The blade is connected to a vernier scale, which provides a higher degree of measurement precision. It has a rotatable blade or limb that can be adjusted to any angle. The universal bevel protractor has a circular base with a graduated scale that ranges from 0 to 360 degrees. It is a flexible tool for measuring angles inside and outside a structure as well as the inclination of a surface. Chart 5.4.5 would certainly be easier to read as a bar chart.The universal bevel protractor is a precision tool for taking angle measurements. If there are more than five or six categories, consider using another type of graph to display the information. However, there are too many items in the pie chart to quickly give a clear picture of the distribution of movie genres. In the Chart 5.4.5 below, the legend is formatted properly and the percentages are included for each of the pie segments. However, the proportions are not indicated in the labels so it’s not possible to know precisely what the proportions are. The pie chart shows the proportions for the categories: dog, cat, bird, fish and other. The user can still develop a picture of what is being said about the type of pets sold by this store, but the message is not as clear as it would have been had the parts of the pie been labelled. It is more difficult to understand the message behind Chart 5.4.4 because there are no percentage figures given for each slice of the pie. We can easily tell what the message is by simply looking at the accompanying percentages. The pie chart above conveys a clear message to the user-that 74% of all students in the World Religions class celebrate Easter. The information is grouped by Celebrate Easter (appearing as row headers), Percentage (%) (appearing as column headers). This table displays the results of Data table for Chart 5.4.3. This way, users do not have to constantly look back at the legend in order to identify what category each colour represents. If there are few categories, the percentage and the category label should be indicated beside their corresponding segments like in Chart 5.4.3. Labelling the segments with percentage values often makes it easier to tell quickly which segment is bigger. The final category need not be measured as its radius is already in position.
This point is clearly emphasized by its visual separation from the rest of the pie. The pie chart above clearly shows that 90% of all students and faculty members at Avenue High School do not want to have a uniform dress code and that only 10% of the school population would like to have one. The information is grouped by Response (appearing as row headers), Percentage (%) (appearing as column headers). This table displays the results of Data table for Chart 5.4.1.
