Pyplot plot function

Question

Given below is the code for plotting points using pyplot.

x1=300+p[k]*math.cos(val[thetaval])
y1=300+p[k]*math.sin(val[thetaval])
plt.plot(x1,y1,'k.')

The plotting is working fine, the problem is, if I want to plot it as a point I am specifying the dot in 'k.' inside the plot function. The output is something like:

The width of the black line/curve that I am plotting is much more that needed. How to reduce it?

Answer 1

It seems that you are not plotting a line but a series of small points. Maybe if you try setting the markersize argument of the plot function could work.

Answer 2

Looking into the documentation of plot() you can find "linewidth"

So use:

plt.plot(x1,y1,'k.', linewidth=0.1)
