On the Data tab, you can select the curves that should be displayed in the chart. The selection is only available for charts of the Regular type.

Mark the curves you want to see in the report. Two points can be checked simultaneously. In this case, two curves are displayed, for instance, speed and engine revs. There can be more curves, but only if there are no more than two variables in the chart, besides time.

To change the name of the point, click on it with the left mouse button and edit the text. To return the original name, click the Default button  (the button 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 double arrow icon , located to the left of the required curve, up or down.

In addition to selecting columns, the settings are available on the same-name tab.

The tab is divided into two sections:

• Parameters;
  
• Filter.
  

In the Parameters section it is possible to activate the Split sensors and Count from zero.

Split sensors

If a unit has several sensors of the same type and you need to create a chart by this type, then by default the curves 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 curves (the option is not checked) can be built, as well as two charts with one curve (if the option is checked).

If for the data points selected for a chart there are several sensors, the upper one will be 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 curves in it. If the Split sensors option is on, you will get two charts with three curves 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 curve 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;
  
• Markers;
  
• Background;
  
• Line color.
  

Sensor masks

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.

Markers

This option allows to specify the event markers, which should be displayed in the chart. Here, the same markers are used as for the events on the map.

 The setting of graphical elements filtration influence the display of markers and backgrounds.

Background 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 colors can be assigned for the event intervals. To select a color, click on the color box, choose the color 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 icon  to the left of the name of the desired interval.

Line color

This section allows to use the sensor's color scheme to display the line of a corresponding chart. To apply the sensor's color scheme, indicate its mask in the field opposite the curve name (the fields correspond to the items selected in the Data tab). If no mask is indicated, the default colors are used.
