chaco.examples.demo.basic.scatter module

Scatter plot with panning and zooming

Shows a scatter plot of a set of random points, with basic Chaco panning and zooming.

Interacting with the plot:

  • Left-mouse-drag pans the plot.

  • Mouse wheel up and down zooms the plot in and out.

  • Pressing “z” brings up the Zoom Box, and you can click-drag a rectangular region to zoom. If you use a sequence of zoom boxes, pressing alt-left-arrow and alt-right-arrow moves you forwards and backwards through the “zoom history”.
