Custom templates do not work in Graph -> Matrics about druidplugin

Here is a quick hack to apply the template variable on groupBy field.

@knoguchi Thank you for your solution. I modified the code according to your way on dimension field, but it did not work. What should I do?

[knoguchi]

The code that I showed is for groupby query only. Please select groupBy and put the template variable name in the dimension field. If the template variable name is x, pls put $x in the dimension field.

@knoguchi I know that. It works for GroupBy.But it don't work in TopN.

[knoguchi]

You didn't even mention TopN besides the JSON. I hoped you'd get the idea as to how the template variables work in Grafana. It's easy to apply the same fix for other fields.

Created a PR #16.

hi @CarsonCao

I'm just starting using grafana and druid. How can you create template variable. I do not find any documentation for that.
Can you please send my a link or any exemple can help me to advance.

Thanks
