I suggest a scatter-graph of line graph, with time as the independent axis.
A bar graph would be best to compare how salt and baking soda dissolve in water. You can measure and compare the amount of each substance dissolved over time and represent this data in a clear and visual way using a bar graph.
A line graph.
Line Graph.
A double line graph is used to compare two sets of data. Usually the data is taken over a period of time and compared at set intervals.
Bar graph for amounts. Histogram for amounts over a certain amount of time.
A line graph is the best choice for graphing your data when you're showing quantitative data (numbers) over time. A bar graph is best when you're showing qualitative data and quantitative data at the same time. A line graph could be: Laps run in a minute. A bar graph could be: Laps run by Legolas, Gimli, Hermione, and Harry in 5 minutes.
line graph
you can see the change over time
A line graph is used to show data over time.
A line graph to compare temperatures over time. A bar graph to compare temperatures at different locations (cities), for example.
a line graph
if you are graphing a change over time, a line graph. if you are comparing data, it's a bar graph.
