I can successfully change the point symbol used in the measurement widget in 3.13. However, the point symbol in the results is too small to see. Is there a way to resize the symbol in the results? Please see the attached png.

thanks,

Janice.

  So I found a workaround for this issue. Here is a full sample:

Janice,

  There is not a great way to do this but this will work:

.esriMeasurement .esriMeasurementResultTable tr:nth-of-type(3) > td > img{
  height: 50px;
  width: 50px;
}

Hi Robert,

I did try this but it made no change for me. If I go into the development tools in ie I can change this manually and it helps a little but still it does not persist.

getting the unique selector from Firefox I get:

tr.esriMeasurementTableRow:nth-child(3) > td:nth-child(1) > div:nth-child(1) > svg:nth-child(1) > image:nth-child(2)

I have tried this in Firefox, Chrome, and IE11 with no luck.

Thanks,

Janice.

Hi,

I can confirm Robert's solution works for me. Just added his code to my css template and works without any problem.

Tested in Firefox 37.02.

Janice,

   The image in your attachment how are you specifying it? Is that the correct image? Like Radek confirms I had no problem changing the size of the image using the provided css.

Robert,

Your suggestion does work if I use the default marker symbol that the measurement widget uses. the issue I am having is trying to resize a custom marker symbol. I tried your code in the sandbox for the sample and it did not work there either. The sample is located at: ArcGIS API for JavaScript Sandbox

Let me know if I am way off on this.... it is entirely possible that I am doing something funky!

Sorry my original post did not really state that I was using a custom symbol.

Thanks,

Janice.

Janice,

   OK I see now that the dijit creates a SVG of the picture marker symbol and it is miniture!... Let me see what I can come up with.

Janice,

   I think that you need to call tech support and log this as a bug, referring them to your sandbox example. They seem to creating the SVG incorrectly.
