I’m trying to draw a graph using the coreplot library. I’m looking for a way to change the dataLineStyle of the graph so that all the dots will be connected in a straight line, without any playful turns. If needed, I can provide more information.
Is there any way to achieve this?
[EDIT]
I have included a picture to better understand what I’m talking about. I would not like the Graph Line to go above or under the data points.

Regression lines aren’t built into Core Plot. You can use one scatterplot to draw the data points with just plot symbols and no data line. Use a second scatter plot to draw the regression line. It only needs two data points, one for each end of the line. You’ll have to compute the regression coefficients yourself.
The lines connecting the data points are controlled by the
interpolationproperty. The default isCPTScatterPlotInterpolationLinearwhich is what you want.
