The terminal syntax to run the program which I call Plot is as follows. Later we will streamline this using a GUI. First we will program it to take the data files from the command line and ask for the user to provide the relevant options to construct the plot. The important quality of this program is that we want it to be generalised for as many data files as needed with a few options for plot aesthetics. Skip to the end for the complete program with GUI or read on to see how it is implemented. To use a different aspect ratio, change the 'fix aspect ratio' setting under Axes properties. The plot will be generated entirely in your own browser. I use this program regularly in my work and I hope it can prove useful for you. Quickplotter Plot beautiful graphs online - fast Welcome to Quickplotter Drag and drop or copy and paste your two-column data here to plot. In this post we will build a useful program allowing for very quick plotting of data files using Python and write a very simple Graphical User Interface (GUI) to interact with it which will look like: The problem with a lot of plotting software is they have so many options and controls that it can sometimes be time consuming to produce the type of plot you are after, especially with lots of data files. Excel, Veusz, gnuplot etc… These are all fine but something which I often need is a means to quickly plot multiple data files for comparison and have the plot look half-decent for a presentation. You can enter the radial angles n in radians, degrees. To plot the points (r n, n) in the polar coordinate system select the Polar checkbox. The point plotter plots the given point set as you type (default) in the selected Cartesian or polar coordinate system. Plotting data is a key part of any science and there are a lot of software solutions designed for this purpose, e.g. You can use numeric expressions such as 1/2 sin (/3) for point coordinates.
