LESSON TOPIC:

BUILDING DIAGRAMS

• PIE DIAGRAMS

BUILDING CHARTS

Charts used to display the dependence of the values ​​of one quantity (function) on another (argument); graphs allow you to track the dynamics of data changes.

World population

Graph of the function y=x^2

Example of a graph in spreadsheets

PIE DIAGRAMS

Pie charts used to display the values ​​(dimensions) of parts of some whole; in them, each part of the whole is represented as a sector of a circle, the angular size of which is directly proportional to the size (size) of the part.

Structure of farmland in Russia

Profit from the sale of ice cream

Example of a pie chart in spreadsheets

Histograms (bar charts) are used to compare several quantities; in them, quantities are displayed in the form of vertical or horizontal columns. The heights (lengths) of the columns correspond to the displayed values.

Area of ​​the largest countries in the world, million km 2

Example of a bar chart

DIAGRAM STRUCTURE

Data series is the set of values ​​that need to be displayed on the chart.

Charts allow you to visually compare the values ​​of one or more data series.

Sets of values ​​corresponding to each other from different series are called categories .

Diagrams are constructed in a rectangular coordinate system, where along the axis X the names of the categories are signed, and along the axis Y The values ​​of the data series are noted.

and their names

BUILDING DIAGRAMS

In spreadsheets, charts are built under the control of the Chart Wizard, which provides the following basic steps:

1) Selecting the chart type

2) Selecting the data on which the chart is based

3) Setting up chart design elements

4) Chart placement

Charts in spreadsheets remain dependent on the data on which they are built: when the data changes, corresponding changes occur in the chart automatically.

ALGORITHM FOR CONSTRUCTION OF DIAGRAMS:

• Enter data into the table.
• Select the required data range.
• Go to tab Insert | Diagrams and select the chart type.

4. Using toolbars “Designer”, “Layout”, “Format” format chart elements. Fill in the chart parameters (title, names of category axes, data axes, data labels, etc.).

5. Select where to place the diagram (on a separate sheet or an existing one).

PROGRESS OF THE LESSON

1. Learning new material

In any field of activity, there are many tasks in which initial data and results must be presented in graphical form. The ability to visually present information in the form of graphs and diagrams is an integral part of modern education. When deciding various tasks, preparing reports on various disciplines, performing creative tasks, there is often a need for a graphical representation of numerical data. The main advantage of such a presentation is clarity.

– Today in class 5 experts will help consider this topic. (Experts are prepared in advance by the teacher from among the successful students)

List of issues to be studied

• Diagrams (concept, purpose). Chart objects. Types of charts.
• Creating Charts Automatic creation diagrams (in one step).
• Chart Wizard.
• Editing diagrams.
• Editing a finished diagram.
• Editing individual diagram elements.

Diagrams (concept, purpose). Chart objects

When solving various problems and preparing reports, there is often a need for a graphical representation of numerical data. The main advantage of such a presentation is clarity.

Microsoft Excel has the ability to graphically represent data in the form of a chart. Charts are linked to the worksheet data from which they were created and change whenever the data in the worksheet changes. The diagram is an insert object embedded on one of the sheets of the workbook.

Diagram– a spreadsheet object that clearly shows the relationship of some quantities.
Purpose of the diagram: Graphical display of data for analysis and comparison.
Chart objects:
chart area– the area in which all the elements of the diagram are located;
chart area– location of axes, data rows, etc.;
legend– sample data formatting;
title– serves to explain the data presented in the diagram;
data labels (markers)– symbols (bars, dots, sectors, etc.) on a diagram depicting a single data element;
data series– a group of related data elements in a diagram, the source of which is a single row or column of a data table;
axis– a line that limits one of the sides of the chart plotting area and creates a scale for measuring and comparing data on the chart (for two-dimensional graphics– X axis, Y axis; for a three-dimensional graph, Z is the vertical axis, and the X and Y axes are located at different angles):
categories– category names correspond to labels along the X axis;
row names– usually correspond to the inscriptions along the Y axis;
tick marks- these are short segments that intersect the coordinate axes, similar to the markings of a ruler.

Chart types.

In MS Excel, you can choose from several types of charts, and each type has several varieties (types). Choosing the right chart type makes it possible to present data in the most advantageous way. MS Excel allows you to choose from 14 basic (standard) chart types and 20 additional (non-standard) chart types. Within each of the main chart types, you can select a specific subtype.
Let's look at the main ones

Histogram displays values ​​of different categories, allows you to show several data series

Ruled also displays values ​​for various categories, differs in the orientation of the Ox and Oy axes

Schedule presented in the form of data points connected by a thin line, allows you to track changes in the proposed data, show several rows of data

Pie and donut chart only one series of data can be shown. The choice of this type is determined by considerations of expediency and clarity

Area chart displays changes in series values ​​over time, as well as changes in the contribution of individual values.

Three-dimensional (volumetric) diagram include Histogram, Bar, 3-D, Pie, Surface

Why make diagrams?

• visual presentation of information
• showing correlations of values ​​or dynamics of changes in tabular data

This is needed for:

Chart Basis A table is used as the basis for creating a chart. The rectangular table structure allows us to construct a diagram based on a rectangular coordinate system. The data elements (individual numbers) plotted on the chart are combined into data series ( a group of consecutive cells located in a row or column of a table).

A diagram is a compositional object consisting of the following main elements:

Chart drawing area with grid lines

Signature for the Y axis

Coordinate axis

X-axis caption

Heading

Data Signatures

Legend - notation system

Basic elements of a diagram

Types of charts 1. Pie charts (they are used when the values ​​of a data series describe the distribution of some quantity or contribute to a whole).

There are several types of charts. They are different appearance, purpose and number of valid data series. Here are some of them:

2. Bar or column charts - histograms (this form is convenient for comparing values; one chart can display several data series).

3. Graphs (serve to display the dependence of the value of a function on its argument; time, distance, or another variable can be used as an argument).

Types of charts Any chart represents one of the three main categories presented above. There are different options for their design. In three-dimensional design, data elements are represented by images of three-dimensional figures (parallelepipeds, cylinders, cones, pyramids) to improve clarity.

Building a chart

• When choosing the type of graphical representation of data (graph, histogram, chart of one type or another), be guided by what kind of information you need to display. If you want to identify changes in a parameter over time or a relationship between two quantities, you should create a graph. It is customary to use a pie chart to display shares or percentages. Comparative analysis It is convenient to present data in the form of a histogram or bar chart.

Building a chart Procedure:

• Select the cells containing the data to plot the chart.
• In the Charts group, on the Insert tab, do one of the following:
• Select the chart type and then the chart subtype you want to use.
3. By default, the diagram is placed on the sheet as embedded. If it needs to be placed on a separate sheet, then:
• On the Design tab, in the Location group, click Move chart.

Building a chart 4. Click on the chart to open the Chart Tools panel, which contains additional Design, Layout, and Format tabs. With which you can choose a ready-made layout and style for the diagram. 5. Formatt the chart.
