Customizing Core-Plot Iphone graph plot

I wish to customize the core plot graph library for Iphone a bit. I got some nice tutorials on this, for eg: http://www.raywenderlich.com/13271/how-to-draw-graphs-with-core-plot-part-2

But, in this tutorial one can draw scatter plot graphs that start with 0, and then we can increment the Y-axis accordingly.

I want the graph to be a very relative one (based on the input).

for eg: If I have 7 points viz:(82,83,84,85,86,87,88).

Then I want a graph that will start from 80(Y-min) and end on 90(Y-max).

Can anyone please help me out in this.

Set the yRange on the plot space. Plot ranges are similar to NSRange; you specify the starting location (80) and the length of the range (10).

plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(80.0)
                                                length:CPTDecimalFromDouble(10.0)];
