<li>确保gnuplot正确安装在Termux提示符下敲入gnuplot,然后回车保证出现”gnuplot&gt;”。</li>
2019-04-18 16:13:11 +00:00
<li>确保gnuplot正常运行, 在Termux提示符下执行下面命令<br><code>gnuplot -e &#39;set term svg;set output; plot x&#39;</code><br>屏幕输出应该为正常的svg文件类似html文本</li>
2019-03-04 07:04:48 +00:00
<li>Termux应为uweb定制包否则有一堆设定需要修改。</li>
<li>超微浏览器下长按窗口管理按钮,勾选“标准错误输出”。再次在地址栏执行画图操作,此时浏览器会显示出错信息。</li>
2019-03-04 07:15:13 +00:00
<li>为保证地址栏输入函数符合gnuplot规范首个测试函数建议为”x”即整个地址栏内输入为”x”。</li>
