Eraser

The eraser tool deletes chart drawings and annotations. Click an individual drawing to remove it, or use the panel controls to clear all drawings, indicators only, or annotations only. It is the most direct way to remove unwanted elements from your chart workspace.

With the eraser active, clicking any drawing object — lines, shapes, text labels, channels, or studies — immediately removes it. The eraser cursor shows a preview highlight on hover, making it clear which object will be deleted before you click. This preview uses a color-coded outline or highlight effect that intensifies as you hover closer to the drawing.

There is no confirmation dialog for individual deletions; they are immediate. However, every deletion is recorded in the undo history. Use Ctrl/Cmd + Z to undo a deletion if it was accidental. The undo stack supports multiple levels, so you can revert a series of deletions.

When the eraser cursor hovers over a deletable object, the object is highlighted with a subtle red or orange tint, and its anchor points may flash briefly. This visual feedback tells you exactly what will be deleted before you click. If multiple drawings overlap, the topmost drawing in the z-order is highlighted first. Scrolling the mouse wheel while hovering cycles through stacked drawings.

1. 1
   Activate eraser

   Select the eraser from the toolbar, or press Delete while a drawing is selected.
2. 2
   Delete a single drawing

   Hover over the drawing until it highlights, then click. The drawing disappears instantly.
3. 3
   Delete selected drawings

   With one or more drawings selected, press Delete or Backspace on the keyboard.
4. 4
   Clear all drawings

   Use the chart menu or right-click context menu to clear all drawings or all indicators.
5. 5
   Undo a deletion

   Press Ctrl/Cmd + Z immediately after deleting to restore the drawing.

The "Clear All Drawings" option in the chart menu provides a dialog that lets you choose what to delete: all drawings, all indicators, or both. It also lets you filter by drawing type — for example, delete all trendlines but keep horizontal lines and text labels. This gives you fine-grained control over bulk cleanup operations without affecting the entire chart.

Beyond the undo stack, deleted drawings can sometimes be recovered from the chart's version history if the layout supports auto-save and revision tracking. Check the layout revision history panel to restore a previous version of the chart if you need to recover drawings after a significant cleanup.

In shared chart layouts (multi-user environments), the eraser can delete drawings placed by any user. There is no per-user ownership of drawings by default. If you are working in a team, be mindful that your deletions affect all viewers. Some team setups support drawing locking, which prevents other users from deleting locked drawings without the lock holder's permission.

There are two deletion workflows with different strengths. The eraser tool is best for ad-hoc deletion of individual drawings — hover, confirm the highlight, click — especially when the drawing is not currently selected. The keyboard delete (Delete/Backspace) is faster when a drawing is already selected, as it requires no mouse targeting. The bulk clear via the chart menu is best for complete cleanup, with the optional confirmation dialog providing a safety net.

The bulk deletion dialog includes a filter panel that lets you select specific drawing types to delete while preserving others. For example, you can delete all trendlines and channels while keeping horizontal lines, Fib levels, and text labels intact. This filtered deletion is significantly more precise than clearing all drawings and re-adding the elements you want to keep.

On charts with hundreds or thousands of drawings, the eraser preview highlight system uses a spatial index to quickly determine which drawing is under the cursor. This ensures that the hover highlight responds instantly regardless of the total drawing count. When deleting large numbers of drawings via bulk operations, the deletion is batched for optimal performance rather than processed one at a time.
