plot line graph

Let us learn about plot line graph

plot line graph is called as a Cartesian co ordinate’s plane. Plot line graph contains a couple of vertical lines is said to be as coordinate axes. The horizontal axis value is the x axis value & the vertical axis y axis value. The points of intersection of those 2 axes values are said to be the origin of coordinate graphing pictures. Moreover, point to a right of the origin on the x axis value & above the origin on the y axis represents positive real numbers. The points to the left of the origin value on the x axis or below the origin on the y axis represent negative real numbers. In this blog we shall discuss about plot a line graph.

Plot line graph are more popular than all other graphs combined because their visual features reveal data trends clearly and they are easy to create. Particularly, a line graph is a set of quantitative data, plotted in an x-y coordinate system, that are connected together by lines. The data used to create a line graph must be composed of pairs of observations. The best example, a time series is composed of pairs of values: measurements or statistics of some type, & the time periods during which those measurements were taken or for which those statistics were estimated.

Merits of using line graphs include:

  • Plot line graph are good at showing specific values of data, meaning that given one variable the other can easily be determined.
  • Plot line graph show trends in data clearly, meaning that they visibly show how one variable is affected by the other as it decreases or increases
  • Plot line graph enable the viewer to make predictions about the results of data not yet recorded.

In our next blog we shall learn about Linear programming problems I hope the above explanation was useful.Keep reading and leave your comments.
