Some graphing succestions..
As you start buffer mode, both channels are on autorange. And in most cases, there will be crazy noise visible for a while and current values can’t really be seen, as graph starts leaning to either end of visible area and very small numerical values are partly off screen (and changing all the time)..
So, what about setting margins to graph mode autoranging, like 20% on both sides, in which graph can go, say 3/4 without changing visible range and when that last 5% gets hit, autorange to 20% margin again? Less range changes –> easier to read. (+ of course about similar values at the other end of graph, 20-25% margin not used, range closest value to 5-10% or something.)
Then, numerical display on graph mode? Latest/min/max/etc.. Again, easier to see whats happening. Those may be more usable with graph, than on the normal multimeter screen..
Math channel with real values would be nice to graph. Now its impossible to live graph thermocouple, if you want also to know what the temperature is. Or current via ct-clamp, if we get that “free” math channel for live ratio calculations.
