我正在使用Gnuplot 4.7中的SVG终端并尝试在浏览器上同时使用超文本和超链接，通过鼠标悬停和鼠标点击分别在绘制的数据点上激活。鼠标悬停工作得益于我之前提问的stackoverflow的帮助。
我的数据输入文件如下所示：
X Y标签颜色超链接
0 0 net0 2 net0.txt
1 1 net1 2 net1.txt
2 2 net2 2 net2.txt
3 4 net3_outlier 1 outlier.txt
4 4 net4 2 net4.txt
我的脚本script.gp如下所示：
set terminal svg/canvas enhanced mousing
set palette model RGB defined (0 'blue', 1 'red', 2 'green')
plot 'test.txt' using 1:2:3:4 with labels hypertext point pt 7 ps var lc variable
结果： 我可以根据文件中的第4列以及文件中第3列的悬停超文本标签，使用红色和绿色点绘制颜色。我的试验是让数据中的column5成为从图中点开始的文件的超链接。所以将鼠标悬停在该点上，显示超文本并单击它应打开超链接。这可能吗？如果有必要，我可以对后处理生成的html文件进行后处理，只是不知道要添加什么以及在哪里。
测试： 我正在使用gnuplot 4.7和firefox 5.0
输出html文件如下所示： 我在这里看到一些hrefs，但无法确定我是否可以在这里添加文件的超链接。此外，我更喜欢Canvas，因为XY桌子显示出鼠标坐标。

帮助表示感谢。我是Gnuplot的新手，但试图加快速度。
