How to make white space in Network Diagram viz unclickable ?

[rohit_d]

Hi, I have made Splunk Dashboard using Network Diagram viz (below snip). Requirement was to click on nodes so that it redirect to another URL or dashboard, which I have achieved using : Drilldown -> Link to Custom url -> https://xyz.splunkcloud.com/en-US/app/$row.value|n$

Issue is if i am clicking on white space in network diagram it is also taking me to another url which should not happen. I only need nodes in diagram to be clickable not white space. Any insight into this will be very helpful.
spl: 

| makeresults count=12
| streamstats count as id 
| eval from=case(id=1,"Machine1", id=2,"Machine2", id=3,"Load Balancer", id=4,"Machine3", id=5,"Machine4", id=6,"Web Server", id=7,"User", id=8,"Database")
| eval to=case(id=1,"Load Balancer",id=2,"Load Balancer",id=3,"Web Server",id=4,"Load Balancer",id=5,"Load Balancer",id=6,"Database",id=7,"Database") 
| eval value=case(id=1,"HEALTHY",id=2,"HEALTHY",id=3,"WARNING",id=4,"WARNING",id=5,"UNHEALTHY",id=6,"WARNING",id=7,"HEALTHY",1=1,"No Data")
| eval color=case(value=="HEALTHY","green",value=="WARNING","yellow",value=="HIGH","orange",value=="UNHEALTHY","red",value=="No Data","grey")
| eval value=case(id=1,"machine1_dashboard",id=2,"machine2_dashboard",id=3,"load_balancer_dashboard")
| fields from, to, value, color

Thanks.

Can you please try this?

<drilldown>
          <condition match="$row.value$!=&quot;&quot;">
            <!-- Provide custom link  !-->
          </condition>
          <condition>
            <!-- Put it blank !-->
          </condition>
        </drilldown>

Thanks for your reply. It partially resolved my issue.
If i refresh dashboard and click on white space, nothing is happening (which is good).
But when i click on any node to open another url/dashboard it opens fine and after that if i click on white space again it is taking me to same url which i clicked before.
It seems like when i click on node, url link is getting stored in $row.value$ and after that if i click anywhere in dashboard it is again taking me to same link.

It's look like is bug in Network Viz app. You can fix it by doing below change.

Open network-diagram-viz/appserver/static/visualizations/network-diagram-viz/visualization.js file.

Search for "_proto.handle_doubleclick_events"

Add below Patch code.

_proto.handle_doubleclick_events = function handle_doubleclick_events(obj) {
    if (this.parent_viz == null) {
        return;
    }
/* Patch Addded */
    if (obj.edges.length == 0) {
        return;
    }
/* Patch End */

.
.
.
.

Save it.

Bump the JS version.

Run the dashboard and check drilldown.

Enjoy
