Solving Problems with D3.js Mouseover and Focus + Context

I am just starting to explore the world of D3.js, I've completed a few tutorials and dived straight into my initial project. My intention was to combine the concepts from the following examples with some modifications to suit my specific requirements. However, I have encountered two main issues that I could use some help with:

Focus+Context via Brushing

and

X-Value Mouseover

  1. The mouseover feature is not displaying correctly; it appears to the left of the chart instead of where expected. It seems like a minor issue but I haven't been able to identify the cause.
  2. I'm struggling to find a way to show the "Safe Value" text outside the chart next to the line. EDIT 2 - I have managed to resolve this issue.

Any assistance or guidance on resolving these problems would be highly appreciated.

Here is the CSS code snippet:

body {
    font: 10px sans-serif;
}

svg {
    font: 10px sans-serif;
}

.line {
    fill: none;
    stroke: steelBlue;
    stroke-width: 1.5px;
    /*clip-path: url(#clip);*/
}

.axis path,
.axis line {
    fill: none;
    stroke: #000;
    shape-rendering: crispEdges;
}                               ... (trimmed for brevity)

Javascript Code:

var margin = {top: 10, right: 15, bottom: 100, left: 60},
   ... (trimmed for brevity)

// The rest of the Javascript code can be found in the original post

Answer №1

In addressing your second issue, the current code is causing the text to be positioned outside of the visible area. To correct this, you can adjust the arguments within the translate function as shown below:

.attr("transform", "translate(" + (width - 35) + ",30" + ")")

Feel free to customize these values to your liking - just remember to include a minus sign before the x-coordinate.
