A chart is a graphical technique used to represent a data set, usually as a graph showing the relationship between two or more variables. The diagram can be hand-drawn or computer drawn. In the past, mechanical or electronic plotters were sometimes used. Charts are visual representations of the relationships between variables and are very useful for people who can quickly derive understandings that cannot be derived from a list of values. You can use a scale or ruler to read the value of an unknown quantity as a function of a known quantity using a graph, but you can also use tabular data. Function graphs are used in fields such as mathematics, science, engineering, technology, and finance.
Charts can take many forms. However, there are common characteristics that give graphs the ability to extract meaning from data. Data is usually displayed graphically in graphs. This is because it is easier to guess the meaning of images than text. Therefore, the text is typically only used to annotate data. One of the most important uses of text in charts is titles. A chart title usually appears above the main chart and briefly describes what the data in the chart is related to. Dimensions of data are often represented by axes. When horizontal and vertical axes are used, they are commonly called x and y axes. Each axis has a scale that features a periodic gradient, usually accompanied by a numerical or categorical display. Each axis typically has a label along the outside or side that briefly describes the dimension represented. If the scale is numeric, the units of that scale are often added to the label in parentheses. For example, “Distance Traveled (m)” is a common x-axis label, meaning that the distance traveled in meters is related to the horizontal position of the data in the graph. A grid of lines may appear within the chart to visually align the data. Grids can be enhanced by visually emphasizing lines with regular or meaningful gradations. The highlighted lines are called major grid lines and the rest are called minor grid lines. Graph data can be displayed in a variety of formats and can include a single text label describing the datum associated with the displayed location on the graph. Data can be displayed as dots or shapes, connected or disconnected, and any combination of colors and patterns. Additionally, conclusions or points of interest can be superimposed directly on the chart to further aid in information extraction. If the data displayed in the chart contains multiple variables, the chart can have a legend (also called a key).
The legend contains a list of variables displayed on the chart and an example of what they look like. This information can be used to identify the data for each variable on the chart. You can extend the graph structure by assigning a weight to each edge of the graph. Weighted or weighted graphs are used to represent structures where the pairwise links have some numerical value. For example, if the chart represents a network of roads, the weight could represent the length of each road. Each edge can have multiple weights associated with it, such as distance (as in the previous example), travel time, or monetary cost. Such weighted graphs are commonly used to program GPS and travel planning search engines that compare flight times and costs.
