Choropleth map returns "No data" in some cases, but then displays contents after switching tabs
If you open a DF https://de-qa.siscc.org/vis?lc=en&df[ds]=qa%3Astable&df[id]=DF_GOV_CORE_RESULTS_TEST&df[ag]=OECD.GOV&df[vs]=2.0&av=true&pd=%2C&dq=A.......&ly[rw]=MEASURE%2CUNIT_MEASURE%2CAGE%2CEDUCATION_LEV&ly[cl]=TIME_PERIOD&to[TIME_PERIOD]=false&lo=2&lom=LASTNPERIODS&vw=tb and go to Chart -> "Color map world countries", it will display "No data". If you start adjusting some filters, it will still display "No data". But if at some point you go to the Table view and after to the Map view, without changing filters, the map will be displayed.
When opening choropleth math from a link (https://de-qa.siscc.org/vis?lc=en&df[ds]=qa%3Astable&df[id]=DF_GOV_CORE_RESULTS&df[ag]=OECD.GOV&df[vs]=2.0&av=true&pd=%2C&dq=A..CONFNG.PCT_POP._T._T._T.TG&ly[rw]=MEASURE&to[TIME_PERIOD]=false&lo=2&lom=LASTNPERIODS&vw=cp&mp[id]=world&mp[names][en]=world%20countries&mp[names][fr]=pays%20du%20monde&mp[lv]=countries&lb=bt), it displays "No data", but if you go to the "Table" tab and later to the "Chart" tab, then the data will be displayed.
