i am not sure how to interpret it so that i can do some equalizing.
need suggestion so thanks guys in advance.

You have to define the parameters on the "X"(horizontal) and "Y" (vertical) axis . Do you have a link to the graph being shown?

Seems to me like that's a graph a driver or speaker manufacturer would supply with their driver/speaker. An in-room measurement would be substantially more useful for determining what truly needs adjustment.

By the way, what kind of equalizer do you access to have? Graphical, parametric (how many bands?), or is it simply a tone control? Yet to be decided?

yeah bascially i like to know how to interpret such graphs. using a 5 band digital equalizer, +/-2db with each tune, at 65, 250, 1k, 4k, 18k.

is it possible to tune for a flatter response. which do i tune up or down

X: db ratings
Y: frequency
red line: phase inverted

i just like a very rough suggestion. accuracy is not important. thanks.

Well, a couple of issues before we talk turkey:)
The numbers on the graph is smeared and cannot make out where the peaks are as that is what you want to cut/reduce first.
Second, is this graph an in room frequency response? If not, it has no meaning when you equalize.
third, a 5 band EQ is not much help.
But, you want to reduce the tops, not boost the valleys.
