Graphing RockSim Data To Compare Simulations

One limitation with RockSim is that it can’t graph out data from two simulations (or more) so that they can be compared. In this article, we’ll show you how to export the simulation data and then to plot it out to a graph in a spreadsheet program. This way you’ll be able to compare multiple simulations.

Exporting the data from RockSim is rather easy. The challenging part is combining it in a spreadsheet to create the graphs.

For our example, we will be plotting a graph in Apple's Numbers software that compares launch angles of an Apogee Zephyr flying on an Aerotech G67. More specifically, we want to be able to compare the altitude achieved and how far away the rocket is likely to land when launched at various launch angles.

The article specifically covers plotting a graph in Apple's Numbers software for the Macintosh OS. We also have a couple of video tutorials that cover this same topic, but for different software. For combining graphs in Microsoft Excel, see Tutorial Video #20. For Google Sheets instructions, see https://youtu.be/nI5kKz5HDck

Read the rest of this week's article, either on a downloadable PDF for printing out, or on our website (great for viewing on your phone)!

Estes Der Big Red Max

The Der Big Red Max uses 29mm motors insidde a 3" diameter airframe, making this the highest flying Der Red Max in the family.

This kit contains all laser-cut balsa fins and cardstock centering rings, a (very unique) heavy-duty plastic parachute, thick-wall tube and an unrivaled sticker-type decal sheet and artistic scheme. If you are looking for a visually unique flyer, or a fan of the lore and legend around the Red Baron from WW1, then this rocket is an easy choice. It's a big der.

"Every time I have called or contacted Apogee I have been very please with the service and assistance. It doesn't get any better than Apogee. #1 in my book."

-- Louis Santoni

Write a Testimonial!

We're looking for someone to write a definitive guide to selecting igniters, controllers and batteries for rockets. We'd love to have a newsletter article on that topic, because we get lots of inquiries about it. Is that you? Do you know how many e-matches can be set off in a cluster by a 3.7v 400 mAh battery? See our Newsletter Guidelines on how to submit an article on this topic and get paid up to $350 for your time.

I need help with generating the bi-weekly newsletter articles since it takes a lot of effort to put them together. And I'm willing to pay big bucks for your help.

So ask yourself, are you looking to earn some extra money?

I'm now actively seeking writers for articles to appear in this newsletter. And I want unique and cutting-edge articles because that is what you want to read, right? I realize this, so to get articles from outside writers that have the same level of quality, I'm going to have to pay a lot of cash to make it worth it for them. So I've come up with a compensation package where I'll pay up to $350 for good how-to articles.

Are you a writer, and does that interest you? That is a lot of cash! Far more than you'll get by writing for other magazines. And with over 23,000 worldwide subscribers, if you write for the Peak-of-Flight Newsletter, you'll gain a lot of notoriety. Writing for the Peak-of-Flight Newsletter is a great way to show off your rocketry projects and your technical expertise, at the same time as helping out other rocketeers. Imagine how great you'll feel knowing that you made a difference to the hobby.

If you're interested in writing, see the guidelines on our site.
