Bar charts are most useful for comparing discrete categories or groups of data. They are effective in displaying the distribution or relationship between different variables in a visually clear and concise manner.
The main ones you need to know on a basic level are categoric and continuous. Categoric ones you will display on a bar chart as they are fixed units. Eg plastic or a range of no.s lumped in togetherContinuous variables are shown on a line graph as they do not have a differentiating X value (category) into which you can separate themHope this helps a bitThe three different kids of science variables are independent, dependent, and controlled.a variable is something you change and there's a independent variable and a dependent variablein an experiment there are three variables: responding, controlled, and manipulated. manipulated is the variable that is changed by the guy who does the experiment. responding is the variable that changes due to the manipulated variable. the controlled variable is the variable that is controlled throughout the experiment. anyway im not sure if this is what you wanted to know
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.
A categoric chart - pie or bar. For example, answers to what is your favourite fruit?
The bar chart is a great tool to use as a visual for presentations or reports. The limitation of bar charts is that it is best used when presenting only two to three variables. It is also best used only when there is discrete data to present.

Line charts, column charts, area charts, bar charts, stock charts, xy (scatter) charts and bubble charts.

Dual bar charts, or double bar graphs, are just like regular bar graphs, except there are two bars for each value on the x-axis.
Bar charts should not be drawn in the scale to real life. Each bar should be in scale to every other bar, allowing proper interpretation.
Bar charts, pie charts and line charts.
Your question isn't valid because you need an experimental procedure in place before you determine the variables.
