how to remove fraction part of numbers on time scale

Post by kma »

When I plot sensitivity curves of 20 plots, I get fraction parts on time scales, such as 20.99, 40.98, etc. How to make the time-axis print just 20 and 40?

Also, I am running the simulation for 50 years, with time step of a day. I am currently setting time step = 1/365. Is there a way to specify day as the time step, while saving values every year?

Thank you in advance.

Perhaps you are starting at time 1 instead of time 0. That might explain the odd numbers. If you have 49 years you would need to set x divisions to 7 to get round numbers on the division points. Anything else will necessitate the funny cutoffs.

You can use the TIME BASE function or the date display functionality to show values on the time axis different from the time scale in the model. If you switch to day all measurement (delay times etc) need to be in day and not year.

how to remove fraction

Hi

I am wondering what could justify a model with a day time step and a horizon of 50 years!
The time step is too short or the horizon is too long.
That seems totally unadapted unless in some very special occasions that I would like to know.
Regards.

HI JJ,

I am running a HIV transmission model for a population. I am analyzing the outcomes for 50 years while transmission is executed on a daily basis.

Hi

Is it a closed model, without or with little exogenous influence or an open model with exogenous data not modelled?
