Trying to get a line of best fit through my points. The best fit line or optimal relationship can be achieved by minimizing the distances of the data points from the purposed line. Lsline ignores data points that are connected with solid dashed or dash-dot lines - -- or - because it does not consider them to be scatter plots.

In this article, we are going to see how to connect scatter plot points with lines in matplotlib. Accepted Answer. matlab line of best fit scatter plot. In Matlab, the popular and most effective technique that is used to apply linear fit is known as "Least-squares fit" method which states that the line of best fit is adjusted in such a way that the square of the difference between the actual and predicted values (error) is minimum. They can plot two-dimensional graphics that can be enhanced by mapping up to three additional variables while using the semantics of hue, size, and style parameters.
