Your issue is that chart values has create multi-value fields of different lengths. However, starting from the chart you have created, you could do something like this:
| makeresults
| eval _raw="sort,2941,2945,2946,2948,2950,2951,2952,2954,2955,2957,OTHER
50,2330,2180,2050,2180,2520,1740,2120,2830,2330,2050,1150
50,2890,2700,2700,3230,3290,2770,3360,2890,2520,2830,1210
50,,,,,,,,,,,1280
50,,,,,,,,,,,1340
50,,,,,,,,,,,1400
50,,,,,,,,,,,1490
60,2335,2185,2055,2185,2525,1745,2125,2835,2335,2055,1155
60,2895,2705,2705,3235,3295,2775,3365,2895,2525,2835,1215
60,,,,,,,,,,,1285
60,,,,,,,,,,,1345
60,,,,,,,,,,,1405
60,,,,,,,,,,,1495"
| multikv forceheader=1
| fields - _* linecount
| untable sort HoleNb Torque
| chart useother=f values(Torque) as Torque by sort HoleNb
``` The above creates a chart similar to yours. I added an extra sort value in case you actually have more than one row. ```
| streamstats count as row
| foreach *
[| eval mvc_<<FIELD>>=mvcount('<<FIELD>>')]
| foreach mvc_*
[| eval max_rows=if(isnull(max_rows),'<<FIELD>>',if('<<FIELD>>'>max_rows,'<<FIELD>>',max_rows))]
| fields - mvc_*
| streamstats sum(max_rows) as top_row
| append
[| makeresults
| eval top_row=1
| eval row=1
| fields - _time]
| makecontinuous top_row
| sort - top_row
| filldown
| sort row top_row
| streamstats count as mvrow by row
| fields - max_rows row top_row
| foreach *
[| eval <<FIELD>>=if("<<FIELD>>"!="sort" AND "<<FIELD>>"!="mvrow",mvindex('<<FIELD>>',mvrow-1),'<<FIELD>>')]
| fields - mvrow
