Each slider has its own inspector. Access it by double-clicking anywhere in the slider, or with the slider selected, choose Object | Inspect Slider.
The slider's Properties panel makes it possible to do some really interesting and useful things with sliders. Each property is explained below or see Work with Dynamic Parameters (Sliders).
Slider name and value |
The first row in the panel contains the name and value of the slider. Both of these are editable. Of course, if you just want to change the slider's name or type a new value, you don't need the inspector for that; just do it directly in the slider. |
Formula |
Like an attribute or a measure, a slider can have its value determined from a formula. Double-click the Formula cell to edit the formula. There is quite a range of uses for sliders with formulas. See Define a Slider by Formula and Make a Slider Do a Random Walk for details. |
Max_updates_per_second |
When this property has no value, the slider will animate at full speed if there is no formula and recompute the formula value once if there is a formula. When the property has a positive value and the slider is animated, Fathom will move the slider or recompute the formula up to a maximum of this many times per second. Clear the cell's contents by deleting the value to remove the speed restriction. Note: Putting in a high value for this property will not make the slider go faster than it would with no value. |
Lower and Upper |
The bounds of the slider scale. You can also change them by dragging. |
Restrict_to_multiples_of |
Restricts the values the slider can have. For example, a value of 1 restricts the slider value to integers, and a value of 0.1 restricts the slider value to a precision of one-tenth. To return the value to blank, clear the cell by deleting its contents. Note: This restriction takes precedence over the formula, so although the formula value might be 1.23, if the property is 0.1, the slider will have a value of 1.2. |
Reverse_scale |
Normally, the axis of a slider has a scale that increases to the right. You can reverse its scale by changing the value of the property from "false" to "true". |
