## Select column to show in a graph/card

Good afternoon.

I'm quite new to PBI, then I need some help to do one thing:

I have a system that measures temperature and humidity and records it into a .txt file, separating columns by "tab".

But I want to make possible that the user can select the temperature unit.

I have, originally, on the .txt, a column with temperatures in Celsius, and made two other ones, where the PBI will calculate the respective values in Kelvin and Fahrenheit units.

I want to show it into a graph, and also show the maximum, minimum and average values in a day, but for it I want to use a combo box, where the user will select the temperature unit.

And there is my problem: How can I select a column to show into something, depending on the selection of the user?

I'll send some prints for you to understand it better:

In this last print, I only want to show one of these columns, selected by the user. How can I do it?

To do this, you can use the approach described in this article.

https://www.fourmoo.com/2017/11/21/power-bi-using-a-slicer-to-show-different-measures/

Also, you don't need to make calculated columns for Kelvin and Farenheit.  You can just have a measure for each.  For example,

Farenheit Temp = [Celsius Temp] * 9/5 + 32

Where [Celsius Temp] is the measure on your Celsius temp column (e.g., AVERAGE(Table[TemperaturaCelsius]).  If each data point on the chart is a single value, the aggregation won't matter (max, min, sum, average).

You can then have a SWITCH measure that returns the result of one of the measures (Celsius, Kelvin, Farenheit).

Thank you for the incredibly quick answer. I've thought about using measures, but I really don't know how.

When I've tried it, the measure was only using average/sum values, and I don't want it. I want all the values to be plotted. I not even know how to properly create a measure.

The switch function I also don't know how to use.

Can you help me with it?
