I have an assignment to submit tomorrow and I've run out of graph paper. I need to plot quadratic equations. Do you know of any software using which I can plot line graphs? I'm not looking for an easy escape software in which if I write down the equation, the graph plots itself. I'm looking for a simple graphing software in which I can simply add values.
The basic software for this is Geogebra.
You can use python matplotlib. It's a python library for plotting 2D graph.
Check this link for documentation and installation instruction.
from jhplot import * f1 = F1D("x*x+x+2", -10, 10) c1 = HPlot("Example of function") c1.visible() c1.setAutoRange() c1.draw(f1)
It uses auto-range. It plots x^2+x+1 in the range -10 - 10. You can save it to EPS or PDF by appending this line:
