Study Notes
Chart Basics
- A chart is a visual representation of numerical data.
- Effective charts display data clearly, making trends and patterns easy to understand.
- Charts help people make better decisions by summarizing data.
- Computer-related job data is commonly displayed in rows and columns in charts.
Column Charts
- A column chart displays data vertically; each data series forms a column.
- The height of the column represents the data value.
- Charts can show estimated numbers of computer-related jobs by job title in 2020.
Bar Charts
- Bar charts use horizontal bars to compare data across categories.
- The width of the bar indicates the data value.
- Data series can be clustered or stacked.
- Charts can show computer-related jobs in 2010 and 2020, making comparisons between years easy.
Line Charts
- Line charts use lines to connect data points, visualizing trends over a period.
- Different lines represent different data series, facilitating comparisons.
- X-axis (Category axis) usually represents time.
- Y-axis (Value axis) represents the value of the data points.
- Charts can show trends in majors over the years (e.g., Arts, Business, Education, Tech & Computing).
Pie Charts
- Pie charts represent a single data series using sectors with proportional areas.
- Each sector's area reflects the portion of the whole represented by the category.
- A legend identifies each sector with a label and color.
- Data labels (e.g., percentages) might be on each sector.
- Charts can illustrate the percentage of new jobs in 2020 by job title.
Chart Elements
- Chart elements are components that enhance chart clarity.
- Axes (X and Y-axes and their titles/labels) help with understanding.
- Chart titles summarize the purpose of the chart.
- Data labels provide exact values or names for data points.
- Data tables provide the raw data source, helpful if chart is on a separate sheet.
Create Chart Filters
- Chart filters control which data series and categories are visible in a chart.
- Filters allow selecting and customizing data displayed in charts, like removing series or editing ranges.
Creating Sparklines
- Sparklines are miniature charts displayed in a single cell.
- They present condensed data visualizations (like a line, column, or win/loss graphic).
- Sparklines do not include chart elements like chart titles, making charts compact.
