Menyesuaikan Garis

Ringkasan

Beberapa Google Chart, seperti Diagram Area, Garis, dan Kombo, memiliki garis yang menghubungkan titik data. Anda dapat menyesuaikan warna, ketebalan, dan garis putus-putus menggunakan teknik di halaman ini.

Mengubah Warna

Anda dapat mengubah warna garis yang menghubungkan titik data di Google Chart dengan dua cara yang sedikit berbeda: dengan opsi colors untuk mengubah palet diagram, atau dengan opsi series untuk menentukan warna rangkaian tertentu.

Dalam diagram berikut, kami menetapkan warna setiap deret secara eksplisit.

Opsi
        var options = {
          legend: 'none',
          series: {
            0: { color: '#e2431e' },
            1: { color: '#e7711b' },
            2: { color: '#f1ca3a' },
            3: { color: '#6f9654' },
            4: { color: '#1c91c0' },
            5: { color: '#43459d' },
          }
        };

Di atas, warna ditentukan oleh nilai heksadesimal (misalnya, '#e2431e', atau '#f00' untuk warna merah tersaturasi), tetapi juga dapat ditentukan dengan nama dalam bahasa Inggris. Contoh berikut mengilustrasikan hal ini dan juga menunjukkan cara mengontrol warna dengan memperbaiki palet diagram menggunakan opsi colors, bukan menetapkan warna untuk masing-masing deret. Satu perbedaan adalah jika Anda memperbaiki palet dan jumlah rangkaian lebih banyak daripada warna di palet, warna tersebut akan digunakan kembali: jika palet terdiri dari merah dan biru, setengah rangkaian akan berwarna merah dan setengah lainnya biru.

Opsi
        var options = {
          legend: 'none',
          colors: ['black', 'blue', 'red', 'green', 'yellow', 'gray']
        };

Mengubah Ketebalan

Anda dapat mengontrol ketebalan garis dengan opsi lineWidth:

        var options = {
          legend: 'none',
          hAxis: { maxValue: 7 },
          vAxis: { maxValue: 13 },
          lineWidth: 10,
          colors: ['#e2431e', '#d3362d', '#e7711b',
                   '#e49307', '#e49307', '#b9c246']

      google.charts.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = google.visualization.arrayToDataTable

              [6, 7, 8, 9, 10, 11, 12]
        ]);

        var options = {
          legend: 'none',
          hAxis: { maxValue: 7 },
          vAxis: { maxValue: 13 },
          lineWidth: 10,
          colors: ['#e2431e', '#d3362d', '#e7711b',
                   '#e49307', '#e49307', '#b9c246']

    </script>
  </head>
  <body>
    <div id="chart_div" style="width: 900px; height: 500px;"></div>
  </body>

Untuk mengontrol lebar garis rangkaian, gunakan opsi series:

Opsi
        var options = {
          legend: 'none',
          hAxis: { maxValue: 7 },
          vAxis: { maxValue: 13 },
          series: {
            0: { lineWidth: 1 },
            1: { lineWidth: 2 },
            2: { lineWidth: 4 },
            3: { lineWidth: 8 },
            4: { lineWidth: 16 },
            5: { lineWidth: 24 }
          },
          colors: ['#e2431e', '#d3362d', '#e7711b',
                   '#e49307', '#e49307', '#b9c246']

Garis Putus-Putus

Banyak gaya garis putus-putus yang dapat dilakukan melalui opsi lineDashStyle, yang menggunakan array angka. Angka pertama menunjukkan panjang tanda pisah, dan angka kedua menunjukkan celah setelahnya. Jika ada angka ketiga, itu adalah panjang garis putus-putus berikutnya, dan angka keempat, jika ada, adalah panjang celah berikutnya.

Saat diagram digambar, panjang ini diulang, sehingga [4, 4] berarti urutan garis putus-putus 4 panjang dan celah 4 panjang. [5, 1, 3] berarti tanda pisah 5 panjang, celah 1 panjang, garis putus 3 panjang, celah 5 panjang, dan seterusnya. Beberapa contoh:

        var options = {
          hAxis: { maxValue: 10 },
          vAxis: { maxValue: 18 },
          chartArea: { width: 380 },
          lineWidth: 4,
