It could be said that some of their ancestors were the first Europeans to discover North America in 1000 AD (see Leif Ericson). Other Normans came to Canada from countries that they had immigrated to after the Edit de Nantes had been revoked in 1685.
Can a circle graph be used to display data from a histogram? What type of data can line graphs display? Line graphs are used to display data to show how one variable (the  Responding variable) changes in response to another variable (the  Manipulated variable). Making the world better, one answer at a time.
Circle graphs/pie charts versus bar graphs When displaying statistical information, refrain from using more than one circle graph/pie chart for each figure. Figure 6 shows two circle graphs/pie charts side-by-side, where a split bar graph (two bar graphs back-to-back) would have shown the information more clearly. A user might find it difficult to compare a segment from one circle graph/pie chart to the corresponding segment of the other circle graph/pie chart.
