Hello All -
I am trying to plot Lat. and Long. of all airports globally on world map and it shows me all in one side of US map (screen attached for reference) but when use a country filter and filter it for a country, it works fine. Do we have any limit on number of data points allowed on world map?
Yes, you are hitting the limit. Since plotting all of these points on a world map would result in so many overlapping points anyway, you might consider switching to the Filled Map.
It is a known issue that there is a limitation about data points number in Map Visual, please vote this issue in this idea: https://ideas.powerbi.com/forums/265200-power-bi-ideas/suggestions/7394290-allow-more-data-points-to... .
And currently, the workaround is to add a calculated column to the location field which has Latitude and Longitude.
