My apologies for bumping this. I need to correct the version of NPM indicated in my question. I am actually running NPM version 12.0.1. I am still hoping to find a way to use a zoom range with a custom chart (similar to what I have always been able to use with the "custom object resource".''
I have the same question. I've created a Custom Chart (several actually) and want it to initially display the last 24 hours of data, but then to be able to zoom out to see the last 30 days (or part thereof), and there doesn't seem to be a way to do this. Loading 30 days by default can take a while when you have several of these Custom Charts on one page.
What I'm doing is aggregating several interfaces onto Stacked Colum graphs to give me an overview of traffic flow in certain parts of the network.
I'm running Orion Platform Version 2017.1.2, NPM 12.1.
Hoping there's an answer out there somewhere...
I have the exact same issue, I was only able to plot the component data in a Custom Chart to discover that we cannot specify the default zoom range.
Hopefully this can be fixed.
