Question

ODS图形选项可生成更好的图形，但似乎比基本图形长800倍。我通过各种不同的程序体验过这一点。 Windows 7上的平台是SAS 9.4。

Q1：这是典型/预期的吗？去年，我可以在同事的机器上以更快的速度制作ODS图表。

Q2：我如何加快速度，现在我可以比ODS图形更快地手动创建图表。基本的图表也不够专业，也许如果有一种方法可以使用抗锯齿字体自动将它们导出为体面的png或svg格式？（请记住，我想编写一个自动创建数千个图表的程序。）

问题3：我应该放弃ODS图形并切换回传统图形吗？

以下示例。如果你执行这段代码并查看日志中的执行时间，那么在ODS图形关闭的情况下，我会看到0.09秒的休假过程，在ODS图形打开的情况下，我会看到1：13.11秒甚至1：20.23秒。如果我另外请求html输出，则每个图表可能需要超过2分钟。

更新：我认为这与打印机（物理）访问有关。

Answer 1

原来这与打印机访问有关。

我注意到在其他桌面应用程序中，有时需要大约20秒才能访问远程默认打印机。

其次，我还注意到当我在可以访问打印机的网络上时，生成每个图表所花费的时间要少得多。

然后我将我的默认打印机切换为人造adobe pdf生成器。这将图表生成时间从1-2分钟缩短到0.09秒。

通过切换回无法访问的网络打印机可以重现效果，并通过切换离开网络打印机再次解决。

因此，每当生成图表时，PROC SHEWHART和其他操作都会延迟并等待联系网络打印机，即使它没有进入打印机。

ODS图形非常慢（800x慢）
