  Hi, I have 3 CSV’s which I would like to render in same chart. I used the logic provided for dynamic length of datapoints in the forum and enhanced it for 3 CSV. But I see that chart is plotting x-axis 3 times.
  CSV is like :
  CSV1
  Time[usec],s1_server32,s1_server34,s1_server40,s1_server41,s1_server42,s1_server43,s1_server44,s1_server45,s1_server47,s1_server48
  15,8.48,8.53,8.68,8.5,8.6,8.65,8.75,8.48,8.61,8.55
  30,8.43,8.44,8.45,8.44,8.44,8.45,8.41,8.46,8.47,8.46
  45,8.44,8.44,8.45,8.44,8.44,8.45,8.41,8.45,8.47,8.45
  60,8.43,8.43,8.45,8.44,8.43,8.45,8.41,8.46,8.47,8.45

  CSV2
  Time[usec],s2_server32,s2_server34,s2_server40,s2_server41,s2_server42,s2_server43,s2_server44,s2_server45,s2_server47,s2_server48
  15,8.48,8.53,8.68,8.5,8.6,8.65,8.75,8.48,8.61,8.55
  30,8.43,8.44,8.45,8.44,8.44,8.45,8.41,8.46,8.47,8.46
  45,8.44,8.44,8.45,8.44,8.44,8.45,8.41,8.45,8.47,8.45
  60,8.43,8.43,8.45,8.44,8.43,8.45,8.41,8.46,8.47,8.45

  CSV3
  Time[usec],server32,server34,server40,server41,server42,server43,server44,server45,server47,server48
  15,17.13,17.18,17.46,17.13,17.31,17.36,17.73,17.15,17.21,17.19
  30,17.08,17.09,17.08,17.09,17.08,17.08,17.08,17.09,17.08,17.08
  45,17.09,17.09,17.08,17.08,17.09,17.08,17.08,17.08,17.08,17.08
  60,17.08,17.08,17.09,17.09,17.09,17.09,17.09,17.09,17.08,17.08

  Hi Manoj, the result works partially. When there is lesser columns in the CSV I don’t see the lines getting plotted. I see that sometimes it will plot and sometimes its blank. Screenshot for the case :

  60,20.98,21.58

  How to debug this?

  @manuks,

  It seems like you are setting axisY maximum to 20. Removing maximum should work fine in your case.
