I have three questions need your help. I am developing now venapp for groundwater decision support system.
The first question : assume you are giving the user the possibility to change a number of parameters (A, B, C) in the model, But you need the user get error message (with model can’t simulate) if the total values of these three parameters exceed let say 100.
Can I make the WIP figures displayed into bar graph
Can I change x axis instead of time 1-100 to name of month plus year (Jan 93).
Your assistance with this matter is much appreciated

There are a couple of approaches to the first - one is to use SLIDEVARTIE so that they never add up to more than 100. Another is to use TEST - the example in the manual does exactly what you want. Note that the three numbers to be added need to be constants, not equations.
The custom bar graph has a :WIP keyword - see Chapter 15 of the Reference Manual. WIP bar graph can be confusing because they change so quickly.
You can define a time base as decimal year, this is simplest.
You can also use custom xaxis labels using the X-DIV keyword. - again Chapter 15 of the reference manual.
