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!
- There should be an edit button allowing direct editing of the minimum and maximum values in the initial display.
- 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.
- 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.
- 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.
