Working with Charts

Working with a chart consists in

  • interacting with its legend;
  • viewing information about points and going to messages;
  • using the tools.

Chart legend

The chart legend is displayed in the work area. Depending on the chart settings, the legend may contain three sections: markers, backgrounds, lines. 

Markers

This section displays the markers selected in the chart settings. The tooltip of each marker shows the type of events it denotes. If several fuel level sensors are configured for a unit, the fuel filling and theft markers corresponding to each of them have a numeric indicator

Click on a marker in the legend to hide or show it in the chart. The tooltips of the markers in the chart show information about the marked events.

The chart markers are displayed according to the settings of filtering graphical elements

Backgrounds

This section contains the backgrounds selected in the chart settings. All the selected backgrounds are displayed on the chart by default. To remove a background from the chart, disable it in the legend. For disabling or enabling all the backgrounds, use the All backgrounds checkbox. To see only one background and remove the others, point to it in the legend and click Only this.

The chart backgrounds are displayed according to the settings of filtering graphical elements. 

Lines

This section contains the lines of the data selected in the chart properties. If no sensors are specified in the chart settings in order to apply their colour intervals to the lines, the line colours are selected randomly each time you run the report.

The lines of all the selected data are displayed in the chart by default. To remove a line from the chart, disable it in the legend. For disabling or enabling all the lines, use the All lines checkbox. To see only one line and remove the others, point to it in the legend and click Only this.

The lines of the chart can be dashed on the segments where the interval between messages is greater than the value specified in the Maximum interval between messages parameter.

Viewing point info and going to messages

When pointing to any place of the chart, you can see a tooltip with basic information about this point: the date, time, and the parameter values received at that moment (or the moment near to that). The tooltip shows the values of all the lines selected in the legend. 

When you point to a certain line in the chart, the rest of the lines become lighter, and the name and value of this line is shown in bold in the tooltip.

When clicking on a point in the chart, you can see the icon  which allows you to go to the table with data messages. In this table, the message corresponding to the point is shown in a grey row. To hide the icon , click on it with the right mouse button or press Esc.

If the Messages service is enabled for the account, then when you click on a point in the chart, the place corresponding to it is indicated with a marker on the map.

To analyze points in the chart, you can also use the Show detailed information about points tool.

Toolbar

The toolbar above the chart contains the following tools:
