CIE色度图绘制。 从CIE1931数据点开始，光刺激波长从360nm到830nm，间隔1nm，很准确的马蹄形图。色度图中贴入CIE1976均匀色空间彩色映射图。同时画出BT709和BT2020三角形色域，D65坐标。需要表示色域覆盖的文章，是绝好的插图。-CIE chromaticity diagram plotted. Starting CIE1931 data point, light stimulation wavelengths　360nm to 830nm, interval 1nm, very accurate horseshoe FIG. Chromaticity diagram pasted into CIE1976 uniform color space color maps. BT709 and BT2020 simultaneously draw a triangle gamut, D65 coordinates. Need to represent the color gamut coverage of the article, it is the perfect illustration.
