is processed taking into account the filtration which is also set in the sensor settings.

The special Processed fuel level chart should be distinguished from two similar regular charts.

Below is the special Processed fuel level (consumption) chart. The Calculate fuel consumption by time option is enabled, median filtration is configured, the filtration level is 3.

Speed/Fuel consumption chart

This chart shows the dependence of average fuel consumption on speed. The data for it is taken from fuel consumption sensors of different types (such as impulse, absolute, instant) or fuel level sensor, or predefined consumption by math or rates. The calculation methods must be specified in the properties of the required sensors.
