tic和标签gnuplot 5.4中的字母重叠 [英] Overlapping letters in tics and labels gnuplot 5.4

问题描述

我最近将gnuplot更新为最新的5.4.我使用pngcairo终端发现了标签和抽签的问题.例如，以官方网站上的简化示例为例

I have recently updated my gnuplot to the latest 5.4. I find problems with the labels and tics using the pngcairo terminal. For example, taking a simplified example from the official website

set terminal pngcairo enhanced font "arial,20" fontscale 1.0 size 600, 400 
set output 'pm3d6.png'
set pm3d map
splot sin(sqrt(x**2+y**2))/sqrt(x**2+y**2)

我得到一个看起来不错的图形，但是标签和抽签中的字母以一种奇怪的方式重叠.知道为什么会这样吗?

I get a figure that looks fine, but letters in the labels and tics overlap in a strange way. Any idea about why this happens?

推荐答案

pango/cairo库中很可能是一个已知错误.我看到的唯一解决方案是降级到libpango的工作版本(1.43而不是1.44). 见

Very likely a known bug in the pango/cairo libraries. The only solution I have seen is to downgrade to a working version of libpango (1.43 rather than 1.44). See
