====Why the value is not correct when the step is 900====?

[caomm1982]

Hello, I have a question ,pls.

I have a pic, the poller interval is 300, the step is 900, the monitored values are all integer , but the y axis has some float values,and the value was not I expected ! If I set the step to 300, then the y axis value will change to correct integer ones.

Anyone can tell me why, what should I do to get correct values while the step is 900 ?
Thank you,very much!

When changing step values, you have to take care for a lot of parameters. Find a HowTo on 1 min polling in the howto section, tackeling the same stuff (it only changes from 300 to 60, so the math differs a bit but the magic is the same).
