Large extents of data in a layer can reduce coordinate precision in the Vizex OpenGL renderer. When the "Zoom limit exceeded" warning appears in Vizex, it indicates that precision limits have been reached. Zooming past this point will likely result in rendering artifacts (data not drawing in the expected location, labels not loading, etc.) due to a lack of coordinate precision. The most common cause of this warning is spurious/errant data points in one of the files displayed. This article will outline the workflow to identify and rectify the issue in the offending file.
1) Systematically show/hide layers from the Vizex Layer Display until the warning goes away (you will need to use the zoom function to check). When the warning goes away, you know the problematic file is associated with that layer.
2) Open the data file associated with that layer and sort by one of the X, Y coordinate fields. In this example, sorting in descending order revealed a coordinate point that is much larger than the rest of the points. Keep in mind, this can also occur for data points much smaller than the rest of the points, so you may need to try sorting in ascending order. (Caution: do not save the file after sorting. It's best to keep the file in its original state - this is especially important for string files).
3) Delete/edit that record
4) Save the file
5) Refresh Vizex
