Bar Graph

A bar graph is also called a bar chart and consists of bars that are separated from each other. It either uses horizontal or vertical bars to show comparisons among categories. The bars can be rectangles, or they can be rectangular boxes (used in three-dimensional plots). One axis of the graph represents the specific categories being compared, and the other axis shows a discrete value. In this graph, the length of the bar for each category is proportional to the number or percent of individuals...

This protocol details the use of Hopkinson pressure bars to measure reflected blast loading from near-field explosive events. It is capable of interpolating a pressure-time history at any point on a reflective boundary and as such can be used to fully characterize the spatial and temporal variations in loading produced.

Multiple Bar Graph

As the name suggests, a multiple bar graph is the same as a bar graph but has multiple bars to depict relationships between different data values. One can include as many parameters as possible. However, each parameter must have the same unit of measurement. Each bar or column in the multiple bar graph represents a data value. These graphs are used primarily in interrelating two or more sets of data. The categories of different kinds of data are listed along the horizontal or x-axis, whereas...

In vivo mammalian models of critical-sized bone defects are essential for researchers studying healing mechanisms and orthopedic therapies. Here, we introduce a protocol for the creation of reproducible, segmental, femoral defects in rats stabilized using external fixation.
FAQs
Mechanical stability comes from matching the bar’s geometry to the subject or specimen and coupling it to a compatible holder or frame. This arrangement distributes applied forces rather than concentrating them at one point, while preserving access to the brain and nearby anatomy. The result is more consistent positioning, which helps limit motion-related variability during neuroscience measurements.
A custom configuration matters because subject shape, fixation interfaces, and experimental access requirements may differ across preparations. The bar must be shaped or arranged to fit the relevant anatomy and connect appropriately with supporting hardware. Poor alignment or an unsuitable interface could compromise positioning consistency or obstruct the region needed for imaging, electrophysiology, or other measurements.
Reducing motion-related variability improves the consistency of measurements collected from a preparation. If positioning changes during an experiment, observed differences may reflect mechanical movement rather than the neural or behavioral phenomenon under study. A Custom Fixation Bar addresses this source of variation by supporting repeatable alignment, thereby strengthening data quality and making comparisons across measurements more reliable.
A basic workflow begins by determining the subject or specimen geometry and the anatomical access required for the experiment. The bar is then shaped or configured accordingly, attached to a compatible holder or frame, and positioned so forces are distributed while the brain and surrounding anatomy remain accessible. Researchers can then assess whether alignment and positioning remain stable during measurement.
This approach can support imaging, electrophysiology, behavioral experiments, and other measurements that require stable alignment. Its value differs with the measurement, but the common benefit is mechanical consistency during data collection. By limiting motion-related variation, the support can help researchers obtain more reliable measurements when precise positioning affects the quality or interpretability of the experiment.
In longitudinal work, mechanical consistency is especially important because researchers must interpret measurements collected over time. A purpose-built bar can improve the reliability of positioning across the study, reducing one source of variation between measurements. This supports more dependable comparisons over time and can strengthen the reproducibility of experiments that follow the same subject or preparation.
