If users can only switch between charts using small dots, it causes problems:
1. Hard to Notice and Use
Dots are often small and not clearly interactive.
Many users may not realize they can click them to change charts.
2. No Labels
Dots give no hint about what each chart shows.
Users must click blindly to find the chart they need.
Suggestion:
Option 1: Use Tabs
Each chart has a name.
Users can click a tab to see the chart they want.
Option 2: Arrows
Use arrows to go to the next or previous chart.
