Display progress of a computation together with estimated completion time

Contributed by: Jon McLoone


represents a progress indicator and remaining time estimator with the range xmin to xmax.

Details and Options

xmin and xmax should be chosen to indicate the expected range of values that x must take before a computation is complete.
All options for ProgressIndicator are supported.


Basic Examples

Display an estimate of completion time for a simple Do loop:

Monitor[Do[Pause[Random[]], {x, 0, 30}], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 30}]]

Display an estimate of completion time for a simple While loop:

x = 0; Monitor[While[x < 200, Pause[Random[]]; x += RandomReal[10]], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 200}]]


Control the refresh rate of the estimator. Note that a refresh rate shorter than the expected interval between changes to the tracked variable will result in an estimate that rises in a sawtooth, especially early in the process:

Monitor[Do[Pause[RandomReal[1]], {x, 0, 60}], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 60}, UpdateInterval -> 5]]

If the progress is expected to be nonlinear, then use “History” to consider only recent progress. This example resets the estimator each time 10% progress is made:

Monitor[Do[Pause[x/30], {x, 0, 60}], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 60}, "History" -> 0.1]]

Appearance  None will not display the ProgressIndicator:

Monitor[Do[Pause[Random[]], {x, 0, 30}], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 30}, Appearance -> None]]

Possible Issues

If the tracked symbol does not fall in the expected interval, then no estimate is returned:

If the tracked symbol does represent progress monotonically from the start value to end value, then the time estimates are meaningless:

Monitor[Do[Pause[RandomReal[1]]; x = RandomReal[{0, 60}], {60}], ResourceFunction["ProgressIndicatorEstimator"][Dynamic[x], {0, 60}]]
