Simple Line Plot
Simple Line Plot
A plot of several Bessel functions, with pan and zoom functionality.
Vertical Plot
Vertical Plot
Bessel plots again, but arrayed vertically (increasing X going down).
Line Drawing Tool
Line Drawing Tool
A scatter plot with a tool for drawing arbitrary line segments and subsequently moving/removing vertices. The points are drawn in data space, so if you zoom or pan the plot, the points stay fixed relative to the data.
Zooming Plot Inspector
Zooming Plot
The selection region in the upper plot can be moved (by dragging) or resized (by dragging its edges).
Colormapped Image Plot
Colormapped Image Plot
A 2D array of scalar values with a colormap applied.

The two plots have linked axes, so if you pan or zoom in either window, the other plot's window updates as well.

The right image shows the result of zooming into the plot.

By selecting a region of the color scale using right-click and drag on the color bar, certain scatter plot points are highlighted and the rest are rendered faintly. The color bar selection can be moved as a whole or resized by dragging its edges.

By selecting a region of the color scale using right-click and drag on the color bar, parts of the image plot are darkened out and parts are highlighted.

Traits UI Editor with a Plot
You can edit the equation or change the type of plot, and the plot updates in realtime. You can also pan around the plot and zoom in and out. The second image shows the result of typing "*cos(2*x)" into the equation window. The third image shows the result of zooming into the plot.
2D-Function Explorer  2D-Function Explorer  2-D Function Explorer
2-D Function Explorer 2-D Function Explorer
This is a fairly sophisticated application that allows the user to evaluate any 2-D scalar-valued function on a mesh of arbitrary dimensions. (Dialogs for configuring the function and the colormap are under the File menu.) As the user moves the mouse, horizontal and vertical cross-sections of the function are show on the plots below and to the right of the main image plot.
Audio Spectrum Analyzer
Audio Spectrum Analyzer (requires PyAudio)
This demo reads the audio signal from a microphone and plots it in the time and frequency domains. The spectrogram on the right shows the time evolution of the frequency spectrum, and slowly scrolls to the right. (Can you guess the song that generated this spectrogram?)
