Plot blocks can be repeated as many times as you wish but different parameters can result in many yAxis (making the plot area smaller) and the chart may become crowded and unreadable. Experiment and try-out. | Plot blocks can be repeated as many times as you wish but different parameters can result in many yAxis (making the plot area smaller) and the chart may become crowded and unreadable.

Syntactically the | Syntactically the [[CDL - STATS|STATS]] block can be many as well but it requires semantically the Plotvariable of which you want statistics to be plotted normally. So you can have e.g. three [[CDL - STATS|STATS]] blocks for one PLOT block. | ||

The | ==== 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. | |||

ColumnRange only works for DAILY and ALL range specifiers. If the Max and Min lines of the range must be shown, they need to be specified as a separate line. The range can be specified for either Min or Max, the range will automatically be applied and no line will be shown. The ColumnRange is valid for all variables in the datafile with a Max/Min range: ''Temperature, Dewpoint, FeelsLike'' (and other derivatives), ''Barometer'' and ''Humidity''. Other variables will generate an error. | ColumnRange only works for DAILY and ALL range specifiers. If the Max and Min lines of the range must be shown, they need to be specified as a separate line.

This only has meaning if there is an EVAL with a valid expression present. As an EVAL may modify the value of the plot variable to something completely different, the original Axis belonging to that plot variable may be useless or scale wrongly. Therefore you can choose your own Axis. If there is no valid equation, a warning is given and no axis is generated. | This only has meaning if there is an [[CDL - EVAL|EVAL]] with a valid expression present.
