Design-time
TChart4D is on the component palette, from the design-only packages Chart4D_VCL_D and Chart4D_FMX_D. The Object Inspector reaches the plot settings that hold a single value: Kind, Title, Subtitle, Source, Orientation, StackMode, LegendPosition, LegendReversed, ValueLabels, HighlightedSeriesIndex, DonutCenterText and ShowTooltips, each mirroring the property of the same name on Plot. Series, categories and annotations stay in code, because they do not stream to a DFM.
A chart with an empty plot draws a sample at design time instead of nothing: your own title, kind and legend with placeholder data that fits the chart kind.
Under RAD Studio 13.0 every package also targets Win64x, so a 64-bit IDE can load them.
Demos
Both demo forms moved into the designer, the VCL one into a DFM and the FMX one into an FMX file, each with the chart on it.
