## Quiver plots using Python, matplotlib and Jupyter notebooks

A quiver plot is a type of 2D plot that shows vector lines as arrows. Quiver plots are useful in electrical engineering to visualize electrical potential and valuable in mechanical engineering to show stress gradients. In this post, we will build three quiver plots using Python, matplotlib, numpy, and Jupyter notebooks.

## Plotting a stress-strain curve with four libraries: matplotlib, pandas, altair and bokeh

After watching a great webinar about plotting with different python libraries, I wanted to see what it was like to make a stress strain curve using four different modules: pandas, matplotlib, altair and bokeh (with holoviews).

## Plotting Histograms with matplotlib and Python

Histograms are a useful type of statistics plot for engineers. A histogram is a type of bar plot that shows the frequency or number of values compared to a set of value ranges. Histogram plots can be created with Python and the plotting package matplotlib. The plt.hist() function creates …

## Statistics in Python using the statistics module

In this post, we'll look at a couple of statistics functions in Python. These statistics functions are part of the Python Standard Library in the statistics module. The four functions we'll use in this post are common in statistics:

• mean - average value
• median - middle value
• mode - most often value
• standard …

## Solving Two Equations for Two Unknowns and a Statics Problem with SymPy and Python

SymPy (http://www.sympy.org) is a Python library for symbolic math.

In symbolic math, symbols represent mathematical expressions. In a numerical calculation, the value of pi is stored as an estimate of pi, a floating point number close to 3.14.... In a symbolic math expression, the value of …
