The ZoomStat command command zooms to a graphing window that accurately represents all the currently defined stat plots (see the PlotN( commands). You can think of it as ZoomFit, but for plots rather than equations.

The specific function of the command is as follows: first, the minimum and maximum X and Y coordinates that stat plots will be using are calculated. Xmin, Xmax, Ymin, and Ymax are calculated to fit all these coordinates plus a padding on either side. The padding is 10% of the unpadded range on the left and right (for Xmin and Xmax), and 17% of the unpadded range on the top and bottom (for Ymin and Ymax).

Of course, the exact function varies slightly with the type of plot defined. For example, Ymin and Ymax will not be affected by Boxplot and Modboxplot plots, since they ignore Y-coordinates when graphing. Also, Histogram fitting is a bit trickier than others. Xscl and Yscl also are changed for histograms, though not for the other plots.

For all plots except Histogram, ZoomStat will create a window with Xmin=Xmax (or Ymin=Ymax) if the X range (or Y range) of the data is 0. This will throw an ERR:WINDOW RANGE. If a Histogram causes this error, though, ERR:STAT is thrown, and then when you access the graphscreen ERR:WINDOW RANGE will occur.

Error Conditions

  • ERR:INVALID is thrown if this command is using outside a program (although the menu option, of course, is fine).
  • ERR:STAT is thrown when trying to ZoomFit to a Histogram with only one distinct number in the data list.
  • ERR:WINDOW RANGE is thrown when the window ends up being empty.
