 Wijmo Team Member | xanadu posted on October 29, 2012 at 1:12 pm  Hi guys, I’ve noticed that wijmo tooltips are sometimes slow (especially in Firefox for example). Would it be possible to set static position for tooltip (without following cursor)? Or any ideas for different optimization? Or maybe general ideas how to optimize wijmo widgets? | |

 Wijmo Team Member | Richa posted on October 30, 2012 at 12:31 pm Hello Xanadu, I am unable to reproduce the performance issue in Firefox 16 and WijCompositeChart. You can set the position of hint field using the offsetY and offsetX options as : hint: {
content: function () {
return this.data.lineSeries.label + ‘\n’ +
this.x + ‘\n’ + this.y + ”;
},
contentStyle: {
“font-size”: 10
},
offsetY: -10, offsetX: -10
}Thanks, | Answer |
| Wijmo Team Member | xanadu posted on October 30, 2012 at 12:35 pm Richa, offsetX and offsetY sets only offset from bar. I would like tooltip that doesn’t follow cursor. | Answer |
| Wijmo Team Member | Richa posted on November 1, 2012 at 11:54 am Hello Xanadu, The tooltip is shown on hovering over the datapoints. SInce a compositechart has multiple points, then it seems that the tooltip is following cursor as there are multiple series. As a workaround, you may set the visibility of the default tooltip and show the tooltip on any other event, say button click. Please refer to the attached sample wherein the tooltip is shown for linechart’s first data point on button click. You can modify this as per your requirement. Thanks, | Answer |
| Wijmo Team Member | xanadu posted on November 2, 2012 at 7:05 am Richa, I noticed that problem doesn’t exists in line chart, because there tooltip is static (only animating when cursor is near previous/next data point). It’s ok. But on bar chart (attached image), one datapoint can be rectangle and inside this rectangle tooltip is following a cursor – could it be possible to set fixed position like in tooltip in linechart?

| Wijmo Team Member | xanadu posted on November 2, 2012 at 10:46 am Richa this is great, but: 1. This is fixed to first data point (bar) | Answer |
 Wijmo Team Member | dail posted on November 6, 2012 at 3:59 am Hi Xanadu,
$("#wijcompositechart").wijcompositechart({
......
hint: {
content:function(){
.....
},
relativeTo: "element"
}
})
Now it’s hard to give you a workaround for the feture. Please wait for the wijmo 2.3.0 | Answer |
