I’m new in Zenon and I’m using the Report Viewer (Repor-Visual Studio) tool in Zenon Supervisor.
I have a dataset with some variables and I’m trying to make a chart.
I’m writing in the expression the code to visualize the value, but it only shows the first variable in the dataset and it seems that I can’t choose within my variables.
I found functions “First” and “Last” that helped me choosing 2 of my variables in that dataset, I’m trying to figure out how to choose a variable that I desire from my dataset and not only the first or the last.
I also found the function “Choose” and it works for the first, writing Choose(1,Fields!VALUE.Value) it shows me the value of the first variable but it doesn’t work with 2 or 3 for the second and the third.
How can the system detect the first or the last of the variables? Are there any indexes to enter the “array” of variables? And what is the code to enter a cell of that array? Fields!VALUE.value(0) or something similar doesn’t work.
I’m looking for the way to select and show in the chart one of the n variables from a dataset, now I have n dataset for n variables because of this problem and it isn’t a good configuration.
Thank’s for your help.
