更快的数据绘图 

Mathematica 10 包括了对数据集绘图时的速度和内存使用的改进. 以下显示的是一些普通情况下使用的全计时和内存大小. 测试在 Intel Core i7 2.6 GHz Mac OS X 系统上实施.

对大型数据集的绘制速度提升了 40%.

用独特的标记绘制多个数据集更加快捷.

In[1]:=

X m10s3 = {{8, 8608}, {16, 9184}, {32, 10336}, {64, 12672}, {128, 17280}, {256, 26496}, {512, 44928}, {1024, 81792}};

In[2]:=

X m9s3 = {{8, 13208}, {16, 22296}, {32, 40472}, {64, 76824}, {128, 149816}, {256, 295736}, {512, 579544}, {1024, 1155032}};

用独特的标记绘制多个数据集会使用更小的内存.

In[3]:=

X ListLogLogPlot[{m9s3, m10s3}, PlotRange -> All, PlotTheme -> {"Grid", "OpenMarkers"}, ImageSize -> Large, PlotLabel -> Style["Graphics size for multiple datasets with individual markers", 14, Bold], PlotLegends -> Placed[{"Mathematica 9", "Mathematica 10"}, Below], AxesLabel -> {"length", "bytes"}, Joined -> True]
