name: add-chart description: Add a new Recharts visualization with theme-aware styling to the dashboard

When adding a new chart to this dashboard application using Recharts:

1. Use the useChartColors hook for theme-aware colors:

   const colors = useChartColors();
   

   This hook automatically updates chart colors when theme changes between light/dark modes.

2. Choose the appropriate chart type:

   • LineChart: For trends over time (sales, growth, etc.)
   • BarChart: For comparisons across categories
   • PieChart: For proportions and distributions
   • Mini charts: Use MiniLineChart or MiniBarChart from @/lib/charts for compact displays

3. Apply consistent theming to all chart elements:

   • Grid: stroke="hsl(var(--border))" opacity={0.5}
   • Axes: fill="hsl(var(--muted-foreground))" for tick labels
   • Tooltips: Use the standard tooltip style object:

     contentStyle={{
       backgroundColor: "hsl(var(--popover))",
       border: "1px solid hsl(var(--border))",
       borderRadius: "8px",
       fontSize: "12px",
       color: "hsl(var(--popover-foreground))",
     }}
     

   • Chart colors: Use colors.chart1, colors.chart2, etc.

4. Make charts responsive:

   • Wrap in <ResponsiveContainer width="100%" height={250} className="sm:h-[300px]">
   • Use small font sizes: fontSize: 10 for axis labels
   • Adjust chart sizes for mobile: use Tailwind responsive classes

5. Component structure for full-size charts:

   function ChartComponent() {
     const colors = useChartColors();
     return (
       <ResponsiveContainer width="100%" height={250}>
         {/* Chart implementation */}
       </ResponsiveContainer>
     );
   }
   

6. Add to the charts array in DashboardCharts.tsx:

   {
     title: "Chart Title",
     description: "Chart description",
     component: YourChartComponent,
   }
   

7. Mark component as client-side if it's in its own file:

   "use client";
   

Examples

Add a line chart for sales data

function SalesLineChart() {
  const colors = useChartColors();
  
  return (
    <ResponsiveContainer width="100%" height={250}>
      <LineChart data={salesData}>
        <CartesianGrid 
          strokeDasharray="3 3" 
          stroke="hsl(var(--border))"
          opacity={0.5}
        />
        <XAxis 
          dataKey="month" 
          tick={{ fontSize: 10, fill: "hsl(var(--muted-foreground))" }}
        />
        <YAxis 
          tick={{ fontSize: 10, fill: "hsl(var(--muted-foreground))" }}
        />
        <Tooltip contentStyle={{
          backgroundColor: "hsl(var(--popover))",
          border: "1px solid hsl(var(--border))",
          borderRadius: "8px",
        }} />
        <Line 
          type="monotone" 
          dataKey="value" 
          stroke={colors.chart1}
          strokeWidth={3}
        />
      </LineChart>
    </ResponsiveContainer>
  );
}

Add a mini chart to a card

import { MiniLineChart } from "@/lib/charts";

const trendData = [
  { x: "Mon", y: 10 },
  { x: "Tue", y: 15 },
  { x: "Wed", y: 12 },
];

<DashboardCard title="Trend" value="142">
  <MiniLineChart data={trendData} />
</DashboardCard>

Tips

• Charts automatically adapt to theme changes using CSS custom properties
• Always test charts in both light and dark modes
• Use the five predefined chart colors (chart1-chart5) for consistency
• Keep data visualization simple and readable on mobile devices
