Current behavior
Number Card chart in Internet Explorer only showing 'Name' label but NOT showing 'value' label after rendering and label alignment is also not proper. But same is working fine in Chrome browser.

Expected behavior
'Value' label also should be shown in I.E after rendering.

Reproduction of the problem

For below sample data Number Cards charts shows only 'Name' label in I.E but both 'Name' & 'Value' labels are properly shown in Chrome browser. Also label alignment is not proper in case of 'Name' label in Internet Explorer.

[ { "name": "Germany", "value": 40632 }, { "name": "United States", "value": 49737 }, { "name": "France", "value": 36745 }, { "name": "United Kingdom", "value": 36240 } ]

For above data Number Cards rendering screenshot in Chrome Browser

Hey guys,

just wanted to ask if anything happened.
It obviously still does not work in IE11 even for the demo.

Main issue seems to be the foreignObject which is not supported by IE 11

<foreignObject xmlns="http://www.w3.org/2000/svg" class="trimmed-label" alignment-baseline="hanging" x="20.25" y="97" width="122" height="82">
        <p style="color: rgb(211, 212, 215); line-height: 15px; font-size: 15px;">LabelText blabla</p>
      </foreignObject>

Did anyone find a short term fix using javascript or any polyfill that can be used ?

[Darshan-popin]

if (typeof SVGElement.prototype.contains === 'undefined') {
SVGElement.prototype.contains = HTMLDivElement.prototype.contains;
}

Add the Javascript code into the polyfill.ts that should work,.. I know it's a dirty fix but works for now

Hi,
thanks for your reply Darshan

I checked my polyfills.ts - I had already included this one but it didnt help. The numbercard itself is available - its just the label in the numbercard which does not appear.
Same as described above (see screenshots from rishi-ios)

polyfills.ts

Hey guys, I have the same issue, and none of the above solutions worked so far.
Could anyone please give a hint how to fix that?

[denssle]

Hey,
I would be also interested.

[Confusedfish]

I also had this problem of the values not lining up. I eventually tracked it down to IE & Edge not supporting the alignment-baseline="hanging" attribute on the SVG template. So when the template placed the value in Chrome it correctly set the position using the Y as the top of the text and then in IE / Edge the Y is the bottom of the text instead.

To get around the issue I modified the SVG template to use alignment-baseline="baseline" instead and then adjusted the Y value accordingly, i.e. [attr.y]="textPadding[0] + textFontSize" the + textFontSize being the important bit

[deepdev1]

@Confusedfish, may I know where exactly to apply those changes (where to find the SVG template). My html has only <ngx-charts-number-card> with property bindings?
