How can I trace curves in python programming. Does It give a plot? I know how to plot, but I want to trace the plot by another point.
Your question is not completely clear to me. Are you looking for a way to interpolate between different points that define your curve? Or do you wish to fit the curve to some function? Please try to explain in a bit more detail what you need.
Ok. Suppose I want to plot sinx using python, by plot command Python will plot it. But what I am trying to say is we have to show as x changes sin(x) also change using two points, I hope you had followed.>>>
Is this what you are looking for?
============================================
#!/usr/bin/env python
# import needed modules
import os, numpy, matplotlib, matplotlib.pyplot
# create the data arrays
x = numpy.linspace(-numpy.pi, numpy.pi, 101)
y = numpy.sin(x)
# settings
plotfilename = 'plot.png'
# make the plot
fig = matplotlib.pyplot.figure()
ax = fig.add_subplot(1,1,1)
ax.plot(x,y,marker=None,color='blue')
# annotate the plot
ax.set_title('a simple 2d plot')
ax.set_xlabel('x')
ax.set_ylabel('sin(x)')
# save the plot
fig.savefig(plotfilename)
===============================================
still I don't understand what you are trying to say about these 2 points.
Hi
PyPlot doesn't have any built-in support for this, but you can easily implement some basic curve-fitting yourself.

Besides PyPlot you can use another awesome libraries like matplotlib and seaborn.
