Line charts Markers on click

Is there a way to make the markers on a line bigger as its really tricky to use the click function as the hit area is too small, it seems as if the border/stroke and the line itself is in front of the marker.

Or even better make the market appear in front of everything else so its all click able.

Im using latest wijmo 2, latest jQuery and developing on chrome

Anyone? I think this is quite a big issue not being able to cleanly and easily click on the markers…

Yeah, the documentation doesn’t cover a LOT of valid options. In this case, a series can have a markerStyle object, which accepts at least fill, stroke, opacity and width. You’re looking for ‘width’. Here’s a partial example of how to use it:

seriesList: [
  {
    label: "My sweet line",
    markers: {
      visible: true,
      type: 'circle'
    },
    markerStyle: {
      fill: '#d9007e',
      stroke: '#d9007e',
      opacity: 1,
      width: 3
    }
  },
  data: {},
  etc etc etc....
]

As far as I can tell, the only place this and many other useful options are documented is in the source code.

Still have issues with the markers not being clickable because of the lines…… This is causing issues with clients now….

Hello Ash,

Please refer to the following demo in which the markers and the line are clickable :

Could you please share your sample in which these markers are not clickable?

Thanks,
Richa

Hi, i posted to wijmo twitter account and its now sorted. There IS still an issue with wijmo where hit detection on markers isnt right and sometimes u click the line instead of the marker. The marker should always be in front of the line.

my sample is here: http://jsfiddle.net/WWbMj/7/
You can see an alert is fired everytime i click a marker but some time sit is unable to return the data attached to the marker because it clicking the line instead.

Chris Bannon edited my jsfiddle with a work around: http://jsfiddle.net/WWbMj/9/

UPDATE:

though tit was fixed….

Date return from click isnt correct:

http://jsfiddle.net/WWbMj/10/

Seems the line and the markers have different dates. I NEED the marker date.

Still dosnt work as u can see after the first red marker all the rest alert 23/3/2012 which isn’t the date that the marker is given.

As a paying customer i need this fixing. When i click on the marker i should be alerted the line value… the maker should ALWAYS be in front of the line… I believe this is a bug in the source code of wijmo charts.

Hello Ash,

Please refer to the modified jsFiddle :http://jsfiddle.net/WWbMj/18/

However, this approach does not work for datapoints on axis. I am escalating this as a bug to the development team.

Thanks,
Richa
