## Description

Scatterplot for eBay adds a price-history panel directly to eBay search pages, so you can see at a glance what items are actually worth before you buy or sell.

Pick the listings you care about and plot their prices on an interactive chart:
<ul><li><strong>Sold listings</strong> are charted by sale date, revealing real price history over time.</li><li><strong>Active listings</strong> appear in a separate price-distribution view, sorted by price so clusters and outliers stand out.</li></ul>
Because your selections are saved, you can page through the results and keep adding listings. The chart accumulates points from every page you visit.

<strong>Features</strong>
<ul><li>Interactive price chart docked to any edge of the screen (top, right, bottom, or left)</li><li>Per-listing checkboxes to choose exactly which items to include</li><li>"Plot all" to add or remove every listing on the page at once</li><li>Currency conversion: choose a display currency and all prices are converted from their original listing currencies using live exchange rates</li><li>Drag to redock: move the panel to any edge by dragging its header or tab</li><li>Resizable: drag the panel's edge to expand or contract it</li><li>Dark and light themes</li><li>Adjustable text size</li><li>Remembers everything between visits: selections, dock position, theme, font size, and open/closed state are all saved</li></ul>
