Making a bar Graph
First we need to make sure we have all the materials. A pencil, a paper, a rule,colors, what is the graph about, in this case, it of beans and lentils.

* Label the horizontal axis in a way that tells what information will be providedon the grouped data axis. Above the label, write each of the categories of your data.
* Start at the bottom with a price of 0, then mark 10, 20, 30,40, etc. until you reach the number above the highest point.
* Draw in the bars for your graph, ensuring that each bar's height corresponds to its data.You may choose to color the bars to make your graph more attractive and easier to read.
* Write a title for your graph right above it. The titleshould give a clear indication as to what the data shows.

Making a Pie Graph (Circular)
First we need the material, we will use almost the same as previousgraph, but in this graph we need a protractor.

* Draw a circle on a blank sheet of paper.
* Draw a horizontal line, or radius, from the center tothe right edge of the circle, using the ruler.
* Measure the largest angle in the data with the protractor, starting at the baseline, and mark it onthe edge of the circle. Use the ruler to draw another radius to that point. Use this new radius as a base line for your next largest angle and continue thisprocess until you get to the last data point. You will only need to measure the last angle to verify its value since both lines will already be drawn.
