A feature is urgently needed to allow customization of color and font size on the Account Summary Graph. When switching from light to dark mode, visibility becomes a serious issue. The current color scheme lacks sufficient contrast, making key data especially the NLV (Net Liquidating Value) difficult to read.

For example, the NLV text appears in a dark blue shade that blends into the black background, making it nearly impossible to interpret the data without significantly increasing screen brightness, which is inconvenient and not ideal for prolonged use.

It is recommended that users be given the ability to customize the graph's colors and font sizes. Adding multiple color options for better visibility in different themes (especially dark mode) would greatly improve user experience. This issue requires urgent attention as it significantly hinders usability.
