A bar graph shows data in columns, while a bar chart is a technical analysis tool that displays the open, high, low, and close prices for a particular security during a specific time period (such ...

In this post we show you how to create a Bar Graph or Column Chart in Excel. Bar graphs could be both 2-D or 3-D depending on the editor you use.

There are a total of fourteen IN-13 bar graph tubes that map out the audio spectrum. The build uses purely hardware for the display; no microcontroller processing, or dedicated VU-meter chips were ...

A bar graph is a two- or three-dimensional representation of data. Bar graphs — also known as bar charts or column charts — are one of the most common and straightforward ways to visualize ...

The takeaway: every bar graph needs a zero on its scale. If you see one without a zero, be careful. In a future post I'll discuss whether line graphs and other graphs also need a zero on their scales.

In a bar graph, however, the horizontal axis can take on a slightly different role. For example, if you are comparing the populations from three different years in a bar graph, the horizontal axis ...

A bar-graph display provides an easily interpreted graphical indicator that allows comparison with its full-scale value, but a conventional microcontroller-based design uses at least one eight-line ...
