|Home ChartPack RChart Class TContourPlot Methods RectFrame|
The method RectFrame displays a framed rectangle. The lower left corner and the upper right corner are specified by the positions (x1, y1) and (x2, y2), respectively. The frame may assume one of four styles (parameter FrameStyle ): fsLowered, fsRaised, fsEmbossed, fsEngraved
The frame can be drawn in different coordinate system modes: version  uses the world coordinates (these are the coordinates shown at the axes of the chart), version  uses the screen coordinates (pixels), and versions  and  mix them. Using screen coordinates (which are declared as integer) has the effect that the frame remains at a fixed position even if the chart is panned or zoomed. Using mixed mode coordinates ( and ) allows to implement a "stretching" effect, with one corner of the rectangle staying in place and the other moving with the world coordinate system.
The colors of the boundary are determined by the parameters ShadowColor, and HiLightColor, the color of the inner area is determined by the property FillColor. The line width of the boundary is always 1 pixel.
