Line, bar and pie charts

Data to envisage is enormous, and those presenting it frequently address bar graphs, pie charts, and line graphs to display statistics. It helps present numbers in a well-structured form by well-designed graphs or diagrams. People are becoming more visually responsive given the innovative digitalization era. Thus, they subconsciously prefer articles filled with innovative charts to interpret data easier and quicker. When representing data graphically, it is important to analyze every axis and come up with correct conclusions. SlidePeak is a service that prevents presentation from being overfilled with numerous (and not always necessary though beautiful) charts. Still, it organizes graph data and charts display in a meaningful way.

Advantages of different kinds of graphs

The advantage of charts in presentation is vivid:

  • Every data category is visualized in a frequency distribution.
  • Large data is delivered in a concise manner.
  • Key values are detected and evaluated more accessible.

Some of graphs may require extra explanation, manipulate facts, or create a false impression. In this regard, presentation design services involve experts to avoid the misunderstanding mentioned above and convey bright thoughts in the form of different types of line graphs, different kinds of graphs, or different types of pie charts.

Even complex data can be made clear with visual charts and dashboards. Why is this happening? Because most of the people in the world are visuals. And if you want most of your partners, colleagues, or customers to interact with your data, you need to turn boring tables into beautiful and dynamic graphs. Proper data visualization will bring a number of benefits to your business/project/lecture:

  • Increased speed of decision making: it becomes easier and faster to conclude by looking at a graph one with column/point much higher than all the others (than looking through several pages of statistics in Google Sheets or Excel).
  • Increased engagement of readers: beautiful bright graphics with a clear visual message will attract more attention.
  • Better data comprehension: perfect reports are understandable not only to technicians, analysts, and Data Scientists but also to the marketing director or SEO, enabling each employee to make more successful decisions.

Chart – meaning

First of all, charts are a graphical representation of data. There is a possibility to create different types of charts in Excel to represent information or statistics. Charts vary in their distinctive features and divide, e.g., into a scientific chart, statistical chart, innovative chart, etc. Though very similar, charts are frequently misplaced with graphs (Picture 1) that organize and depict the mathematical relationship between sets of data, while charts (Picture 2) display the diagrams with some data. Graphs are also divided, e.g., into a business graph, complicated graph, comparative graph, etc. SlidePeak is well-aware of this difference, so you should never hesitate to choose us and get the perfect custom presentation design.

Types of line graphs

With a line chart, the user visualizes variables, dynamics, and relationships of axes. Graphically, the image is a sequence of points connected by straight line segments into broken lines. The abscissa, as a rule, shows the temporal characteristic of the phenomenon, while the ordinate shows the value of the indicator. Using line columns in Excel, you can quickly compare sales in a company over specific periods of time, analyze the balance sheet, income and expenses, the values of some business experiment, etc.

The most common types of line (or linear) graphs include:

  • Simple line graph – relationships of one dependent and one independent variable, plotted to show the connection of, usually, time and some other factor (e.g., earnings and year to see budget holes);
  • Multiple line graph (Picture 1) – one more interactive graph that consists of 2 or more lines to display (surprise) 2 or more variables, plotted horizontally and vertically (e.g., to compare the income of different departments over one year);
  • Compound line graph – used to contain different data layers (multiple line graphs).

Types of bar graphs

Bar graph examples (Picture 2), as well as bar graph templates, are as vast on the web as any other online graph creator. However, they are quite basic for modest needs. SlidePeak helps you customize the data into charts as per your specific needs since we believe that a personalized approach is key to getting the presentation as expected. Thus, you can expect horizontal, vertical, stacked, or dot type of bar graph. Horizontal bar charts are usually used to compare a large number of indicators or visually highlight one’s clear superiority. Meanwhile, the vertical bars illustrate how the indicators have changed in different periods, e.g., the company’s annual profit over several years.

Types of pie charts

Alternative to bar charts, different types of pie charts show the structure of a dataset – what it consists of, e.g., what percentage of total sales each product category brings. They offer the proportional and percentage relationship between categories by dividing the circle into proportional segments. The length of each arc represents a proportional fraction of each category, while the whole circle represents the total of all data equal to 100%. When to use pie charts? They are perfect for visualizing the proportional data distribution.

2D pie chart and 3D pie chart (Picture 3) are two main ways to show the proportion of each value within a set. In its turn, a 2D pie chart can be simple, exploded, pie of pie, and bar of pie depending on how the variables are visualized. Nevertheless, the task of each is to display the contribution of each value in 2 dimensions. Otherwise, a 3D pie chart operates in 3 dimensions that make it more aesthetically attractive, modern, and innovative. It makes the data less readable for some users, distorting the graph, but the proper type choice will deliver data successfully.

How to choose?

The graphic data display helps convey the desired idea, support the formulated conclusion, or emphasize the emphasis. One of the difficulties that significantly slows down reporting and analytical work is finding the right chart type. Wrong use of graphs in statistics can confuse the viewers’ minds and lead to data misinterpretation. SlidePeak is here for you to get professional slides of any complexity to reach your audience of investors, customers, or students.
