For an ordinary bar graph you need two variables, the dependent variable being numerical. You need at least two observations - unless you want a bar graph that serves no purpose.
You could have more than one dependent variables for a stacked or grouped bar graph.
Line graphs and Bar graphs
Yes - in the usual orientation of bar graphs. However, bar graphs can be horizontal.
All graphs need labels or data on both of the axis to be of use. So all graphs require a "key"
line graphs, bar graphs,and circle
bar graphs use bars and pictographs use pictures
Some common types of graphs used in science include line graphs to show trends over time, bar graphs to compare different categories, scatter plots to display relationships between variables, and pie charts to represent parts of a whole. Choosing the appropriate graph depends on the data being presented and the message that needs to be conveyed.
bar graphs are for measuring points of data.
circle graphs add up to 100% , bar and line graphs don't
well...not sure if you know this but bar graphs already ARE bar graphs, the good news is you don't have to transform them... so half your work is already done XD!
Line graphs and Bar graphs
You use a bar graph when you need to show comparisons between items. (categories)
Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.
Bar graphs and line graphs.
Yes - in the usual orientation of bar graphs. However, bar graphs can be horizontal.
Bar graphs show an '''amount''' of data. Line graphs show data '''over time.''' Pie graphs show a '''percentage''' in the data.
