Projector mode

Projector mode switches Separatrix to a light theme with larger type and thicker lines, so a plot reads from the back of a lecture hall. The dark theme is the chalkboard theme, and it is the default.

Switch it on

Click the projector button at the right end of the top bar. Its tooltip reads "Projector mode (light theme, larger type, thicker lines)". Click it again, now a moon, to go back to the dark chalkboard theme.

Separatrix remembers your choice on this computer, so it opens in the theme you used last.

What changes

• The background turns light and the ink dark.
• All text is 15% larger.
• Plot lines are 1.75 times as thick.
• The panels keep their layout. The View control's short labels (Phase, Series, Section, 3D, λ, Branch) still fit a window 1,024 px wide.

Nothing about the maths changes. The trajectories, fixed points and numbers are the same in both themes.

Export for slides

Exports don't follow the screen's theme. The export dialog's Colors setting chooses Projector, the default, or Dark for each figure. See Export figures and data.

Tips for teaching

• Open your projects before the lecture, so they are under Recent in the gallery.
• Drag a parameter slider slowly. Every view updates as you drag.
• To point at a fixed point without the mouse, focus the plot and press F. Each press selects the next fixed point. The other keys are in Keyboard shortcuts.
