There aredifferent type of graphs , but most commanly graph is
1) Histogram
2) pie chart
3) bar diagram (graphs)
4) line graphs
1) Histogram- this types of graph is more suited for frequency distributions with contineous classes in this upper limit of class is the lower limit of the following distribution. The magnitude of the class intrvals are plotted along the abcissa and their frequency along the chosen scale.The number of rectangle will be equal to the number of classes.in this digram discrete frequency distribution can alos be drawn by making an assumption. Time series are depicted through a graph taking on the X-axix and the variable under consideration on the y axix
2) pie chart A pie chart is a circle divided into component sectors according to the break up of components given in percenrage if each component is represented by a circle large figurs would need large circle but the percentage remove this difficulty .in a pie chart only one circle represent all component. circle represets 360 degree angle is divided in proportion to the percentage. a pie chart is good to represent the component break up of a thing or commodity.
3) Bar diagram Bars of equal width make the comparison simpl. for any comparison the advantage of bar diagram they are most prominent and attractive. ghe bars are filled with dashes dots and colours the shape of the two types of diagram .
4) line graphs A variable is taken along the x axis and the other along y axis the variate values are suitably along the axes and all distance are measured from the origin if the smallest value in the bivariate data are frequency distribution is at a distance from zero the origin is shifted suitably to a value other than zero the indepedent variable should be taken on x axis and the dependent variable on y axis.
