Simon, Regarding how you load the Google Charts library, you must not mix the old google.load and google.setOnLoadCallback methods with the new google.charts.load and google.charts.setOnLoadCallback methods. It is best to use only the new methods. So you will have to load https://www.gstatic.com/charts/loader.js.
But, since you are doing a Map chart, you need to do one more thing, until we fix this limitation. And that is, you ALSO need to load " https://www.google.com/jsapi";, but don't do any autoloading. This is because the Map chart still uses the old loader to load map data. So, like this... <script type="text/javascript" src="https://www.google.com/jsapi";></script> <script type="text/javascript" src="https://www.gstatic.com <https://www.google.com/jsapi>/charts/loader.js"></script> <script type="text/javascript"> *google.charts*.load("current", {packages:["map"]}); *google.charts*.setOnLoadCallback(drawVisualization); On Tue, Mar 15, 2016 at 7:12 PM, 'Simon Banton' via Google Visualization API <[email protected]> wrote: > Further to this, I have eliminated the "req id" error in Chrome by > replacing the jsapi autoload: > > <script type="text/javascript" src=' > https://www.google.com/jsapi?autoload={ > "modules":[{ > "name":"visualization", > "version":"1" > }] > }'></script> > > <script type="text/javascript"> > google.charts.load("current", {packages:["map"]}); > google.setOnLoadCallback(drawVisualization); > var wrap; > > with the following: > > <script type="text/javascript" src="https://www.google.com/jsapi"; > ></script> > > <script type="text/javascript"> > google.load("visualization", "1"); > google.charts.load("current", {packages:["map"]}); > google.setOnLoadCallback(drawVisualization); > var wrap; > > > > However, this now causes the intermittent occurrence of the error : "You > called the draw() method with the wrong type of data rather than a > DataTable or DataView". > > This seems to be entirely down to network response time - reloading (or > shift reloading) will result in the map appearing rather than the error. > This is completely reproducible. > > Here is a link to the page using the new code that doesn't trigger the > Chrome console warning about missing req id but instead has the > intermittent new error: > > http://web.org.uk/tmp/barrowmap/v13.html > > From this I surmise that the Chrome "req id" error is related to the > autoload mechanism for jsapi > > So I have swapped one error (req id) for a different, intermittent, one > (wrong type of data).
