Following is a demo. When run it, it will display the sales bar chart for the period from January to December 2022. 

When the <- or -> button is clicked, it will zoom in to five bar charts and can be panned left/right. As written in the code, this translation operation is achieved through the Method 'setRange'. However, when the translation reaches a certain stage, there will be a situation where the bar chart does not match the data label. This Bug has been bothering me for some time. Is it related to the refresh mechanism of the qt bar chart?

To sum up, the data Label will encounter an error when setting the range. This is an issue of the underlying Qt library
