Hi,
I would like to create a linear gauge with its background colour set based on 3 thresholds as shown in the below image.
There colour changes should use gradients as oppose to sudden changes to the colour.
There are two pointers in the plot, one has a diamond shape and the other one is a dashed line.


I've tried to replicate the plot using Nevron gauges (see the image below) but so far I have had issues setting the width of the gauge or setting multiple gradients at a precise cut-off point. To increase the width I've added extra axes but I cannot replicate the gradients as the maximum allowed gradient uses 2 colours and I couldn't give the precise value for the start and end point for the colours.


Could you please tell me how such a plot/gauge can be replicated in Nevron?
Should I use a Gauge or a Nevron chart? 

Thanks a lot in advance.
