Creates chart configuration for different chart types.

This helper can be used to generate chart.js configuration objects with sensible defaults for different chart types.

Creates a chart component with real Ash data.

This is an example of how to use the chart library with actual data instead of static demo data.

Example

# In your LiveView
def mount(_params, _session, socket) do
  chart_data = AshCharts.Helpers.fetch_chart_data(MyApp.User, %{
    x_field: :role,
    y_field: :count,
    aggregate_function: :count
  })
  socket = assign(socket, :user_chart_data, chart_data)
  {:ok, socket}
end

# In your template
<.chart_with_data 
  data={@user_chart_data}
  chart_type={:bar}
  title="User Statistics"
/>

Generates a color palette for charts.

Examples

iex> AshCharts.Helpers.generate_colors(3, 0.2)
["rgba(255, 99, 132, 0.2)", "rgba(54, 162, 235, 0.2)", "rgba(255, 205, 86, 0.2)"]

Returns empty chart data structure for error states.

Converts a field name to a human-readable label.

Examples

iex> AshCharts.Helpers.humanize_field(:total_amount)
"Total Amount"

iex> AshCharts.Helpers.humanize_field("user_count")
"User Count"
