You are welcome! We just published a new video called Business Charts, which explains all the latest features of this plugin which we renamed recently.
Thank you! we have a lots of charts written using echarts and we are using Grafana more and more. this allows us to reuse what we have. the video is simple and easy to follow. Very helpful!
Appreciate the feedback. We love to hear what community is doing with ECharts in Grafana! Let us know if you interested to share your use case, tips&tricks on our blog. -- Mikhail
@volkovlabs I have some troubleshooting erros ECharts Execution Error data is not defined I am following exactly this video. Don't know whats going wrong
If you are using Grafana 10, `values.buffer` needs to be updated to `values`. Everything else should work as expected. Check our documentation for the latest examples: volkovlabs.io/plugins/volkovlabs-echarts-panel/
@volkovlabs This is awesome stuff. I have use echarts for multiple panels now. Is there a way we can show "No Data" when the result of the query is NULL with this plugin?
Thank you, I am Using Grafana9.0, And the databse is influxdb, I can't able to differentiate the Data for for each refId( Queries A,B,C) , as my requirment is to compare the Value of each refId and then Need to chnage the Colour automaticaly. const series = data.series.map((s) => { const sData = s.fields.find((f) => f.type === 'number').values.buffer; const sTime = s.fields.find((f) => f.type === 'time').values.buffer;

Дарья, здравствуйте! Использую apache echarts в работе для построения дашбордов. Столкнулся с проблемой, что если я разрабатываю дашборды на большом мониторе, то человек с маленьким монитором видит другую картинку... Не происходит пропорционального уменьшения размеров дашбордов, вместо этого легенда может наехать на график. Т.е. я не могу быть уверен, что пользователь будет видеть мои дашборды такими же красивыми, какими их вижу я на своём мониторе. Хотелось бы, чтобы графики и текст на графиках и легенде уменьшались(или увеличивались) пропорционально размеру экрана. Возможно ли это как сделать?
We are using grid in percentage to positioning and avoid collisions. ``` grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, ``` You can check various ECharts examples on echarts.volkovlabs.io
@@volkovlabs возможно ли как-то сделать пропорциональное уменьшение графиков? Например, на маленьком экране 14 шрифт уже не нужен, пусть там будет 10. А сейчас сохраняется размер шрифта и получает пересечение и обрезка слов на маленьком экране.
In the Apache ECharts code (function) I want to use ${__to} and ${__from} of grafana Variable, but it doesn't seem to work. Is there a way to use them?
Hi. I have been using your Echart Panel for almost a year for my Grafana Cloud, thank you very much. However, Grafana has upgraded my version to the latest stable version last week, and since then the Echart Panel is no longer working, giving this error message "ECharts Execution Error Cannot read properties of undefined (reading '0')". Appreciate it if you could share some input on the error.
Grafana updated the structure of the data frames in Grafana 10. If you use `values.buffer` just update to `values`: github.com/VolkovLabs/volkovlabs-echarts-panel/issues/174 Let me know if it helps. -- Mikhail.

Our plugins are signed for the default Root URL localhost:3000. If you are using a different URL: 1) You can allow unsigned plugins and delete MANIFEST.txt file. Take a look at github.com/grafana/grafana/issues/31125. Unfortunately, official Grafana documentation is broken at the moment. 2) Another option is to use NGINX reverse proxy and keep the default root URL for which the plugin was signed. 3) We can sign the plugin for your domain and help you install and configure it by sponsoring our open-source plugins: github.com/sponsors/VolkovLabs.

This is awesome stuff. I have use echarts for multiple panels now. Is there a way we can show "No Data" when the result of the query is NULL with this plugin?
You can return this graphic if results are empty:
```
option = {
graphic: {
elements: [
{
type: 'text',
left: 'center',
top: 'center',
style: {
text: 'No Data',
fontSize: 80,
fontWeight: 'bold',
lineDash: [0, 200],
lineDashOffset: 0,
stroke: '#000',
lineWidth: 1
},
}
]
}
};
```

omg, grafana is fucking impossible
We make a lot of things possible with our plugins. Apache ECharts, Dynamic Text and others are good examples what is possible with Grafana.
Table output is possible in echarts ?
What do you mean table output? Legend or Table view of data? There is a table view in the toolbar.
@@volkovlabs I want to display my output in table format which is row and column format. Reason is I want to download that as png format
