Charts

TX Text Control for Windows Forms supports the insertion of chart controls of the type System.Windows.Forms.DataVisualization.Charting.Chart. This control is part of the .net framework since version 4, but can be added to prior versions. A chart can be positioned like an image or textframe, either geometrically or as a single character. Geometrically its position can either be relative to a paragraph to which it is anchored or relative to the complete document. The ChartFrame class handles the positioning of the chart in the document. A chart frame is always associated with a chart control which handles the appearance and the data of the chart. All charts in a document are contained in a ChartCollection. The collection can also be used to add charts to or to remove charts from the document. The chart collection can be obtained from a TextControl or ServerTextControl through the Charts property. The TextControl.ChartLayoutDialog method opens a dialog box which offers layout settings like positioning, size and text distances. A chart can be saved with the TX Text Control and the RTF format and is reconstructed during a loading process. With other formats the chart image is saved. If a document with charts is loaded on a system where no chart controls are installed, the chart's image is inserted.
