DevExtreme charts are not rendered inside an invisible container. You are required to render a chart when a bootstrap tabset tab become active using the render method.

An alternative to this solution is to use a scope variable in the tab's "active" option and then use an ng-if to only generate the chart when the tab is active.
e.g:
[HTML]<tabset><tabheading="One">One</tab><tabheading="Two"active="circleActive"><divng-if="circleActive"id="circularChartContainer"dx-circular-gauge="circularGaugeSettings"></div></tab><tabheading="Three"active="linearActive"><divng-if="linearActive"id="linearChartContainer"dx-linear-gauge="linearGaugeSettings"></tab></tabset>
