[libreoffice-users] Calc charts, data in record form
All, Looks like I will be keeping my data in Calc for a while - until we have a better idea of what we want (changing a database is a lot of work). However, I need to do some charts, and I have not figured out how to get Calc to give me what I want, so I need a pointer or two. I want line charts, with multiple curves per axis (up to 8). Perhaps something like this: http://www.indiabix.com/data-interpretation/line-charts/ The data is arranged in record format like this: Date Location TemperatureHumidity - - -- - 7/1/14Syracuse 71 79% 7/1/14Albany68 70% 7/1/14Rochester 69 70% 7/8/14Syracuse 82 68% 7/8/14Albany79 67% 7/8/14Rochester 75 66% So how do I end up with one chart that shows three curves for the three cities over time (Location and Date on the X-axis, Temperature on the Y-axis)? I have looked at the docs amd did some Googling, but so far I'm stumped. I know that someone has done this, so there is likely a very easy want to do it.

Er, you presumably want just the date on the horizontal axis, with locations represented by separate lines. What you need to do is to assemble a table in an appropriate fashion for a chart to be possible. You will probably want four columns - for dates and the three locations - with the temperature values in the body of the table. That way, there would be one row for each date. Creating the chart from this would be simple. So how to achieve that table? Well, one way would be simply to enter the data that way in the first place. However the data arises, it may be most convenient to massage it into the required form as you enter it. Note that the way you are currently entering data, you have each date entered three times and each location very many times. That's never a good idea. How many weeks before you enter Sryacuse by mistake? Alternatively, you can simply extract what you need from your existing table into the required one. Your date column would be entered manually or - better if appropriate - filled down from the first two weeks' dates. The body of the table would then have formulae which retrieved the appropriate data from the original table. You might be able to do this using the VLOOKUP() function, but it won't be simple, as you have two conditions to search for: date and location. The simplest solution might be to sort your original table by location (or you could enter the data into three tables in the first place), and then to use VLOOKUP() to search for the appropriate date and harvest the temperature value from within just the relevant part of the original table - that now containing the values for each location. It's probably very much easier if you create three tables in the first place - one for each location. http://www.fastmail.fm - Does exactly what it says on the tin Really? So it sends your mail more quickly than other systems? Wow! I trust this helps.

The way the data is set up is legacy in that it is from a form used previously. The intent was to create database-like records where data from 12 cities is updated each week. To help eliminate entry mistakes, I use validation so Syracuse never becomes something else. I have made some progress playing with chart settings, but still not where I need to be. I will give the lookup functions a try.
