high quality graph of nice 0-100 analog scale?
I have a few slow-motion drives with pointers that I'd like to equip
with simple log scales. I have tried to split a half-circle scale by means of a compass, and found it to be quite doable, but 1) time-consuming, 2) messy, 2) leading to power-of-two end-of scale values (obviously) that are anything but intuitive. I am not an binary / octal / hex / kind of guy, and have no affinity for scales that end at 64 or 128 or G_d forbid 256. I also tried making a 0-100 scale by means of Excel / PowerPoint / Openoffice, but their rendering hits very soon an unsightly rough degree of approximation. Is there any place on the web whence I can download some high-definition graph for a 0-100 or 0-180 scale? I'd print it out in large format and then reduce it to the size I need by means of an ANALOG photocopier. TIA Spammy |

Nice and very useful, but appears to not do log scales as I believe
the OP wants. I hacked a simple Excel spreadsheet that would do fine, except for the fact that Excel plots INCORRECT size segments sometimes! Grrrr. Otherwise seems like it would be fine; it prints just fine, to whatever your printer resolution is. If the OP wants to try it in Excel perhaps a different way than he first tried, here's what I did... o One cell for degrees span, referenced in next-to-last step. o Make a column with the values where you want tics (e.g., 1, 2, 4, 6, 8, 10, 20, 40, 60, 80, 100). There can be any number of them, at any values (in sequence, of course). o Next column over, take the log of the tic values o Next column over, take the differences between adjacent values in previous (log) column. There will be n-1 of them. o Just below last cell of differences column, create a cell with sum(column_above)*(360-degrees_span)/degrees_span in it. o Create a "donut" plot of the n values in the last column. Adjust the colors to be all the same (or not, as you please) and the inner circle to be the radius you want. This doesn't label the tics, but you should be able to do that in other progs if you want. And the tics are all the same length, which is suboptimal. Should be easy to do in Scilab, too, and use Ghostscript to print (like Panel and Dial do). That gives the ability to make different size tics and to label them.

Thank you everyone!
I haven't tried "Meter", but "Dial" already made me the proud owner of a nicely printed 0-100 linear scale. Question: I had to do a screen capture and print via IrfanView, as the Radius setting had no effect on the printed size. Did I do something wrong? (However, using the screen capture, the result is excellent!) Re. log scale: don't you get any serious problems with fine rendering / printing? My PC/Video/printer work very well with Meter + IrfanView, but I can't get anything decent out of Excel/Open Office, as both approximate fine divisions too roughly for any practical use, even when doing HUGE pie charts. Thanks again, sooner or later I'll post pics of the new rig. It will (should) be a broad tuning-range HF regen with a highly repositionable, crystal referenced bandspread (either one generic 0-100 linear scale with tuning graph book, or perhaps a series of slide-in tuning cards, both so cutely retro!) plus switchable wide/phone/CW audio bandpass filtering, and a few other tricks. Also, by the way, do you know of anyone using a film scale + lamp + lens to PROJECT the tuning scale in a homemade device? This would be sooo cooool! I'd even be tempted to print in the names of a selection of broadcasters, coastal stations, nets, QPR windows, USN fax, GCSS, whatever.... Spammy |

The radius should affect the printed result. *HOWEVER* - the radius in the
Windows version is in pixels. On your printer, pixels are usually pretty small these days, so you need to make the dial absolutely huge on the screen to print reasonably. Most commonly printers are 300 dpi (although some newer ones are a lot higher) so a radius setting of 150 would give you a 1 inch diameter dial. ... "SpamLover" wrote in message om...

Perfect! Now I can get excellent results. Thank you! |
