We are happy to announce the release of the Business Charts Panel 4.3.0/4.3.1. This release include the following updates:
- Added an alert state and annotations.
-
Added the
getDataSourceSrvparameter to retrieve the entry point to data sources. - Updated U.S. and world maps in the GeoJSON module.
- Updated the plugin to the latest Grafana 9.4.7 toolkit and the Apache ECharts 5.4.2 library.
After the plugin review by the Grafana team, the getDataSourceSrv parameter was removed due to security reasons in v4.3.1.
The plugin was updated in the Grafana Plugins catalog on April 24, 2023.
100k downloads
We are pleased to announce that Business Charts Panel has been downloaded over 100,000 times. This extension is not a plug-and-play product and requires some learning. Our YouTube tutorials and documentation will undoubtedly assist you in mastering the plugin and revealing its unrivaled customization potential.
Alert State and Annotations
We added support for Annotations in Apache ECharts using mark lines. Data for mark lines is retrieved from the data.annotations object as explained in the product documentation.
const annotations = [];
data.annotations.map((a) => {
a.source.forEach((source) =>
annotations.push({
xAxis: source.time,
label: source.text,
lineStyle: {
color: source.color,
width: 2,
},
})
);
});
/**
* Data Sources
*/
const series = data.series.map((s) => {
const sData =
s.fields.find((f) => f.type === "number").values.buffer ||
s.fields.find((f) => f.type === "number").values;
const sTime =
s.fields.find((f) => f.type === "time").values.buffer ||
s.fields.find((f) => f.type === "time").values;
return {
name: s.refId,
type: "line",
showSymbol: false,
areaStyle: {
opacity: 0.1,
},
lineStyle: {
width: 1,
},
data: sData.map((d, i) => [sTime[i], d.toFixed(2)]),
markLine: {
data: annotations,
label: {
show: false,
},
symbol: ["none", "none"],
},
};
});
Entry point to data sources
After the plugin review by the Grafana team, this functionality was removed due to security reasons in v4.3.1.
We are testing a security-safe technique in the Data Manipulation plugin and plan to include it into Business Charts Panel.
Business Charts Panel allows you to retrieve an entry point of a data source. You can use the data source instance to perform any methods supplied by the data source.
async () => {
const targets = data.request?.targets;
if (targets.length && targets[0].datasource) {
const datasource = await getDataSourceSrv().get(targets[0].datasource);
notifySuccess(["PostgreSQL Version", await datasource.getVersion()]);
}
};
GeoJSON updates
GeoJSON files (U.S. and world maps) were synchronized with native maps provided within Grafana GeoMap. You may now quickly transition from GeoMap to Business Charts Panel to display visual maps, like we already did for the Website Analytics blog.
Panel Variables
We continue to explore with integrating DOM components straight into the Apache ECharts container to add more interactivity. This time, we introduced a dropdown box that lets you update Apache ECharts or establish a direct interaction with the data source through an entry point.
