Tweaking

Search for the file we know to contain style we want to change:

find . -name "rpimonitor.css" 2>/dev/null

1. changed width: 518px; into width: 300px;:
2. changed nowrap into normal:

sudo nano -l +63 /usr/share/rpimonitor/web/css/rpimonitor.css

.Text {
  float: left;
  font-family: Tahoma, Helvetica;
  font-size: 13px;
  line-height: 13px;
  padding-left: 30px;
  padding-right: 30px;
  padding-top: 15px;
  width: 300px; // 518px
  white-space: normal ; // nowrap;
}

Reduce graph width

Changed graph_width:"750px" into graph_width:"400px":

sudo nano -l +174 /usr/share/rpimonitor/web/js/rpimonitor.statistics.js

...
rrdflot_defaults={ graph_width:"400px",graph_height:"285px", scale_width:"350px", scale_height:"90px", use_rra:true, rra:active_rra };
