Properties

It has the following properties:background: background colour of the graphic objectborderColor: colour of the border of the graphic areacursor: choose the cursor display mode.

• NONE: no cursor will be shown
• SINGLE: only one cursor displayed
• FULL: a cursor for every curve

index: allows to use the widget more than one time inside the program (e.g.: on two different pages). In this case the widgets must have a different, unique index (e.g.: “1” for the first widget, “2” for the second and so on). This value will be used to generate the cursor system variables.gridBackground: background colour of the graphic areagridX: horizontal space between the different axes of the grid inside the graphic area. The value is calculated with fixed limits 0-100, both for X axis and Y axis. With, for example, gridX = 10, the graphic area will be divided into 10 equal spaces, tracing 9 vertical lines.gridY: vertical space between the different axes of the grid inside the graphic area. The value is calculated with fixed limits 0-100, both for X axis and Y axis. With, for example, gridX = 10, the graphic area will be divided into 10 equal spaces, tracing 9 horizontal lines.gridColor: color of the grid inside the graphic area

• datalogs: list of the Datalogs to display as graphic curves. Note: while it is possible to specify more than 8 curves, this component allows to configure colour and enables the first 8 only.
• timeGap: time interval for initial display, expressed in seconds. It expresses the width of the window to display, also used as reference value when the central reset button of the X axis is pressed.

refreshTime: graph refresh time, in seconds.autoPan: if it is active, the graph will maintain the right limit fixed on the most recent value of the curves displayed. Deactivate the autoPan using the horizontal bar and the bottom of the graph. Press the central reset button to reactivate it.autoScale: if it is active, the graph will expand the vertical limits if necessary, to display all the values of the window. Deactivate the autoScale using the vertical bar on the left of the graph. Press the central reset button to reactivate it.average: when the zoom factor is very high and a sufficiently large time interval to require more samples than the graph capacity is requested (number of pixels horizontally), the system extracts a “subset” of non contiguous values, skipping values at regular intervals. With this property activated a fictitious value corresponding to the average of the values skipped will be added between 2 intermediate values actually displayed.

• formatDateID: allows to customise the date format shown at the bottom of the graph and cursors value, using a formatting string. Customisation takes place through a string with dynamic parameters. Default value (used with value “[none]”): %14/%15/%8 (example: 15/07/2010) The following parameters are available: %6 : is replaced by the indication of the day [1..31] %7 : is replaced by the indication of the month [1..12] %8 : is replaced by the indication of the year in four figures %9 : is replaced by the indication of the year in two figures %14: like %6 but with zero to the left if necessary %15: like %7 but with zero to the left if necessary %16: like %9 but with zero to the left if necessary
• formatTimeID: allows to customise the date format shown at the bottom of the graph, using a formatting string. Customisation takes place through a string with dynamic parameters. Default value (used with value “[none]”): %10:%12:%13 (example: 22:51:48) The following parameters are available: %1 : is replaced with the hour [0..23] %2 : is replaced with the hour [0.12] %3 : is replaced with AM or PM %4 : is replaced by the indication of the minutes [0..59] %5 : is replaced by the indication of the seconds [0..59] %10 : like %1 but with zero to the left if necessary %11: like %2 but with zero to the left if necessary %12: like %4 but with zero to the left if necessary %13: like %5 but with zero to the left if necessary
• antiAlias: allows to “round” the graphical “pixel” artefacts (steps) by applying an antialiasing method. For further information about antialiasing, please see chapter “Configuration parameters – Graphics options – Fixed text antialiasing method”.

8 identical sections follow, relating to a maximum of 8 Datalogs that can be displayed. The section of curve 1 is the following:s1_color: colour of the curves1_enable: label which allows to switch on/off the corresponding curve.
