==== Explanation of the definition Keywords ==== | |||
#EQUATIONS: Starts an equations block. Such block only defines (partial) equations, it does not cause code generation in itself | |||
#CHART: Starts a chart definition | |||
#TITLE: Starts the title. All words until the next keyword comprise the title of the chart | |||
#CONNECTSTO: The integer numbers which follow CONNECTSTO represent a pane in the realtime [[Dashboard|dashboard]]. When clicked on that pane this chart appears. This is only valid on charts in the default output. For other outputs there is no semantics for CONNECTSTO and a warning is issued in the logfile if it is specified in any second or higher output. | |||
#PLOT: Starts the plot specification using one of the possible variables | |||
#[[CDL - STATS|STATS]]: Starts the statistics block using one of the possible variables. Semantics demands the variable to be plotted normally as well. | |||
#ALL: Defines the variable to be taken from the [[Dayfile.txt|Dayfile]] and all data for that variable will be plotted (Note that the CMX parameter ''ChartMaxDays'' will not be used) | |||
#RECENT: Defines the variable to be governed by the CMX parameter ''GraphHours'' and are similar to the CMX RECENT graphs (though not equal). | |||
#AS: Defines the type of charting for that variable. | |||
#[[CDL - EVAL|EVAL]] [ ]: Defines an expression for the plot variable. The equation must be placed between the square brackets, space has no value here (does not act as separator). | |||
#COLOUR: Defines the colour of that variable. | |||
#ZINDEX: Defines the zIndex plane for that variable. | |||
#LINEWIDTH: Defines the linewidth for that variable. | |||
#OPACITY: Defines the opacity for that variable (important for area and column graphs) | |||
#AXIS: Gives the user the possibility to specify an axis when using the EVAL construct otherwise an error is generated. | |||
#ENDCHART: End the chart definition | |||
#OUTPUT: Gives an optional name of an outputfile which starts at the chart where it is defined. Any chart after this OUTPUT specifier goes to this OUTPUT until another OUTPUT is found. Only the first OUTPUT specifier accepts click events as defined by CONNECTSTO. | |||
The keywords for the actual parameters and the Graph Types speak for themselves. | |||
