- Using Microsoft Excel to Make A Graph Plotting an X-Y Data Set. Suppose we want to plot the volume of hydrochloric acid used vs. The moles of magnesium. The first step in creating a graph using Microsoft Excel is entering the data. The data should be in two adjacent columns with the x data in the left column.
- Plot (X,Y) creates a 2-D line plot of the data in Y versus the corresponding values in X. If X and Y are both vectors, then they must have equal length. The plot function plots Y versus X. If X and Y are both matrices, then they must have equal size.
Graph Individual (x,y) Points - powered by WebMath. The most basic plotting skill it to be able to plot x,y points. This page will help you to do that.
Here is the graphics program that can display graph by taking two sets of Y values and X values are common for the both.
