stock chart:A graph is a graphical representation of data, where data is represented by symbols, such as bars in a bar graph or lines in a line graph or slices in a pie chart. The chart can represent numeric data from scheduled, associative data, or some types of qualitative data structures. The term ’Diagram’ is used as a graphic representation of data that has multiple meanings: a graph of a chart type or a graphic graphic that organizes and represents a digital or qualitative data set. Decorative maps are often defined as additional information for specific purposes, such as diagrams or flight plans. Some diagrams for specific areas are sometimes called graphic charts, such as the string diagram of musical notation or the chart of records in lyric albums. Graphs are used to facilitate understanding of large amounts of data and relationships. The graph can be read more quickly than raw data is read. Graphs are used in many fields and can be drawn manually or by computer using graph software. Some types of charts are more useful in representing a given set of data than other species. For example, percentages are often represented in different groups (eg satisfied, unhappy, unsure) with a pie chart, but may be more understandable if represented by a horizontal bar graph 2. On the other hand, data that represent variable figures over a period of time (such as annual profits from 1990 to 2000) is best done using a linear chart. s.Streleche, Ukraine
