Variable Colour Scale

[JohnLloyd]

Can someone explain to me how to turn on the "variable colour scale" feature in VistaPro?

The button seems to be permanently greyed out.

I'm running VE 2012 Hotfix 2.

Hi,

To activate the button and access the feature you have to have selected a variable from the "Selected variable" list at the bottom (this way you are telling it what variable result to colour based on).

You also need to select a room(s) as it will only colour in the rooms you are interested in.

Thanks Phil, I'll have another look at it.

Is there a trick to select the right kind of data to display with the variable color scale?

I'm trying to play around with displaying a colored floor plan that represents different variables for each of the rooms - air temp, number of people, comfort conditions, etc.

It makes sense that you would NOT be able to select an array of data - like for each hour of a day - because the color scale feature would only be able to plot one color for each room at a given time. I'm not able to wake the button up so I can turn it on..

You can't display multiple variables on it at the same time, you can only colour a selection of rooms based on their results at any timestep for a single selected variable. It should work for air temp and if the rooms are conditioned differently then you should be able to see the variation of hot and cold rooms.

The next release will have input variable colouring available so you can colour rooms based on assigned thermal data e.g. set points or infiltration rates etc. That should be quiet useful for graphically displaying model data and by sounds of it might be closer to what you are aiming for here

How do you change the timestep that is displayed?

I have results from a dynamic simulation and i want to show the air temperature in a selection of rooms at say 14:45 on July the 19th.

I have selected the rooms i am interested in, the variable (air temperature) and the date but the timestep is stuck (greyed out) at 0:15.

Thanks in advance

You should be able to use the timestep slider to change it.
See the image below.

Got it now

I was making two errors.

1. trying to jump into the straight into the 'Visual Analysis (Model Viewer II)' rather than the variable colour scale

2. I didn't realize you had to select the variable of interest from the selected variable list to make the variable colour scale available.

Why is the variable colour scale and peak day graph showing different results for the same room?

on the 5th of July at 15:15 the variable scale is colour coding the air temperature to be around 20dC

Whilst the graph for the same day and time is up at 32+dC

The aps file you're interrogating, how big is it?
We've had some reports of people experiencing issues when results files are bigger than ~3Gb.

Have you tried using 'Visual Analysis (Model Viewer II)' to colour up the model?
It could be an issue with the old viewer.
