 +We are nearly finished! Let's open up Grafana. Start with creating a new dashboard by hovering over "plus"-icon on the left side of the screen and select ''%%Dashboard%%''. Add a new panel. In the query-part select under ''%%FROM -> select measurement%%'' the value name you gave the measurement in Node-Red. Under ''%%SELECT%%'' remove ''%%mean()%%'' and put in ''%%distinct%%'', so you get a nice line graph. We can now do some more advanced stuff. We know that the lab temperature will always be in a range from 0 to 40 degrees. When we open up the tab ''%%Axes%%'' on the right side, we can set for ''%%Left Y%%'' (so the left Y-axis) the ''%%Y-Min%%'' to 0 and the ''%%Y-Max%%'' to 40. You can also change the name of the graph under ''%%Settings%%''-tab. Click ''%%Save%%'' and ''%%Apply%%'' if you are finished and that's it. Look at your nice little graph!
