Looking for guidance/example on how to use an icon/image in place of the data point in a line chart? I’m using react-chartjs and importing Line wrapper component. Not entirely sure how to implement drawImage from Chartjs docs. I’m somewhat new to both so I may be overlooking something obvious. Your help is greatly appreciated.
Best example I can find for the effect.
This is the chart I have so far: react-chartjs line mood tracker

I am using renderHeader to build a custom header for my data-grid, and i would now like to place the sort-direction icon within this custom header.
I have been unable to figure out how to go about this. Any hints?
I suspect it might involve importing "GridColumnHeaderSortIcon" - i have not been able to get any results with this though.
Thanks in Advance

I am working with the ScalaJS library
https://github.com/fancellu/scalajs-leaflet and I am looking to incorporate some custom javascript from https://jackzoushao.github.io/leaflet-marker-direction
The key functionality is the ability to rotate the markers based on the direction of travel.
Any tips on how to achieve this will be greatly appreciated.
Look at
https://github.com/fancellu/scalajs-leaflet/blob/master/core/src/main/scala/com/felstar/scalajs/leaflet/Leaflet.scala
Note the Marker, they create an AngleMarker
Try creating appropriae AngleMarker scala code, and pull in the js
Also look at how I pulled in some GeoJSON.js object

I am new to SwiftCharts so I am still trying to understand how it works. I wanted to draw a cubic line chart, however, to no success.
As far as I understand from this example, the view that would contain the chart should be of class "Chart". However, as you can see from the screenshot, I cannot find such class in the drop-down list.
Could you please tell me how to proceed in order to draw cubic line chart using SwiftCharts?
Thank you very much!
A bit late, but will answer anyway: The view has to be of class ChartBaseView, not chart! Chart is just a wrapper (not a view). Here is a snippet for autolayout: https://gist.github.com/i-schuetz/f6e285eb0c86bb831510
I'm using Java and OpenXLS to write out an Excel spreadsheet. I want to set the font of a chart. I used the setFontChart() method but it does not work. Can anybody help me, please? :)
