Answer : Just set the label and tooltip options like so ... options: { legend: { display: false }, tooltips: { callbacks: { label: function(tooltipItem) { return tooltipItem.yLabel; } } } } Fiddle - http://jsfiddle.net/g19220r6/ add: Chart.defaults.global.legend.display = false; in the starting of your script code; It's just as simple as adding this: legend: { display: false, } // Or if you want you could use this other option which should also work: Chart.defaults.global.legend.display = false;

Answer : There is no need to take such drastic steps as completely rebuilding Ruby, reinstalling Rubygems from scratch or installing a version manager to solve this problem. There is simply a dependency cycle introduced by the release of hoe 2.3.0: rubygems-update 1.3.5 requires (among other things) hoe-seattlerb hoe-seattlerb requires hoe >= 2.3.0 hoe >= 2.3.0 requires rubygems >= 1.3.1 I wrote the blog post linked to by zipizap. To recap: If you've already tried to update, uninstall the latest rubygems-update first: sudo gem uninstall rubygems-update -v 1.3.5 Update to 1.3.0: sudo gem install rubygems-update -v 1.3.0 sudo update_rubygems Then update to latest: sudo gem update --system With the release of Rubygems 1.3.6, it looks like this problem may be gone. From the release notes: Development deps are no longer added to rubygems-update gem so older versions can update sucessfully. Oi - I feel your pain. I'll first ask the obvious;

Answer : You can use the exists filter combined with a bool/must filter like this: { "query": { "filtered": { "filter": { "bool": { "must": [ { "exists": { "field": "price" } }, ... <-- your other constraints, if any ] } } } } } DEPRECATED (since ES5) You can also use the missing filter combined with a bool/must_not filter: { "query": { "filtered": { "filter": { "bool": { "must_not": [ { "missing": { "field": "price" } } ] } } } } } The exists filter has been replaced by exists query from ES 2.1, though the working of it is the same. Also, t
