Hi Eddy,
Thank you for contacting Syncfusion Support.
We have analyzed and created a sample using the provided image.
In the above sample link, we have achieved the timeline chart using the “pointers” and “labelRender” event. The pointers are used to render shapes or markers in the Linear Gauge. The labelRender event is used to customize the label text while rendering the labels.
We do not support the zooming feature and arrow in the Linear Gauge. When we analyzed for the feasibility for this requirement, we came to know that the zooming feature and arrow is not a valid feature for the Linear Gauge.
Please let us know if the above sample meets your requirements. If not, please let us know more details about your requirement. It will be helpful for us to analyze further and assist you better.
Regards,
Indumathi R
