@rucb, sorry if you have 10K-25K values which is 0 when not present, then it would mean each data point will show 25K splits. This seems to be too high, unless I have misunderstood. A mock screenshot of what you currently have will help (mask out any sensitive information).
Also, the reason why I asked above questions was that only if it is less number of splits and all the series are always present you can use approach as mentioned in above answer. Else you would need to request for an enhancement.
