title: Pyplot plot function
body: <p>Given below is the code for plotting points using pyplot.</p>
  
  <pre><code>x1=300+p[k]*math.cos(val[thetaval])
  y1=300+p[k]*math.sin(val[thetaval])
  plt.plot(x1,y1,'k.')
  </code></pre>
  
  <p>The plotting is working fine, the problem is, if I want to plot it as a point I am specifying the dot in <code>'k.'</code> inside the plot function. The output is something like:</p>

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