Rt-Tools2D is a selection of components to generate two dimensional Cartesian plots: *TRtCaptionEdit: This is a special edit control supporting enhanced styles as bold, italic, underline, strikeout, subscript, superscript and symbol font. This is especially interesting to alter TRtLabels which supports the same styles. *TRtLabel: Label supporting enhanced styles as bold, italic, underline, strikeout, subscript, superscript and symbol font. It can be drawn in any angle. *TRtGraph: The main component of a 2D-plot. Just place on a form and the plot will be drawn automatically. Supports unlimited number of line series, unlimited number of axis in any position, auto zooming, grids ... *TRtAxis: The axis of the 2D-Graph. You can add as many of them to the graph as you like to any position: top, bottom, left or right. You can alter fonts, scaling, tick marks ... *TRtRealVector, TRtLiveVector: The components to store the numerical data. The data added to the LiveVector will automatically update also the ranges of the connected Series, which will update the axis ranges. You can place as many Vector components as you like to a form and connect also to different series. You can add a unlimited amount of real data to each vector as to a dynamic array or a list which automatically adjusts its size. *TRtLineSeries, TRtDataSeries, TRtDataWithErrorSeries: These components represent the lines of the 2D-Graph. You can place a unlimited number of Series to the form and connect to the 2D-Graph. The X-and Y-data can connect to any data vector as described above. The data can also be assigned any Axis available with the graph. *TRtLinerRegressionLine, TRtPolynomLine, TRtFittedLine, TRtInterpolatedLine, TRtDifferential, TRtIntegral: Calculated Lines updating automatically. *TRtLegend: Place this component to a form or inside the 2D-Graph and connect to the graph. It will automatically display a legend including the settings of the Series and their captions.
