Set Histogram Number of Bins...

This is only available in the right-click menu of a histogram. When invoked, it pops up a non-modal slider dialog like the following:

Figure 13-12. A slider dialog to set number of bins in a histogram

---> images/number-of-bins-slider.png <---

This slider dialog is registered in the scenegraph under the histogram viewport where you invoke this menu entry.

A histogram can only have at most one slider dialog around to change its number of bins no matter how many times you invoke this function. If there is already a slider dialog around and you invoke this function again, the focus will be transferred to the slider dialog. Additionally, if this slider dialog is buried by other windows, invoking this function will also bring it up front.

If this function is invoked from a trellis display of histograms the number of bins in its panel plots, if any, will be changed, too. If this function is invoked from a panel plot of a trellis display of histograms, the end effect is equivalent to invoking it on the associated trellis display.
