Type Of Graphs Type Of Graphs Representation of the data in the form of the graph is one of the very strong tool, which is used to represent the data and then analyze from it. In the graphic mode of representation the points and lines of various kinds are used to represent the data. On the graph paper, different lines are drawn to represent the lines on the scale. The graph paper is divided into four equal quadrants, but usually the graph is represented in the first quadrant where the x and the y axis are in the positive form. When the graphs are properly constructed, these readily shows the information that may not be able to be clear with the data representation on the tables. Though the data represented on the table is more accurate, but it is very time consuming to predict the conclusions with the help of the given data. There are different Types of Graphs.

We come across different types of graphs. The graphs are basically divided into two parts, they are : Natural Scale and Ratio Scale Natural scale is further divided as Time Series and Frequency And Ratio Scale is classified as Semi Logarithmic and Logarithmic Now further if we look at the graph of the time series, we have following five types of the curves: 1. Horizontal Lines Graph 2. Component Graph 3. Silhouette Graph 4. Range or Variation Graph 5. Z- Curve Graph Now if we look at the horizontal line graph, they represent the different lines with the respect of the time change Z- Chart or Z- Curve : It is a special type of the graph which is used to represent the figures, which are represented at the regular interval of the period at the span of one year. Another type of the graph will be In the same way we say that the frequency is classified into following types of graphs: 1.
Vertical Line
2.
Histogram
3.
Polygon

Lorenz Curve
In the vertical lines curve the graph is represented in the form of the vertical lines which are drawn with the reference of the time. Histogram is another graph which is very popular and is used for charting continuous frequency distribution, without considering the data under consideration is discrete or continuous. Next we will learn about the frequency Polygon, which is the graphical representation of the curve which is superimposed on the histogram, at their mid points. So we say that the frequency polygon is the improvement over the histogram. Another graph is the frequency curve, where a free hand curve is drawn to fit into the histogram in the manner it passes through the tips of the rectangular blocks. Next we will look into the Ogive, which is the graphical representation of the cumulative frequency and thus we also call it the frequency polygon Lorenz curve is the another type of the graph which is used to represent the distribution of the wealth among the population. We also call it the cumulative percentage curve, combining percentage of the items under the review with the percentage of the factor among the items.
