Hello...

Few question about history graph.

-Is it possible to set default "Time" value? As default as is (One minute) is too short. I prefer "Last week".

-How to set scale range of signal? For example I had temperature reading around 28 centigrade -+1 degree. But graph by default show from -20 to 40 degrees. So I see just flat line. If I set scale from 27 to 29 the values are rounded from 20 to 30 degrees so near flat line again.

-I monitor grid voltage and I had 3 history windows for each phase.
is it possible to join all 3 voltages in same hist window?


Screen shoot show the temperature graph

- No.
- There is no other way to set the scale.
- Use a PlotGroup object.

Hello...

Still no happy with layout. I don't know what I do wrong.
So there is a bunch of pictures to show what bother me.

When I open temperature history I just select All Time and refresh.
I get that:

So As range is just to wide to look at the differences I set the range like that:


2SetupTemp_2015-10-14.png



So I expect to have two degrees scale. But I got that:


3ResultTemp.png



Other graph for voltage has similar trouble:


4DefVolt.png


5SetupVolt_2015-10-14.png


6ResultVolt.png








So what I do wrong?!?
Is there a way to setup how many horizontal lines is on screen? (aka granularity) and to have range as entered?

Thanks and sorry for all the pictures.

Hi Slavko,

To be able to draw a proper scale, some rounding is made and maybe it doen't work perfectly in all cases. If your not satified with the behaviour you just download the source code and improve the code, that's how open source is supposed to work.

I think that changing source is little to much for me. Probably will take a week to find correct source file... And my programming knowledge is far from brilliant :ohmy:

I'm having the same issues with the scaling. I've been trying to find the source code for the history trends, but can't seem to find the right one. Could someone please tell me which pwg file I need to change?
