<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>”。</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 'set term svg;set output; plot x'</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>
