trend line using Dots chart in Raphael.js
I have to use g.raphaeljs library to create a scatterplot graph. Not only
that but i am trying to get a trend line as well, and am wondering how I
should go about this.
I was thinking of calculating the mean of the x axis and the y axis and
drawing a straight line based on slope.... but am still stuck.
Any help is appreciated.
Also the data used to plot the points on the dot chart is provided by a user.
