Description

This PR addresses several inconsistencies within the current charting implementation to hopefully simply future development.

• Chart options were a bit messy, mixing ChartOptions, AxisChartOptions and base chart properties. Making customization inconsistent.
• Data input varied between chart types, some used raw double[], others had custom structs.
• The old base class hierarchy (MudCategoryChartBase, etc.) didn’t clearly separate radial vs. axis charts, making extension difficult.
• Label parameters like XAxisLabels and InputLabels were named differently across charts even though they served the same purpose.
• Series visibility toggling was technically configurable for all charts but wasn't functional on all.

Breaking Changes

Nodes no longer need to be explicitly defined. They are generated based on the edges provided.

BarChartOptions, LineChartOptions, HeatMapChartOptions, DonutChartOptions, PieChartOptions, StackedBarChartOptions RadarChartOptions, RoseChartOptions, TimeSeriesChartOptions, SankeyChartOptions

Data Model Migration

• Replace direct arrays (double[]) with ChartData
• Replace TimeSeriesChartSeries with ChartSeries

Example

// OLD 
<MudTimeSeriesChart 
          ChartSeries="@series" 
          AxisChartOptions="@axisChartOptions"/>

// NEW 
<MudChart ChartType="ChartType.Timeseries" 
          ChartSeries="@series" 
          ChartOptions="@timeSeriesOptions" />

New Features

✅ Show values within Pie Chart segments
✅ Bar and Stacked Bar Chart justification options
✅ Combination Charts (e.g. Bar + Line overlay) - applies to Axis charts ONLY
✅ Interchangeable Charts - all chart types can be converted to other chart types
✅ Tooltip customization (TooltipTemplate, TooltipPositionFunc)

📈 New Chart Types

✅ Radar Chart (ChartType.Radar)
✅ Rose Chart (ChartType.Rose)
✅ Mixed/Combination Charts

Enhancements

✨ White tooltip text with black stroke + drop shadow (better visibility)
✨ Series visibility toggling for all chart types
✨ Stacked Bar charts support negative values
✨ Dynamic chart scaling on visibility changes
✨ Dynamic font scaling for HeatMap cell values
✨ HeatMap tooltips match style of other chart tooltips
✨ INumber<T> support - no longer restricted to double values
