Re: [tracecompass-dev] Customizing the tooltip in XY graph in theia trace viewer
Hi Alex,

Thanks for the interest in the theia trace viewer. 

The XY chart tooltip is currently solely generated in the front-end. The XY chart TSP API doesn't have an endpoint for querying tooltip information from the trace server back-end. Only the time graph data provider has such functionality. The plan has been to add that tooltip endpoint to the XY charts so that some domain specific information can be shown dynamically as part of the tooltip. The support of this feature would be a full-stack implementation. The interface ITmfXYDataProvider would be the starting point. Then the new interface would have to be called in the DataProviderService from a new xy tooltip endpoint. The typescript implementations will also need to be updated to support it in the front-end.

We don't have any estimate when we can prioritize this. However, we would gladly support and review any contributions for that.

> Also, I'm trying to prevent some quarks from showing up on the graph. I'm looking into it but would appreciate any help. Thank you!

The trace viewer front-end is quite lean and doesn't know about the domain and content that it displays. There is no filtering mechanism in front-end available to hide certain series. Filtering on the XY chart, would be interesting enhancement to the application. In general, the data to be shown is determined by the backend and the data provider implementation. So, if you have a custom data provider implementation, then you can remove certain series. If you don't have a custom data provider, then could extend the DataProviderService class, register the new DataProviderService class and in the extension you remove series that you don't want. If you do so, you would have to build your own trace server application based on the Trace Compass trace server.

I hope my answers help.

Subject: [tracecompass-dev] Customizing the tooltip in XY graph in theia trace viewer
 

Hi, I'm looking for a way to customize the tooltip in the theia trace viewer. Currently my plugin looks like this:

Graphical user interface Description automatically generated

 

I would like it to show the name of the quark instead of just the quark number, so the tooltip can act as a legend for viewer. Something like this:

Chart Description automatically generated

 

Any help is greatly appreciated. I have looked into the document but I couldn't find any convenient way to customize tooltip for XY graph like the fetchTooltip method in ITimeGraphDataProvider.

 

Also, I'm trying to prevent some quarks from showing up on the graph. I'm looking into it, but would appreciate any help. Thank you!

 

Regards,

 

Alex
