==== Version 6.0.0 (21/07/2021) ====
#ChartsCompiler: Finalisation.
#Website: Added SolarHours to the Solar text panel
#Website: Made the position of the panels user definable (See the new [[Dashboard]] Wiki page)
==== Version 5.6.2 (25/06/2021) ====
#Misc Charts: Fixed bug in counting days in thermal season chart.
#Misc Charts: Fixed bug in thermal season chart, it now works correctly on the southern hemisphere. (Tip: use modified thermal boundaries to see useful seasons for your latitude)
#Misc Charts: Set the default for ''Thermal Seasons chart'' to false
#ChartsCompiler: Implemented the POW function (raise a double to some power: POW(number, power). Implemented as Math.pow javascript function
#ChartsCompiler: Implemented the SQRT function as Math.sqrt function
#ChartsCompiler: Added equations and charts to the CutilsCharts.def
#ChartsCompiler: Implemented multiple equation subtitutions e.g. (Avp stands for : Actual Vapour Pressure):
Psat2008 EVAL [ Humidity/100 * 6.112 * EXP(17.62*Temperature/(243.12+Temperature)) ]
Avp Eval [ Humidity / 100 * Psat2008 ]
AppTemp Eval [ Temperature + 0.33 * Avp - 0.7 * WindSpeed / 3.6 - 4.0 ]
==== Version 5.6.1 (17/06/2021) ====
#ChartsCompiler: Fixed bug in counting brackets in equations under some conditions.
==== Version 5.6.0 (13/06/2021) ====
#MeteoCam: First release of a simple MeteoCam (Webcam) module. See [[MeteoCam|Wiki]].
#ChartsCompiler: Lines starting with a semicolon [;] are now treated as comment.
#ChartsCompiler: Equations section added (see [[Charts_Definition_Language_(CDL)|wiki for CDL]]) and they can be substituted in other EVAL equations
#ChartsCompiler: EVAL and STATS now work for both the ALL and the RECENT ranges
NOTE: The combination of the EQUATIONS block and the EVAL of PLOT makes it possible to evaluate more complex (as in meteorological) Equations. The Possibility of combining Plotvariables and calculations makes it possible to evaluate different approximations for e.g. Dewpoint. Both clarified by the example below. The release contains as usual a complete set of test charts. Sometimes with meaning, sometimes just for testing. This set of test charts is an example and a test. Nothing more.
Equations
test1 EVAL [ Humidity/100 * 6.112 ]
test2 EVAL [ EXP(17.62*Temperature/(243.12+Temperature)) ]
; Documentation:
; https://iridl.ldeo.columbia.edu/dochelp/QA/Basic/dewpoint.html
; Compare the Dewpoint from Cumulus with a calculated approximation
; Later I will enter the Cumulus Calculation and have the Dewpoint be produced by the Davis station
; Nice comparison

==== Version 5.5.2 (06/06/2021) ====
#pwsFWI: the Current pwsFWI button now has forced text colour (not inherited by the background)
==== Version 5.5.1 (03/06/2021) ====
#Compiler: Value arrays need to be reinitialised when the chart remains open and has its periodic (ftp upload frequency) refresh.
#pwsFWI: the Current pwsFWI button moved to the Left Header Text position to improve handling on a portrait held tablet
#General: Provided for non-contiguous data series (missing years and/or months).
==== Version 5.5.0 (29/05/2021) ====
#Distribution: file ''CUabout.txt'' has a name change: CUserAbout-example.txt. CUserAbout.txt - if it exists - will be automatically uploaded with the package
#Distribution: file CUsermenu.txt will be automatically uploaded if it exists
#Distribution: file ''CUlicense.txt'' has been removed and replaced by the file LICENSE (with identical content to the website menu choice)
#Compiler: Errorhandling of Expression in case of error, now gives an error in the definition of the charts and fallback to the default charts (it was a warning)
#Compiler: STATS and PLOT are now handled as equal entry points of the PLOT section of the CHART (see prev version of CDL image to appreciate the difference)
#Compiler: a PLOT variable may now have a non-keyword name but if so, it '''MUST''' be followed by an equation which contains a valid Plotvariable, if not an error is generated.
#Compiler: And if a PLOT has an Eval equation it '''MUST''' now have a non-keyword name to prevent confusion and make a unique legend entry (useful for modification or translation)
#Compiler: Added the function LN (being the natural logarithm of its argument)
#Compiler: Added the function EXP (being the power function with base ''e'')
#Compiler: All Plotvariables can be used in one single equation to be combined with operators and functions '''NOTE: this must be seen as beta function''' as it is impossible to check all combinations of variables, operators and functions. I don't expect this to work flawlessly although confident. Just play with it and provide me with observations and questions for functionality.
#Compiler: The SUM function can only be used once per chart
#Wiki: Updates conform development (please notify voids or unclarities)
'''NOTE:'''
#Because meteo-equations can reach a certain complexity (definitely when written on a single line) a change is considered which should make it possible to use Plotvariables as intermediate calculations or have a definition of partial equations (not plotted) which you might use in Plot. As an example (see the last chart below) One might consider calculating a dewpoint with the Actual Vapour pressure as an intermediate equation.
#A second change which is considered is making the EVAL and STATS available for the RECENT parameters as well
However, the side effects of the above may be larger than expected, so it requires some study. In the mean time : have fun!
'''NOTE:'''
All calculations and array handling in the generated code are totally unsophisticated and non-optimised. This will only change slowly as performance is astonishingly good, beyond expectations, even on my old tablet and phone. Performance reports are welcome.
Below you find three test charts as examples to show what is now possible (the full testset is as always in ''CutilsCharts-example.def'' in the distribution and viewable on my site):
CHART DailyTemp TITLE Temp with statistics offset 5
PLOT ALL AverageTemp colour pink
PLOT ALL sumAverageTemp EVAL [ ln(Sum(AverageTemp-5)) ] COLOUR green AXIS DegreeDays
STATS AverageTemp SMA COLOUR crimson
EndChart Output Statistics.txt
CHART DailyRain TITLE Rain with statistics
PLOT ALL RainFall colour CornflowerBlue as column
PLOT ALL sumRainFall EVAL [ exp(ln(SUM( RainFall))) ] COLOUR crimson AXIS Free
STATS RainFall SMA colour green
EndChart
Chart MyDewPoint Title Dewpoint calculations in CDL
Plot all minBarometer
Plot all maxBarometer
Plot All ActualVapourPressure Eval [ MinHumidity/100 * 6.112 * EXP(17.62*AverageTemp/(243.12+AverageTemp)) ] Axis Pressure
EndChart
==== Version 5.4.0 (21/05/2021)) ====
#Language: Create a distinguishable legend in the chart for the columnrange variable (section [Compiler] in CUstringsXX).
