php rrd_graphs评论位置几乎每次更改

Question

I have a problem with rrd graps - they look different every time. 我对rrd grap有问题-每次看起来都不同。

For example: these are 2 graphs generated one by one using the same function. 例如：这些是使用相同功能一张一张地生成的2张图。

My rrd_graph options looks like this: 我的rrd_graph选项如下所示：

"--slope-mode",
        "--start", $start,

        "--font=DEFAULT:9:Cantarell",
        "--font=TITLE:12:Roboto Condensed",
        "--font=AXIS:8:Roboto Condensed",
        "--font=LEGEND:9:Cantarell",
        "--font=WATERMARK:6:Cantarell",

        "--title=$title",
        "-W General",
        "--vertical-label=Tx[dBm] / Rx[dBm] / SNR[dB]",
        "--lower=0",
        "-w 550",
        "-h 300",
        "-P",
        "--border=0",
        "--color=BACK#ffffff",

I forgot to share the solution... I fixed a problem using 2 things: 我忘了分享解决方案...我用2件东西解决了一个问题：

Monospaced font. 等宽字体。

sprintf with fixed width strings: 带有固定宽度字符串的sprintf：

  sprintf('COMMENT:%25s%13s%13s%14s%13s', "", "Current", " Average", "Maximum", "Minimum"), "COMMENT:\\\\n", "COMMENT: \\\\n", "COMMENT:\\\\t", sprintf("LINE3:Rx#055499:%-9s%-10s", "DS Rx", "[dBm]"), sprintf("GPRINT:Rx:LAST:%-13s", "%4.1lf"), sprintf("GPRINT:Rx:AVERAGE:%-13s", "%4.1lf"), sprintf("GPRINT:Rx:MAX:%-13s", "%4.1lf"), sprintf("GPRINT:Rx:MIN:%-13s", "%4.1lf"), "COMMENT:\\\\n", "COMMENT:\\\\t", sprintf("LINE3:SNR#ff5a00:%-9s%-10s", "DS SNR", "[dB]"), sprintf("GPRINT:SNR:LAST:%-13s", "%4.1lf"), sprintf("GPRINT:SNR:AVERAGE:%-13s", "%4.1lf"), sprintf("GPRINT:SNR:MAX:%-13s", "%4.1lf"), sprintf("GPRINT:SNR:MIN:%-13s", "%4.1lf"), "COMMENT:\\\\n", "COMMENT:\\\\t", sprintf("LINE3:MR#4be117:%-9s%-10s", "MicroRef", "[-dBc]"), sprintf("GPRINT:MR:LAST:%-13s", "%4.1lf"), sprintf("GPRINT:MR:AVERAGE:%-13s", "%4.1lf"), sprintf("GPRINT:MR:MAX:%-13s", "%4.1lf"), sprintf("GPRINT:MR:MIN:%-13s", "%4.1lf"), "COMMENT:\\\\n",
