Picture of Speedometer Graph in Excel
I have seen some speedometers in some of the professional dashboards. I thought how? How do they do it? So I did some preliminary research and came up with this speedometer. Kindly comment for any changes required. 

Step 1: Insert Values

Open a new workbook and enter
Value in cell B2
Max in cell C2
27 in cell B3 (exact value)
100 in cell C3 (maximum value)

Hi there, not sure if you have answered this question before but I have 2 conundrums hoping you can solve:

1) I sometimes have negative values which need to be "in the green" so to speak, while positive values also need to be in the "green". For example -$1000 to +$10000 should be represented as green while anything below -$1000 should progressively become "redder" or worse.

2) I also cannot have the gauge going past the horizontal axis (as my users play around with the gauge it can tend to spit out a range of results which makes it go right round into "transparent" territory. How best can I fix this?

Thanks I find this tutorial definitely the best on the web and most appreciate the maths behind it!

You'll see in the example that cash flow (-$1570 should be in the green - while should the cash flow be positive then this should be even more green!) and invested I need to have the same issue (as the negative sign is messing things up! I tried making it an absolute value but that didn't work :( )

Cool! Thanks for letting me know. I don't know if I can fix these issues. Rest assured that I will do a brainstorm for the same. If I can fix this, will surely do the victory dance. Will keep you updated.

There will be two victory dances. #nopressure

Great instructions ... easy to follow and easy to customize to my specific application.

I do have one question ... I need to copy as a link the final "speedometer graph" into Word & Powerpoint (as I am building an editable template)... but when I try to do this in Word, it separates the two charts ... so my only solution is to copy and paste as a picture (which very problematic)

Any thoughts?

Thanks

Damn! That is a serious issue you mentioned. I was totally devastated for some time. Got the solution!
After pasting into word right click on the graph which you want to put on top and set it's wrap value as in front of text. Now you can drag it over the other graph.
See the image for more info.
Hope it helps. Kindly revert if require more info.

You could use XLGauge (www.pendragonsystems.com)
There was also a speedo graph with an attractive customizable background here (www.ExcelDashboardWidgets.com)

I love this it's so helpful, especially the example.

This will be useful to create dashboards in excel itself.

Very nicely done! It's always fun to see some actual mathematics used in Excel (pity you have to do the conversion from degrees to radians by hand, though).
PKM kelseymh5 years ago
Excel has a built-in function known as RADIANS(angle) where angle is the angle in degrees you wish to convert to radians. For example, the Excel expression used to convert 270° to radians would be RADIANS(270) which equals 4.712389 radians

From here

You can simplify the expressions to

B7: =-COS(RADIANS(((B3*180/C3))))
C7: =SIN(RADIANS(((B3*180/C3))))

Thanks PKM.

Its really an easy way !!!

Thanks PKM for the simplification. I got the formulae, but did not had the time to update the instructable. Appreciated!

Wonderful! Now the folks at work can be amazed by "MacroMan"'s graphing abilities as well. We'll keep it our secret right? ; ]
I've had a play around with this today: if one sets things up like in the attached pic, one can enter data (eg scores out of 20) on another sheet and have the graph reflect this. And yeah, there are many and better ways of setting things up, - as I said, just a play around!
Adding the Redline cell easily allows one to change where the red extends to, which might be useful if one has to use this graph for different criteria.
Well done artworker: I'd not have come up with that one on my own, so thanks! Any other graph tricks you can show us? I'd be keen...

This is a very cool method for making data visual in a different way! Cool.

Good work- you'll have me out of a job!  I can't think of a way to improve this graph (simplicity is the key to a good dashboard) but for people who would want to customise theirs further you might want to explain the math you used in step 3 to get the points for the speedometer needle.

For more fun with this you could play with the Data -> From Web tool- it gets the contents of part of a website into your spreadsheet.  If the thing you want your dashboard speedometer to show is available on the web somewhere, you can probably get it this way.

Thanks PKM for the comment. It is a nice idea to have a web query connected to this graph. I will implement this on my share price sheet. As for the formula shown, I am looking for words to explain the same. Will do it ASAP.
