Ghostfolio Chart Improvements Demo

+ +
+

Visual Improvements for Portfolio Analysis Charts

+

+ This demo shows the improvements made to chart visual comparability in + the Portfolio Analysis section. The key enhancements include: +

+
    +
  • + Date Range Filtering: Charts now properly scale to + show only data within the selected time period +
    • +
  • + Enhanced Visual Design: Improved color schemes, + better spacing, and clearer data representation +
    • +
  • + Better Readability: Cleaner axes, grid lines, and + tooltips for easier analysis +
    • +
+
+ +

Portfolio Performance Comparison

+ +
+
+

Before: Truncated/Unscaled Charts

+

+ Charts were not properly scaled when applying time period filters, + making data difficult to read. +

+
+ +
+
+ +
+

After: Properly Scaled Charts

+

+ Charts now automatically adjust to show only the data within the + selected time period with proper scaling. +

+
+ +
+
+
+ +

Investment Timeline Comparison

+ +
+

Enhanced Investment Timeline Chart

+

+ Improved visualization with better color coding and clearer data + representation. +

+
+ +
+
+ +

Dividend Timeline Comparison

+ +
+

Enhanced Dividend Timeline Chart

+

+ Better visual distinction for dividend data with improved readability. +
