In the parameters block (right part of the dialog) you can indicate particular sensors on the basis of which the corresponding charts will be built. This selection does not affect such charts as 'Speed', 'Altitude', 'Fuel consumption by math' because these charts can be built regardless to unit sensors availability.

To indicate the necessary sensors, enter the corresponding masks. You can indicate full sensor name or its part using wildcard symbols like asterisk * (replaces any number of characters) or question sign ? (replaces one character). A sensor name cannot contain comma. If no masks are indicated, then the system automatically defines sensors of a required type to build charts.

In this section you can choose markers to visualize corresponding events on a chart. The same markers are used on the map.

 Note that graphical elements filtration applied affects displaying of the corresponding markers and backgrounds of a chart.

The following intervals of events can be used as a chart background: stops, parkings, trips, connection losses, and work of engine hours. Using these backgrounds you can correlate a chart value and an interval to which it corresponds. Different colors can be chosen for a background (click the color box).  Note that backgrounds are opaque and they have a priority of visualization. In other words, an upper interval covers the bottom ones. To change a priority, drag and drop a corresponding event interval.

This section provides a possibility of using sensor's color scheme as a line color of a corresponding chart. To apply sensor's color scheme, indicate its mask in the corresponding field of the section. If no mask is indicated, then default colors are used.

If there are several sensors of the same type and a chart of the same type is created, the curves for all sensors will appear in one chart. To split them, choose the appropriate option 'Split sensors'. Then an individual chart will be built for each sensor. For example, there is a unit with two voltage sensors — external voltage and internal voltage. If creating a voltage chart for this unit, we can get one chart with two curves on it or two chart with one curve on each (if 'Split sensors' option is enabled).

If several data is selected for the chart and for each several sensors exist, 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 'Split sensors' option is off, you will get one chart with four curves in it. If '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 again two temperature sensors.

This flag is responsible for chart zoom. By default, Y scale range depends on the range of values found within the interval. For instance, if the temperature varies from 3 to 5, Y axis begins from 3, and the curve occupies maximum space in the chart. If the option 'Count from zero' is activated, Y axis is built from zero to the highest value (or from the lowest value to zero if the values are negative).

On the picture below you can see two temperature charts built for one unit for the same time interval. The first chart is regular, the second one has the flag 'Count from zero' activated.

Almost all regular charts can be presented in two forms: raw and smoothed. Raw charts are drawn from one message to another in a linear way and have angular look. Smoothed charts look more streamlined. The smoothing algorithm is the same for all chart kinds.

Below is an example where the orange line displays a raw speed chart, and the blue line displays a smoothed speed chart.
