Donut Chart Extension Recommendations

kdaniels-obrien — Mon, 03 Feb 2020 14:27:31 GMT

Hi,

I am looking for recommendations for an extension that offers a donut/circular gauge. I need something that works using only one measure where I can set gauge colors and width.

Thanks!

What are you trying to achieve. This is possible in the standard gauge.

I want to achieve something like a gauge but I am looking for a visualization that will be more clear at a quick glance. The needle on the gauges are some what small. For example, the customer has asked for a donut gauge that shows a red progress bar when number is very low, a yellow progress bar when numbers are fair and a green progress bar when number are good. I've attached a picture below of a similar chart. If you know of a way to make the regular gauge behave this way, that would be another great solution! Thanks in advance! 🙂

The regular/standard pie chart can be viewed as a donut with conditional coloring, or the radial gauge can have conditional coloring as well using segments.

Thank you! I have figured out conditional coloring with the radial gauges.

I have defined a variable that gives the value of the radial gauge, such as quality. I also have defined vRedThreshold and vYellowThreshold as variables so that a user can change the thresholds without having to edit the limits.

Right now I have my red zone as: =if(vMyVariable < vRedThreshold , vMyVariable, 0) and my green zone right now is: vMyVariable

I want to add a yellow segment in between red and green zone.. What kind of expression should I use?

Just define the middle segment as yellow in the properties
