However, you have the same longitude and latitude for several locations that belong to different companies. Pune and Aliabad for example belong to A1 and A2 respectively and have the exact same location, meaning that only one colored point will be shown if you select both locations at the same time.
This is what I did using master dimension and assigning colors to A1, A2, A3, and A4. You can use any hex color you want. However, this functionality is not available in 3.2. I recommend that you upgrade your QS to the latest version.
