散景变化质量出口图

Question

I am trying to export some grid into either png or svg but with svg option—as the doc states-the plots are exported as multiple files. So the only option is png . (For some reason if I use the toolbar, I only get the first plot and not the other).

But the quality of the png is terrible. Is there an option to set dpi or whatever? Even I you try to save graphs on the official documentation, you obtain poor quality.

I really like Bokeh and found it nicer to use that any other libs but this quality export is critical for me (publication purpose).

在最新版本的Bokeh中， export_png接受width和height参数，您可以根据需要将其设置为任意大，例如：

export_png(p, "plot.png", width=2400, height=1000)
