I'm trying to add the equation for a linear regression line to a scatter plot that I have made. I first plotted my data points then used the polyfit function to add a first-order line to my plot. Now I want the equation of the line in y = mx + b form to...
slope, intercept, r_value, p_value, std_err = stats.linregress(x, y) line = [slope*ii for ii in x] + intercept plt.plot(x, y, 'o', x, line) plt.annotate('R=%.2f\n' % (r_value), xy=(0.05, 0.9), xycoords='axes fraction',color='red') ...
A nice way to add info and highlight trend in a scatter plot is to add aregression lineon top of the dots. Thanks to itsregplot()andlmplot()function, it's quite easy! The main difference between those 2 functions are that: regplot()is used for simple scatter plot with a trend line...

Connected scatterplot using base RBasic R also allows to build connected scatterplot thanks to the `line()` function. You just need to use the `b` option of the `type` argument. See examples below. How to add a legend to base R plot The legend() function allows to add a legend. ...
A regression equation is calculated and the associated trend line is plotted on scatter plots. The trend line models the relationship between the two variables, with both linear (Linear) and nonlinear (Exponential,Logarithmic,Power, andPolynomial) trend line options available. The R² value quant...
Enhanced scatter plots: car::scatterplot() The functionscatterplot() [incarpackage] makes enhanced scatter plots, with box plots in the margins, a non-parametric regression smooth, smoothed conditional spread, outlier identification, and a regression line, … ...
