Control chart sorting on X axis

[#1]

Hi I am struggling to sort data on the x axis within  control chart builder and via the IMR Control Chart .  In the example attached I drag the X variable of 95 values, I deliberately reverse 90 and 91 in the data set, but on a control chart it keeps it 91 then 90. 

In graph builder it allocates the correct run order of 90, 91.

I have tried value ordering and this does not seem to work - I played around with different data formats but nothing seemed to work for me

I know I can sort data and then it works but I dont want to keep sorting columns - my data table is massive, I rather rely upon a column with correct order to assess the data

With JMP19 you might have to enable Sort by subgroup

Hi Jarmo, thank you so much for this it works perfectly. I saw the Subgroup option before but missed the enabling function you showed me above, this is so important in running a control chart to ensure the data is always in the correct order

Wonderful - cheers
