Custom math equation in OID charting

I am using Ciena equipment and when I use the poller to show the RX dBm on a chart, the light level is showing as a large number. Can I use a custom math equation in the chart in order to make it look like light loss levels?

Example: Port 10 on a ciena device is receiving light at -23.565dBm, but it shows up as -235655.00. Can I divide this number by 10000 using a custom chart in order for it to properly show -23.565dBm?

I want to use a custom math equation to achieve the same, as it increases readability of values. Any suggestion / workarounds will be of great help.

How are you capturing the number? Is it possible to do the math (divide by 1000) in the UnDP definition?

Capturing by using OID 1.3.6.1.4.1.6141.2.60.4.1.1.1.1.105. The description of that OID states: "To convert back to dBM, convert this value to floating point and divide by 10,000." How do we do that in the UnDP or in Orion NCM?
