杂记 20120205 | Misc Notes 20120205

1. Javascript 图表库比较
Ext JS 各种模型比较折腾,画出来还不错。
flot,配合jQuery写着比较顺手,但是功能不够多,内置符号只有圆圈,加个插件发现图例中不能显示符号。logscale还有坐标的分点都要自己实现。。。

2.gnuplot编译时报错,libpng冲突

3.Excel中方向键不工作
按一下ScrollLock试试

1. A few JS libraries for plotting
Ext JS, with rather complicated data models, but worthy. Produced figures look good.
flot, a smooth coding experience with jQuery, but also lack of features. E.g. by default the only available symbol is circle. There are plugins available for extra symbols, but only in legend...Also I have to specify all the ticks...

2. libpng confliction when compiling gnuplot.

3. Arrow keys not working in excel
Try to press the ScrollLock key

4. To play white noise in Linux
install sox
play -n synth 60:00 whitenoise
