Integrating d3.js Trend Chart (Area + Line) as data studio community visualisation

I am a data scientist. Mostly use python and SQL for code. I am using data studio for visualizations.So I am unfamiliar to JS. I know-how data studio community visualizations works. I want to make this chart(without markers). I follow this. I tried but didn't get success. Can anybody with me on this? or refer me d3.js data studio integration resources.

Solution

  • I really not sure what you want but for the chart without markers here what I think you want:

    function addAxesAndLegend(svg, xAxis, yAxis, margin, chartWidth, chartHeight) {
      var legendWidth = 200,
        legendHeight = 100;

      // clipping to make sure nothing appears behind legend
      svg
        .append("clipPath")
        .attr("id", "axes-clip")
        .append("polygon")
        .attr(
          "points",
          -margin.left +
            "," +
            -margin.top +
            " " +
            (chartWidth - legendWidth - 1) +
            "," +
            -margin.top +
            " " +
            (chartWidth - legendWidth - 1) +
            "," +
            legendHeight +
            " " +
            (chartWidth + margin.right) +
            "," +
            legendHeight +
            " " +
            (chartWidth + margin.right) +
            "," +
            (chartHeight + margin.bottom) +
            " " +
            -margin.left +
            "," +
            (chartHeight + margin.bottom)
        );

      var axes = svg.append("g").attr("clip-path", "url(#axes-clip)");

      axes
        .append("g")
        .attr("class", "x axis")
        .attr("transform", "translate(0," + chartHeight + ")")
        .call(xAxis);

      axes
        .append("g")
        .attr("class", "y axis")
        .call(yAxis)
        .append("text")
        .attr("transform", "rotate(-90)")
        .attr("y", 6)
        .attr("dy", ".71em")
        .style("text-anchor", "end")
        .text("Time (s)");

      var legend = svg
        .append("g")
        .attr("class", "legend")
        .attr("transform", "translate(" + (chartWidth - legendWidth) + ", 0)");

      legend
        .append("rect")
        .attr("class", "legend-bg")
        .attr("width", legendWidth)
        .attr("height", legendHeight);

      legend
        .append("rect")

      legend
        .append("text")
        .attr("x", 115)
        .attr("y", 25)
        .text("5% - 95%");

      legend
        .append("rect")
        .attr("class", "inner")
        .attr("width", 75)
        .attr("height", 20)
        .attr("x", 10)
        .attr("y", 40);

      legend
        .append("text")
        .attr("x", 115)
        .attr("y", 55)
        .text("25% - 75%");

      legend
        .append("path")
        .attr("class", "median-line")
        .attr("d", "M10,80L85,80");

      legend
        .append("text")
        .attr("x", 115)
