This was further validated by a colleague who thought it would be problematic.
The more I thought about this, the less my initial idea of building a shapefile for Graph Builder seemed to be a good fit.
When I was done with my research, I had discovered that I need to somehow build a group of circles with specific radii, and I needed those radii to match up with a user-provided set of data. ( Again – no problem, particularly because a kind professor had posted their lecture notes on their website, which included the required equations to relate the physical quantities to the radii of the circles.) Further, it’s pretty common for people who work with these things to convert the data from the Polar coordinate system (data points plotted in radius and angle) to a Cartesian system (data points plotted in x and y) for easier plotting. ( That made sense to me.) It also turns out that they are made of overlapping circles and circle arcs where the radius of a given circle is related to measured physical quantities. It’s pretty interesting reading, but to be honest, the nitty-gritty details really don’t matter for this discussion.Īt a high level, a Smith Chart is a flavor of polar coordinate plot used for electrical engineering. So, suitably chastised, I began with figuring out what these plots were. That’s for someone else.” Apparently, life had other ideas. I took one look at the Community question and thought, “Nope. To be honest, I’d seen the questions he mentioned in the Community. That’s exactly what I was thinking when I saw this question. (No promises, but I’d need the data to cross check if I did it correctly.) I might be able to create a shapefile that would fit the bill of overlaying the grid on top of the data. Seems like something JMP could do…Ĭan you share the data you’ve used to make that contour plot? Smith chart template – is there a way to plot two data fields (real & imaginary coordinate values) onto a Smith chart?įound an example of contour plot on Google. We can live with converting to rectangular coordinates for now, but figured it was worth asking if you’ve seen it before or knew someone at JMP who might be able to help. Quick question – do you know if there exists an add-on or a script for JMP for plotting polar coordinate types of graphs? Namely looking to do contour plots on a Smith Plot, example pasted below, for some RF impedance analysis. …And for the record, Nick, this was not a “quick question"!! D The Question Mike , So, without further qualification, below is an example of a really good curveball from another colleague from New York state that I thought would be fun to share. In short, this is one of those cases where the journey is significantly more instructive than the result. And, second, I’m going to illustrate the thought process I go through when solving problems using JMP.

First, it’s an example of how to repurpose graph customizations to reach a goal. I wanted to share this particular one for a couple of reasons. Other times, the questions are just unexpected, challenging problems. These applications are generally clever, and many times bring home how using data isn’t just for business or technical problems. Each planet can offer insight into your individual character and clarity about your soul's avenues for growth and personal evolution.įor information on how to read your birth chart, check out our article How to Read Your Astrology Chart.The Engineering Mailbag Episode 3: John Jacob Jingleheimer…Smith Charts!Įvery now and again we systems engineers run into interesting questions that would fall somewhat outside the typical range of JMP usage. For example, to calculate your Sun sign we look at which zodiac constellation the Sun was sitting in at the time of your birth.Īstrologers interpret this map by looking at the interplay of all your astrological elements and based on the archetypes that each of the signs represent. Your planets are plotted onto the wheel to see which sign they fall into to. Each section is named after the famous constellations or zodiac signs that we are all familiar with (i.e Aries, Leo, Gemini, …). Visually a chart is a 360 degree wheel divided into 12 sections. The location, date, and time of your birth is all that is needed to calculate your birth chart. Every individual’s birth chart (also know as a natal chart) is completely unique. Think of it like a map that provides a snapshot of all the planetary coordinates at the exact time of your birth.
