On the Data tab, you can select the lines that should be displayed in the chart. The selection is only available for charts of the Regular type.
Select the lines you want to see in the report. You can select no more than 6 variables. 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.
To change the line name, click on it with the left mouse button and edit the text. To reset the original name, click on the Default icon (). The icon is inactive if the name has not been changed.
In addition, it is possible to change the order of the items. To do this, drag the iconlocated to the left of the required line up or down.
In addition to selecting columns, the settings are available on the same-name tab.
The tab is divided into two sections:
In the Parameters section, it is possible to activate the Split sensors and Count from zero.
If a unit has several sensors of the same type and you need to create a chart for this type, then by default the lines of such sensors are displayed in the same chart. Check the Split sensors option to create an individual chart for each sensor. For example, for a unit with two voltage sensors, external and internal, a chart with two lines (the option is not checked) can be built, as well as two charts with one line (if the option is checked).
If for the data points selected for a chart there are several sensors, the upper one is split. Let us assume that a unit has two voltage sensors and two temperature sensors, and you are building a voltage/temperature chart for it. If the Split sensors option is off, you will get one chart with four lines in it. If the Split sensors option is on, you will get two charts with three lines on each: one chart will contain the first voltage sensor and both temperature sensors, and another one will contain the second voltage sensor and both temperature sensors.
Count from zero
The Count from zero option is responsible for scaling the chart. By default, the range of the Y scale depends on the range of values falling within the specified interval. That is, if, for example, the temperature fluctuates from 3 to 5 degrees, then the reading on the Y scale starts at 3, and the line, in this case, occupies the maximum space on the chart. If the Count from zero option is activated, the Y-axis on the graph is always built from zero to the largest value (if the values are negative, then from the lowest value to zero).
The image below shows an example of two voltage charts for the same unit within the same time interval. The first chart is regular, the second — with the Count from zero option turned on.
The following settings are available in the Filter section:
- Sensor masks;
- Line colour.
This option allows you to specify the sensors on the basis of which the chart should be built. The option does not influence the Speed, Altitude, Fuel consumption by math charts, as they can be built regardless of whether a unit has sensors or not.
Specify the mask of the required sensor. To do it, enter its full name or part of the name. You can use special characters: * (replaces any number of characters) or ? (replaces one character). The name of the sensor cannot contain commas.
If the masks are not specified, the sensors of the required for building the chart type are determined automatically.
This setting allows you to select the markers that should be displayed in the chart. The same markers as on the map can be displayed here, except for the markers of initial and final positions and the markers of violations.
The setting of graphical elements filtration influences the display of markers and backgrounds.
The intervals of such events as stops, parkings, trips, connection losses, and work of engine hours can be used as a chart background. Using these backgrounds you can correlate a chart value and an interval to which it corresponds. Different colours can be assigned for the event intervals. To select a colour, click on the colour box, choose the colour from the palette and click OK.
The background of the event intervals is opaque and has a display priority, that is, the interval above is overlapped by the lower ones. To change the priority, drag the desired interval of events up or down using the double arrow iconto the left of the name of the desired interval.
This section allows you to use the sensor's colour scheme to display the line of a corresponding chart. To apply the sensor's color scheme, indicate its mask in the field opposite the line name (the fields correspond to the items selected on the Data tab). If no mask is indicated, the default colours are used.
