chart navigation
Mouse gestures, axis strips, reference lines, keyboard shortcuts, and interaction rules.
two interaction models
skewbot charts divide into two interaction models:
- Snapshot charts (curve, term): Have no time axis. Built-in plot gestures operate manually. The mouse wheel zooms value axes, and right-drag opens a rubber-band zoom box.
- Time-series charts (flex, tilt, shear, liquidity, fixed delta vols): The mouse wheel zooms the time axis. Ctrl/Cmd targets the metric axis. Shift targets the spot axis.
mouse: time-series charts
| Gesture | Action |
|---|---|
| Scroll wheel over plot | Zooms time around the cursor timestamp (clamped between 0.1x and 10x) |
| Ctrl/Cmd + scroll wheel or pinch | Scales the metric axis only |
| Shift + scroll wheel | Scales the spot price axis only |
| Drag left or right | Pans through time |
| Drag up or down | Moves the metric series and spot line together |
| Ctrl/Cmd + vertical drag | Moves only the metric series. Horizontal movement still pans time |
| Shift + vertical drag | Moves only the spot price series. Horizontal movement still pans time |
| Right-click | Adds or removes a horizontal reference line |
| Double left-click anywhere in pane | Resets all scales and resumes following live data |
| Double right-click over plot | Opens the horizontal line settings |
| Hover | Displays crosshairs, readout pills, and a synchronized vertical time marker across all panes |
[!IMPORTANT] Panning or zooming time disables live auto-follow. The series continues to update in the background. Double left-click anywhere in the pane or select reset view to re-enable live auto-follow.
the axis strips (time-series charts only)
The narrow vertical strips beside each time-series plot control axis scaling. The left strip controls the metric axis. The right strip controls the spot price axis.
| Gesture | Action |
|---|---|
| Scroll wheel over a strip | Stretches or compresses that axis alone (0.1x to 10x) |
| Drag a strip vertically | Slides that axis alone, leaving the other axis in place |
Each strip prints its axis name at the bottom edge. Curve and Term print IV at the bottom of their left Y-axis. Point to reset view in the identity row to see the double-click shortcut.
mouse: snapshot charts (curve, term)
| Gesture | Action |
|---|---|
| Scroll wheel over plot | Zooms both axes together (anchored on the center of the current view) |
| Scroll wheel over bottom strip | Zooms the horizontal axis only |
| Scroll wheel over left strip | Zooms the vertical axis only |
| Shift + scroll wheel | Zooms the horizontal axis only |
| Ctrl + scroll wheel (or Mac pinch / ⌘ + wheel) | Zooms the vertical axis only |
| Left-drag / Middle-drag | Pans both axes across the canvas |
| Right-drag | Rubber-band zoom to the drawn rectangle (minimum 16 points required) |
| Right-click | Adds or removes a horizontal reference line |
| Double left-click empty space | Resets both axes to auto-fit data |
| Double right-click over plot | Opens the horizontal line settings |
| Hover | Displays crosshair rulers and numerical readout snapping to nearby series |
[!NOTE] Horizontal wheel zoom on snapshot charts anchors on the center of the current view. Vertical wheel zoom anchors on the pointer height.
reference lines
Right-click any chart to add a horizontal reference line at the cursor coordinate. Double right-click over the plot to open the horizontal line settings.
- Remove Line: Right-click near an existing line to remove it. The selection range is 2% of the visible vertical range.
- Scope: Reference lines are stored per ticker and per chart type.
- Persistence: Reference lines save to local browser storage when you click Save in the header.
Open the Colors panel to set the color, thickness, and style of horizontal marks. The Horizontal marks section has separate settings for these mark types:
- Reference line
- Term full line
- Term right ray
- Term left ray
expiry dropdown behavior
The DTE dropdown on Curve, Term, Tilt, Liquidity, and Fixed Delta Vols remains open while selecting multiple maturities.
- Close Dropdown: Press Escape or click anywhere outside the popup.
- Hidden Scrollbar: The list contains a hidden scrollbar. Use the mouse wheel over the open list to view additional expirations.
keyboard shortcuts
Keyboard input can navigate pane and header controls. Canvas navigation uses the mouse.
| Key | Action |
|---|---|
| Tab / Shift + Tab | Move focus across pane and header controls |
| Space / Enter | Activate the focused control |
| Escape | Close an open dropdown or cancel workspace renaming |
| Enter | Commit a workspace rename |
