Both this and the Centre building itself are equipped with photovoltaic solar panels to convert sunlight into electricity. The University needed to assess the performance of the solar panels, and chose Windmill software to do so. The Windmill system calculates the panels' power output and conversion efficiency, displaying the cumulative and instantaneous values both graphically and as a table. Windmill also logs temperature, wind speed, solar radiation, direct current, DC volts, power into the electricity grid and power out of the grid. The data is acquired using Microlink 1500 units provided by Biodata (www.microlink.co.uk). These units are distributed around the two buildings, communicating with the central PC over RS485 cables. For more information about monitoring energy, please contact Windmill Software - [email protected] Previous issues of Monitor have discussed temperature and wind speed measurement. These are archived at http://www.windmill.co.uk/thermocouple.html and http://www.windmill.co.uk/monitor23.html ________________________________________________________ Exhibitions and Conferences ________________________________________________________ Continuing our bimonthly list of exhibitions and conferences related to data acquisition and control.

Continuing with this theme therefore, here are some other resources with useful charting tips, tricks and tutorials. Usenet: microsoft.public.excel.charting http://groups.google.com/ Chances are that whatever your problem, either it will already have been answered or someone will be able to offer a solution or explanation. Make sure you read the closest thing they have to a FAQ before posting, namely Chip Pearson's "Hints And Tips For New Posters In The Excel Newsgroups". http://www.cpearson.com/excel/newposte.htm Application Professionals http://www.appspro.com/utilities/Labeler.asp A very commonly requested Excel feature is the ability to add labels to XY chart data points. Here you can download a utility to do just that. Two versions are available - one for Excel 5/95 and one for Excel 97/2000. Stephen Bullen's Excel page http://www.bmsltd.co.uk/Excel/Default.htm Amongst other examples, has a series of charting utilities. Unlike many sites this one clearly shows under which version of Excel each spreadsheet example will work. element k journals http://www.elementkjournals.com/ime/9808/ime9881.htm Explains how to plot only the most recent data, for example data from the last 30 days. As new data arrives, the chart automatically updates. Excel Charting Tricks from PC Magazine http://www.zdnet.com/pcmag/stories/solutions/ A tutorial incorporating a series of charting tips. The Excel Logic Page http://geocities.com/aaronblood/pages/charts.html Examples of sophisticated use of charts. ________________________________________________________ * Copyright Windmill Software Ltd * Reprinting permitted with this notice included * For more articles see http://www.windmill.co.uk We are happy for you to copy and distribute this newsletter, and use extracts from it on your own web site or publication, providing the above notice is included and a link back to our website is in place.
