I am trying to create tree structure in Power BI uing d3@3.5.5. But I am having some issue with it. I have a simple update function as shown below.
public update(options: VisualUpdateOptions) { console.log("hello1"); var tree = d3.layout.tree() .size([400, 400]); console.log("hello2"); }
As you can see in above code, I am priting hello1 to console then creating tree object using d3 then printing hello2 to finish off. The problem is that I can see the hello1 on the console but I can not see hello2 no matter how many time I refresh the visual. See screenshot of console below.
Can someone please tell me why I can not see hello2 into the console?
Solved! Go to Solution.
There's a JavaScript exception. Our recommendation is to wrap update into try-catch to figure out a root of this issue.
public update(options: VisualUpdateOptions) { console.log("hello1"); try { var tree = d3.layout.tree() .size([400, 400]); } catch(e) { console.log(e); } console.log("hello2"); }
