Graph Point Format¶
The Data Points dialog for a TableCurve 2D Graph itself incorporates a copy of the current graph. All changes made in any of the point format options are immediately reflected in the graph. The entry fields serve either the Y or Y2 axis, depending on whether Y Axis or Y2 Axis is selected. The Y2 options will not be available if the graph contains a single plot. This option sets only the principal data points of each Y axis. Reference data sets, if present, use a preset format.
Size¶
A graph's data point size may be set from zero to ten. Size 0 points are always pixels (non-bar shapes) or lines (bar shapes), regardless of the device. If the graph specifies a bar shape, this option affects the width of the bar.
Shape¶
A graph's points may be set as square, circle, diamond, triangle down, triangle up, or plus symbols. You may also choose a bar graph where the bar's base is zero, or the Ymin or Ymax of the plot.
Fill¶
You may choose to leave the points unfilled or fill them with one of the four point colors within TableCurve 2D.
For Review Graphs, you may also choose Color by Residuals. Here the points are colored based upon the absolute value of the number of standard errors from the Y-predicted value. The default color schemes employ a coloring based upon ascending wavelength. Points less than 1 standard error are shown in blue, those between 1 and 2 standard errors are green, those between 2 and 3 standard errors are yellow, and those beyond three standard errors are red. Points that are beyond 2 standard errors may represent outliers which adversely impact the overall fit.
Options¶
- ·You may elect to have inactive points filled or unfilled. To differentiate inactive points on black and white printers, you will need to use unfilled inactive points.
- ·Points may be hidden entirely.
- ·A graph's points can be connected using lines.
- A graph's points can be connected using a cubic spline
- A graph's points can be connected using a cubic NURBS (non-uniform rational B-spline)
