I'm trying devise a simple way of displaying GPX tracks on a Google map, partly as an exercise to get to know Google Charts, since I'm sure there are already tools that do it.
I notice that https://developers.google.com/chart/interactive/docs/gallery/map#data-format says that you can display a maximum of 400 points on a map. Has anyone found a way of exceeding this limit to cope with tracks that have more than 400 points? In my very simple hard-coded example, I simply edited the GPX file so as to include only those points with timestamps of hh:mm:00, hh:mm:15, hh:mm:30 and hh:mm:45 as a crude means of data-reduction :-) I wonder how I tell Google Maps not to display a marker at each point and only to display the lines between the points. Maybe by setting null markers (ie non-existent path) in var options = { icons: { default: { normal: '/path/to/marker/image', selected: '/path/to/marker/image' }, customMarker: { normal: '/path/to/other/marker/image', selected: '/path/to/other/marker/image' } } }; -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
