negative values not display correctly on graph with custom plugin

[djsakisd]

Hi

I created some custom plugins for some graphs i need.. There are 2 values reported here : min & max and both have negative values.

In graphs only one negative value is reported as graph.. for example if the 2 values are -3 & -9 only -3 is displayed on graph.

If i revert the values to be possitive (ex 3 & 9 ) they are graphed fine.

Output from plugin on agent reports fine and also if i create some counters they report fine.. so only issue is the graphs..
