Provide Clearer Design for Changing the Minimum Maximum Stretch

[AndyAnderson]

In version 2.9 of ArcGIS Pro, the way that one sets the minimum and maximum values when choosing that type of stretch are very unclear, as is the feedback that this has been accomplished. My idea is to restore the way it used to be in ArcMap!

1. There should be an edit button allowing direct editing of the minimum and maximum values in the initial display.
2. The design of the controls for the histogram range should make it clear that the values are editable, perhaps surrounded by dashed boxes that become solid as well as highlighted when one double-clicks on them.
3. Whether changing the range values as in #1 or as in #2, the resulting minimum and maximum values should be displayed in the main page of the symbology dialog, instead of always showing the full range, as happens now.
4. Update your documentation to describe these two possibilities!

Background:

In ArcMap, the actual values of the stretch are displayed, initially the full extent, and there is an edit button that clearly opens boxes around the minimum and maximum values whose values can be changed. As with other symbology, the labels that one uses change to match, but they are otherwise independent and can be adjusted, and don’t even have to be numeric. 

In ArcGIS Pro, there is no edit button for the minimum and maximum values, and they have no indication that they can be changed. Only due to years of experience with computers did it occur to me that maybe if I double-clicked on them I might be able to change them, but that doesn’t work. Changing the “Label” values, which have boxes suggesting they can be changed, doesn’t change them, either (nor should it, to be consistent). 

Custom Minimum-Maximum Stretch for Worldwide Elevation Dataset

Histogram Range with Editable LimitsOnly by poking around did I discover that if I clicked on the button Histogram, I could then drag the histogram range close to the values I wanted. Again guessing — because there was no visual indication — I double-clicked on one of the numeric values displayed below the range indicators, and it highlighted and allowed me to set a precise value.

Unfortunately, even as I changed the range values on the histogram, back on the main view the values did not change, and still showed the full range!

Thanks for fixing this.

Thank you for including images as it helps to see exactly what you're describing. For your Statistics section, you have that set to Dataset which uses the Min and Max from the dataset which is why you cannot change those. Did you try the Options button which allows you to change to Custom?

Choosing "Custom Uses user defined statistics" allows you to set the Min and Max values directly:

I hope this helps!

Thanks, that does work but it is not any clearer. I have no reason to expect that changing the range of the statistics one wants to calculate should also change the stretch range, and in fact I would not want it to do so!

Assuming this is the “correct” approach, the other issue is that the labels don’t update to show that that the stretch range has changed. And the histogram is also not updated.

So I don’t believe this is the correct solution.
