How to remove gridlines and grid labels in Chartjs Radar?


With chartjs 2 type RADAR, how can you remove the gridlines and gridline labeling to make a radar chart more similar to the desired radar chart seen below?

Current:

chartjs radar

Desired:

chart js


Solution

  • To remove/diminish grid-lines, you can set maxTicksLimit property of ticks to a number (amount of grid-lines - approx.) , like so :

    scale: {
       ticks: {
          maxTicksLimit: 3
       }
    }
    

    BONUS: If you wish to remove all the grid-lines, setting maxTicksLimit to 0 will not work. Instead add the following in your chart options :

    gridLines: {
       display: false
    }
    

    To remove grid-line labels (ticks), you can set display property to false for scale ticks , as such :

    scale: {
       ticks: {
          display: false
       }
    }
