For a specific project I had a grid something like this :
>Depth
>totalSO4
>dissolvedO
>NH3
>NH4
>pH
>Temperature
>Salinity
>...
>
>Users were entering/updating data and their data was being validated against possible ranges. Well ranges cannot quite prevent erronous data. Say they could enter these w/o breaking range (Salinity might be in range 44-75 : just imaginery, scientist do know them not me :)
>

(meters)
>Depth Salinity
>----- --------
>0      44
>1      44.1
>2      44
>3      70 ---> Ooops. It shouldn't change this far.
>4      46

I couldn't find a good and fast way to check these online. So my workaround was to show a line graph against depth per parameter below the grid. While the data is in allowable range users could see it makes a "peak" as soon as they enter a value like above. Or a viewer-checker could better say data is erronous at a glance w/o checking the data one by one (even I caught their erronous data w/o an idea about the ranges:)
>What I did was to create a specific line graph container class. For each subclass dropped on form I only changed properties "Label" (tSO4, NH3...) and fieldname that graph is drawn for (and a few optional like line color, mark color..). Class was SQL selecting depth and values for the field, sizing them, and drawing lines for the values.

This is exactly the type of thing that I'm doing. In my case its Pressure against temperature - as pressure increases, the maximum allowable temperature should decreases. Each set of figures produces an arch which can be clearly seen with a graph.

I would be most grateful if you could dig out the class. It would save me so much time (and embarrassment if I get it wrong).
