As a tester, I’ve always had a few data visualization tools in my toolbox. I’ve mostly used Microsoft Excel regular and pivot charts, and gnuplot. Now I’ve found a nice plotting program for my mac when I have some raw data I’d like to see in a chart.
I’ve been playing with Plot to display a chart of weights for our CCI puppies. I like it over gnuplot 4.0 + aquaterm because I figured out how to change line colors for each column of data, and it’s easier to zoom. Here’s the sample output (click on image to view full-size):
and the zoomed view:
I use a short script of Plot macrto commands to import the data from a flat text file and set the color options.
From the “picture is worth a thousand words” school . . .
I created two screencasts to demonstrate how I updated the SHAPE forum while I was guest-moderator. I thought they might be useful to the next moderator, and I’ve wanted to try my hand at creating screencasts.
Here’s what I used on my mac:
- MenuShade to dim the menubar
- Mousepose’ to highlight the mouse position
- Backdrop to cover the background
- USB Headset with noise-canceling microphone
I did a little bit of planning, rehearsal of some of the trickier bits, and I think the screencasts came out generally ok. I also think I’ll get better at them the more I do them.
But I’m much better at doing tasks like this if I have a real-world problem to solve.
So, does anyone want a particular screencast from me?
