What graph should I use to compare prices?

Bar charts are good for comparisons, while line charts work better for trends. Scatter plot charts are good for relationships and distributions, but pie charts should be used only for simple compositions — never for comparisons or distributions.

Which graph is best used to show the increasing and decreasing temperature?

Line Graph

Line graphs are the best type of graph to use when you are displaying a change in something over a continuous range. For example, you could use a line graph to display a change in temperature over time. Time is a continuous variable because it can have any value between two given measurements.

Which chart types is best to show trends increases and decreases levels and costs during a continuous period of time?

Line Chart – Your Best Chart to Show Trends Over Time. Line charts are the best visual presentation for emphasizing change over time. Consider two variables, one on the vertical axis and the second on the horizontal axis.

Which type graph is best for displaying the change in values over time?

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. . . .
