Rain vs Evapotranspiration

[HansR]

- as you can see in the image, the Normal Yearly Rainfall text is under the layer. Can it be moved to the front?

Yes, another Z-plane but also another colour because they're both red and the line will disappear against the red area.
I will change both in next version.

- in the CUstrings file I cannot find and translate the text Normal Yearly Rainfall, Daily Rain, Daliy EVT into my language.

Indeed. Will make all three translatable (actually: four, see below).
(note: Normal Yearly Rainfall (and also Station Yearly Rainfall) are amongs the oldest strings in CUtils and nobody ever noticed

Welcome to the North West Slopes & Plains......

Edit:- And Daily Rain.

And BTW, if you make your selection from 1 july it may look better because you then start in the winter period (I assume you start your rain period in july?).

Pretty sure Mine starts in January, as per what the BOM do here.
Always considered we should be opposite, but seems they record based on a calendar year.

Edit: Hard to see the recent days rain on the chart, given that the scale is up aroung the 1200mm mark & daily figures were in the 3 to 30mm Range.
(November 3 & onwards).

Not sure what sort of scaling along the average would make it look appropriate.

I still think a simple delta plot as suggested by @freddie may be useful.

It is a deltaplot: arearange de facto is a delta plot. If the difference becomes negative I colour it red otherwise it becomes green.

It's a delta plot superimposed on a running total. This causes scale issues as totals grow. If you plot the pure delta about the origin line as I suggested then scale doesn't really come in to it - unless, of course, if the delta itself becomes large.

In reading charts scaling is of the essence. If you look at my second example - the area's coloured - you see that 2022 has a very small period of drought, 2020 a large one and the other two years none. I don't think plotting only the difference between rain and EVT would supply the info my way of charting does. The initial zoom level (1 year) is no coincidence: it shows a period over which the relation charted has its periodic importance and beside that: the Y-axis scale shows the relative importance of a possible dry period and will always more or less be the same.

So in short: you would like the opposite of what is intentional and what I see as important and has been deliberately avoided.

NOTE: in the first chart when starting the CUtils website it by default - it can be changed/removed by the user - shows the overview chart and you may have noticed that the pressure scale also deviates from what is normal in the CMX world: the scale has a memory for the max/min pressure records that station has ever seen and large barometer changes will show better and in context. As such with a longer period high pressure - e.g. 1020 hPa - the pressure line remains almost flat and hardly moves. CMX pressure will then start to have large amplitudes for small changes because the scale will fall back to e.g. 1020 +/- 5 hPa. I think my barometer is better

So in short: I assume we can agree to differ of opinion on how to graph and how to scale.

@freddie, @mcrossley: As a result of your remarks I discussed the chart with a friend of mine, a fellow agricultural engineer, looking at all possibilities and together we concluded that my chart contains most information though the title should express that we are looking at cumulative rain and EVT. Having said that, this chart is likely the most discussed chart in CumulusUtils thanks to your remarks.

Thanks for that even if you disagree

Isn't an agricultural engineer just a fancy name for a mechanic?

No. An agricultural engineer thinks and designs agriculture which may involve machines. It also involves environmental, biological, plant structural (forest structure), entomological, climatological, meteorological etc... theory and practical design. The last decades DNA engineering also has become part of it. And no, an agricultural engineer is not supposed to know all about everything. Why? Because all those aspects attribute to food production which needs to keep up with exponential growth. A formidable and most likely impossible task. I might even add diplomacy as an agricultural field of study.
(This is the short answer)
