The sum column = quantity which arrives, each day for each container (we have many , of which I present by place, by type of material inside and so on) . This table chart show the sum by container , and aggregated by let Factory >> Factory Group >> Geographic Area. But this I have managed to do in the chart.
Surly the first day, from which we started to collect data will have no yesterday info value.
The 7 was just an example from the previous day, but maybe I was not clear enough.
The idea in total is , once I have the correct expression from the day before I can show in the yesterday column the GAP (today-yesterday) - that is my final goal.
Your help will be appreciated.
There are a few different approaches to take here.
The easiest solution is using the above() function, which will always return the value from the chart line above the current line. Keep in mind that the first line in your chart will always show NULL as the above() value. This solution can only work in a chart by Date, of course.
A more generic solution involves building a special table in your dataset. We usually call it the "As of Date" table. In this table, we associate the "display" date with the "transaction" date and assign a number of conditional flags, for example "Current Date" flag and the "Previous Date" flag. Your can find plenty of documents describing how to use the "As of Date" table, including my blog.
I also described it in great detail in my book "QlikView Your Business".
Sorry for the late response BUT i have managed to bring en example:
Attached is a photo in which maybe my problem will be clear:
In this photo you can see that all the point are spread near one SINGLE Y-Axis greed line.
I would have expect the greed line to automatically changed, In this zoom-in example, to a range between 89-91 and with jump of 1/3 or 1/2 or something similar so the user can see the little differences between the values.
AGAIN, I would have not expect the range to be smaller if one of the points was out of range.
I would appreciate your input in this issue.
