Plot is a scientific 2D plotting program.

This project started in 1993 with SciPlot on NeXTStep and continues with "Plot" for OS X till 2007.

Plot is designed for everyday plotting, it is easy to use, it creates high quality plots, and it allows easy and powerful manipulations and calculations of data.

Basically Plot allows to work with multiple documents where every document consists of one or more XY data sets (called buffer in Plot).

There is also the possibility to add subviews (plots inside plots) to your document. A subview is completely independent with its own data buffers, graphic attributes etc.

Data can be imported from text or binary files, directly from a MySQL database, with a Perl based import filter. It is also possible to import data by using copy&paste or drag&drop from other programs.

Plot supports many plotting styles like lines, symbols, grids, bars, filled areas, sticks, dots, histograms, error bars, automatic legend, text and graphic objects, etc.

Plot can import images from other programs with copy&paste or drag&drop.

Plot has many data manipulation methods integrated: smooth, spline interpolation, differentiation, integration, normalising, moving, data calculations, function generator, curve fitting, etc.

Plot has also a built in macro language for automating complex tasks.

Missing Something

I was able to create a legend, label and personalize my axis, and scale the perameters, but I see no actual way to plot anything. Theres a screen with what looks like a spreadsheet but no way to enter antything, nothing is clear about how you would go about it, there aren’t even any videos that I could find for this software that aren’t just videos of people using similarly titled programs that actually work and make me wish I had a PC again. I tried for like half an hour literally going through every key command and tab. I’m not a grandpa, I’m excel certified and I have literally the most simple task possible when it comes to graphing. The interface is trash, theres no view tab which likely would solve many of this programs problems, and it honestly feels like less of a waste of time to write about this application than it does to actually use it.

The downfall of a great program

This program “plot” used to be one of the best 2D graphics programs out there coming from the next-step era. It gave the user excellent control over
the details of the plot and the fitting capability was quite good. plot stopped working and plot2 was born. It could do almost nothing when it was first released - but - O.K. - it could be slowly improved. But it nerver was.
After many updates plot2 finally reached the state of ultimate dysfunctionality. Forget data fitting - that never worked with plot 2.0 - I’d be happy if it could
actually open the data files I once plotted with “plot”. My recommendation to whoever develops this software is to remove it asap from the App Store, make it work and then make it available again. There are good commercial alternatives such as “Kaleidagraph” and free alternatives such as “gnuplot”, infinitely more capable than plot 2.0.

Great app that has saved by bacon.

I’ve used Plot 1.x several times over the years to deal with large dataset that Excel and similar programs could not handle. Though I’ve switched over to using R and Python for handling such datasets, I still use Plot to quickly sort through data and get a rough idea of how I would like to display this data for reporting purposes.

I’m very pleased to see development continue on this app and look forward to exploring its new look and features. Just on past experience alone this app gets five stars from me!
