chaco.examples.demo.scales_test module¶
Draws several overlapping line plots.
Left-drag pans the plot.
Mousewheel 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 control-y and control-z (Meta-y and Meta-z on Mac) moves you forwards and backwards through the “zoom history”.
Right-click and dragging on the legend allows you to reposition the legend.
Double-clicking on line or scatter plots brings up a traits editor for the plot.
