Radar Charts
Is it possible to control the position of the first point on a radar chart? I
need to essentially rotait the whole chart so that the first data point is offset, rather than at 12o'clock. Thanks |

Hi,
The radar chart does not allow this. You can of course create your own radar looking chart using a XY Scatter, multiple series to draw axes, gridlines and datalines plus some maths knowledge in order to calculate all the positions.

I wanted to do this recently for a polar area graph (or "Nightingale rose") I was designing, and I couldn't see any way to do it. Your only option seems to be to move data between the top and bottom of your chart ranges until the twelve o'clock position looks right. -- Del Cotter NB Personal replies to this post will send email to , which goes to a spam folder-- please send your email to del3 instead. |

Does Stephen Bullen's polar plot help?

That's an XY Chart, so I don't think it gets us any further along: what we're looking for is the equivalent of the "Angle of first slice" spinner in Pie Charts, and the XY Chart type is as devoid of such built-in controls as the Radar Chart. I'm happy enough to just move the data if it's necessary, but if Curly needs a more dynamic solution, I'd suggest something involving INDEX and MOD to cycle round the numbers: =INDEX(original_range,1+MOD(cell-offset,COUNTA(original_range))) where "offset" is a number you type into another cell. Every time you advance "offset" by one, you advance the data one place clockwise around the radar chart. "cell" is one of a range of numbers starting from 0 and ending at one less than the count of rows in the original range. So... offset 0 orig cells formula a 0 a b 1 b c 2 c d 3 d but... offset 1 orig cells formula a 0 d b 1 a c 2 b d 3 c ....and so on. You see why I just did it by hand instead :-) Oh, one other thing. This just moves the radar chart points round by one place, it doesn't move the twelve o'clock position, so it still doesn't have the precision of the Pie Chart angle control. -- Del Cotter NB Personal replies to this post will send email to , which goes to a spam folder-- please send your email to del3 instead. |

Del -
I was referring more to your Nightingale Rose project. I don't know about the needs of the OP. A lot of applications that people use radar charts for are better suited to parallel coordinates charts. Coincidentally, I just wrote a tutorial on these: http://peltiertech.com/Excel/Charts/ParallelCoord.html - Jon ------- Jon Peltier, Microsoft Excel MVP Tutorials and Custom Solutions Peltier Technical Services, Inc. - http://PeltierTech.com _______ "Del Cotter" wrote in message ...
