# Bar Chart Maker

Instructions: The following graphical tool creates a bar graph based on the data you provide in the boxes below.

All you have to do is type your data and also name of the categories, or just paste it from Excel. The tool will deliver a bar graph that corresponds to the data entered.

Type the title (optional)
Name of X variable (optional)
Name of Y variable (optional)

A chart or bar graph is a type of graphical display suited to exhibit the relative relation of several categories and values associated to them. These values could be frequencies, but it is not always the case (could be other type of counts).

There are other more specialized charts that take the form of a bar chart, such as the histogram of frequencies, where the vertical values actually correspond to frequencies.

## How to use this online bar graph maker

This online bar graph generator will provide you will all the tools you need to make a quick and nice looking bar chart. All you need to do is to type your data or simply paste it from Excel, and click on "Graph it".

The key components of a bar chart will be the categories and the frequencies associated to each of those categories, which you will type in in the form above. This graphing tool will use the data you provide to create a nicely formatted bar graph.

One cool thing this grapher does is that it allows you provide a custom title as well as adding custom graph labels.

## How do you create a bar graph

Creating a bar graph is simple: All you need to do is to place the categories on the x-axis, and the frequencies on the y-axis, and assign a bar to each of the categories, where the height of the bar is simply the frequency associated to that specific category.

Then, you need to dispose this information graphically. This could be done by hand, but to make things a lot neater, you should probably use a specialized bar graph creator, drawn and deliverable as a digital file if possible.

No matter how good you are at drawing, a calculator that can serve as a graph maker will likely output a chart that will look neater, as a calculator will use geometrically exact measures at drawing elements.

### How do you do a bar graph with error bars?

A bar graph is a great tool to assess differences in the frequency distribution of several groups, but often times, it does not give enough information about the variability within those bars, when appropriate.

A bar graph generator with error bars will provide you exactly with that, with a main bar and smaller error bars to depict variability of the main frequency. That is a potential use for error bars in a bar chart.

### Stacked bar graph maker

A stacked bar graph will stack up more than one category per bar, and hence its name. Our calculator does not create stacked bar graphs, for that, one good alternative is to use Excel.

### Other related graph generators

There is a large diversity of charts you may be interested in, and all in all, they serve a similar purpose which is to depict distributional properties of a variable.

Other possible graph creators you can use are our Pareto chart maker, line chart maker, pie chart maker or histogram maker.
