But it messy because each month I have to start a new row four rows down from the last month's, then copy and paste the formulae into the middle row between them.

There must be a much tidier way of doing this. 20 years ago I used 'MS Works" and it had a database section where you could make a "card " or something which automatically transfered the figures to a spreadsheet, which could then in turn do some calculations and then generate graphs, etc

I would also like to include units such as Therms and KWH and £s to make the records more usable. I hope somone can point me in the right direction, please.

Nowadays I use either Dropbox or Google Sheets for this sort of thing and find them very good. thanks, D

In Excel select the whole row, Ctl-C, then right click on the selected line and 'Insert copied cells' - keeps all of the formulas correct.

Over the years I have done various dynamic ranges so I can get a rolling average for the last 365 days (it isn't always the same number of rows).]]>

Thanks, I double space them to make them easier to read. But how do you extract the consumptions to do things with them, eg make a graph, or take an average? because they always appear on a newly created alternate line. Possibly you set up the whole blank year in advance and fill in the readings as time goes on?

I'm not sure what data youd want to average out but an obvious one would be your consumption per day rather than the consumption for a variable period which is somewhat meaningless when the period varies. To get the average per day for the period ending 1/11/2022, youd need the total consumption for the period divided by the number of days, so in cell B433 you would have =(B435-B431)/(A435-A431)]]>

However, if you are more adept at programming, I understand those in the know often use Node-RED (https://nodered.org/) to post readings to Grafana (https://grafana.com/) which can make all sorts of clever dashboards.]]>

I feel that Google sheets is very much like "Excel for the Web" which Dropbox uses, and also backs your work up on the web.

I had a quick look at Node-Red and it's forum, etc looks well used and friendly. Might have a dabble on there. Last year I was dabbling with Arduino programming and found it all very user unfriendly. However, I built a wood boiler controller with it on a Nano and it works resasonably well.

A B C D E F ETC
Date water water cons Gas con ETC

So A has all dates, C has all water consumption

In excel, I use charts loads and have a simple method for getting them done quickly. Likely similar in web version.

Click on date column then click on the columns you want to graph.(Directly on A, B etc. in header bit
This will highlight the whole column,
( Or you can use ctrl and "wipe" over the data column by column till you have everything you want to chart)
Then Insert chart , xy scatter and it will plot for you.
You can move some series to right hand (secondary axis) if scales are very different

Move chart to separate sheet/tab - then copy sheet to get different cuts on the data - deleting some items if you do not want them.

Good luck]]>

You said "Move chart to separate sheet/tab - then copy sheet to get different cuts on the data" - I have never used separate sheets ( nor realised it was possible) and I have always wanted to keep my data in one screen width to avoid scrolling, etc.
.
So I can use as many sheets as required for different purposes, just keeping my sheet No 1 for the raw data input?

If I delete the heading from those rows it will be awkward to be sure of filling in the readings in the correct cell. Or can I just use the data I want below the headings and tranfer it to the next sheet for processing?

For the vertical bar drag the left of the page.

You can keep the headings, these will be the test that comes up on the graph for the series (eg "Water cons")

Only reason for extra sheets is the graphs over the appear over the data - you can move them but easier in a separate sheet. Can then print chart
If you do all the data and set up nice axis and format,
I then copy this master to new tab/worksheet and remove some of the data series just by clicking on them and deleting. I am on office / excel 2010 so not latest versions.
Must be a youtube on drawing charts in your chosen spreadsheet.
I did a lot of data manipulation in previous days and excel could always do it rather than needing to go to databases.

You can link across worksheets if you have data on more than one sheet. press = then move to the point you want to use on the other sheet.]]>

I also use number formatting to include the units (which then looks good on the graphs).

Key thing is all data has to be on consecutive rows - remember it is data it isn't a presentation format.

I recently added the ability to generate and display the historical Max and Min.

Having charts on new sheets is a transformation!

A couple things I can't just find a solution for:
 Trying to customize the chart, I can't find how I got the label "blue" on to the dashed blue line, and it's not easy to see which column of figures each line relates to.

Future charts will not have as many lines, there will be multiple charts with different data sets soon.]]>

So say the orange line. One click only. Then right mouse then format data series.

If numbers very large for one series can move them to secondary (right hand axis) to let you see the smaller data easier. this is on format data series on excel as well.

If you delete the rows between the data labels at top and the actual data and include the data label in the selection of data/numbers it will bring it in. Or go to edit data and you can normally find it in there.



Keep working on your aster chart and then all the formatting will be there. Then copy the sheet with the master chart - expect google is same as excel. Click on the series/lines you want to delete and hit delete and they are gone from chart and legend.]]>

My autocorrect also just tried to autocorrect "autocorrect", which it thought should be "AutoCorrect".

I prefer MJ as the unit of energy (also capitalised, but with lower case k or upper case G). kWh is a ridiculously unscientific unit, it's guaranteed to cause confusion between work and power, and whoever thought of using h obviously didn't check what the universal unit of time is.

But I worked with two theoreticians, one of them thought that all thermodynamic energy should fundamentally be expressed in electron-volts as that is what it really is. The other thought that mass and energy are equivalent and so energy should be measured in kg.

I gave up on being pedantic about units after that, it was just no fun anymore, so I am fine with whatever units anyone wants to use, and however they spell them, if the meaning is clear enough.]]>

Looking at our gas bills, I couldn't work out how they had done their conversion from M3 to kWh but, for the time being, I have worked back the calculation from this web site which means I am multiplying the cubic meters by 32.156307 to get the kWh. https://www.theenergyshop.com/guides/how-to-convert-gas-units-to-kwh]]>

Perhaps there is an elegant solution? But so far it escapes me, and It is a drag making a fresh chart each time I want one with up - to -date data. Meantime I shall colour the colums I want for the chart to remind me which ones to use.

In column R youve got a value of 0.49 with an error under it. I dont know what formula youve got in that cell but let's say its doing something with the 0 in the cell to the left. In the cell with the error use the IF function to test if the value to the left is 0. If its 0 the result would be " " which displays nothing in the cell. If its anything other than 0 then run the current formula.

What Ive written will likely not make much sense until you read up on the IF function!!]]>

When you paste in a screen shot make sure the cell youre talking about is selected and the formula in that cell is displayed at the top of the page- its a bit difficult to understand whats happening if you can't see the data. Also make sure the column and row references are in the screen shot- they are in the last shot but not the one before. Makes it so much easier to comment!]]>
